Im New In Development think and i'm wondering about some things like the game center button , how to connect that button is there any ready code for that, the same question about the rate button . Can any one tell me how to do that
//Rate Button
if ([node.name isEqualToString:#"rateButton"]) //Your Rate Button name
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"itms-apps://itunes.apple.com/app/id919770861"]];//itms-apps://itunes.apple.com/app/idYourAppID
}
//Game Center Button
- (void)showGKGameCenterViewController:
(UIViewController *)viewController
{
if (!_enableGameCenter) {
NSLog(#"Local play is not authenticated");
}
GKGameCenterViewController *gameCenterViewController =
[[GKGameCenterViewController alloc] init];
gameCenterViewController.gameCenterDelegate = self;
gameCenterViewController.viewState =
GKGameCenterViewControllerStateAchievements;
[viewController presentViewController:gameCenterViewController
animated:YES
completion:nil];
}
if ([node.name isEqualToString:#"GameCenter"]) //Your Game Center Button Name
{
[self showGKGameCenterViewController:yourViewController];

I want to add another menu option to the default image attachment menu options (Copy Image, Save to Camera Roll). Note that these options are shown when you long press on an image embedded in the UITextView if the textView is not in editing mode.
I have tried adding a custom menu to the uimenucontroller and using -(void)canPerformAction to enable or disable the option, however this seems to add the menu item to the uitextView's edit menu and has no affect on the attachments popup menu.
-(void)canPerformAction never seems to get called when long pressing on the image attachment.
Well according to Apple there is no public API for doing this, however as it turns out its relatively straight forward to replace the default menu with one that looks and behaves the same.
In the viewController that contains the UITextView add the following or similar and set it up as the textView's delegate.
- (BOOL)textView:(UITextView *)textView shouldInteractWithTextAttachment:(NSTextAttachment *)textAttachment inRange:(NSRange)characterRange {
// save in ivar so we can access once action sheet option is selected
_attachment = textAttachment;
[self attachmentActionSheet:(UITextView *)textView range:characterRange];
return NO;
}
- (void)attachmentActionSheet:(UITextView *)textView range:(NSRange)range {
// get the rect for the selected attachment (if its a big image with top not visible the action sheet
// will be positioned above the top limit of the UITextView
// Need to add code to adjust for this.
CGRect attachmentRect = [self frameOfTextRange:range inTextView:textView];
_attachmentMenuSheet = [[UIActionSheet alloc] initWithTitle:nil
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"Copy Image", #"Save to Camera Roll", #"Open in Viewer", nil];
// Show the sheet
[_attachmentMenuSheet showFromRect:attachmentRect inView:textView animated:YES];
}
- (CGRect)frameOfTextRange:(NSRange)range inTextView:(UITextView *)textView {
CGRect rect = [textView.layoutManager boundingRectForGlyphRange:range inTextContainer:textView.textContainer];
// Now convert to textView coordinates
CGRect rectRange = [textView convertRect:rect fromView:textView.textInputView];
// Now convert to contentView coordinates
CGRect rectRangeSuper = [self.contentView convertRect:rectRange fromView:textView];
// Get the textView frame
CGRect rectView = textView.frame;
// Find the intersection of the two (in the same coordinate space)
CGRect rectIntersect = CGRectIntersection(rectRangeSuper, rectView);
// If no intersection then that's weird !!
if (CGRectIsNull(rectIntersect)) {
return rectRange;
}
// Now convert the intersection rect back to textView coordinates
CGRect rectRangeInt = [textView convertRect:rectIntersect fromView:self.contentView];
return rectRangeInt;
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (actionSheet == _attachmentMenuSheet) {
switch (buttonIndex) {
case 0:
[self copyImageToPasteBoard:[_attachment image]];
break;
case 1:
[self saveToCameraRoll:[_attachment image]];
break;
case 2:
[self browseImage:[_attachment image]];
break;
default:
break;
}
}
}
- (void)saveToCameraRoll:(UIImage*)image {
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
}
- (void)copyImageToPasteBoard:(UIImage*)image {
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
NSData *data = UIImagePNGRepresentation(image);
[pasteboard setData:data forPasteboardType:#"public.png"];
}
-(void)browseImage:(UIImage*)image

UIImage *img = [[UIImage alloc] initWithData:UIImagePNGRepresentation(image)];

In my iOS app I have a Map View that I called mappa.
I just add a UIActivityViewController that appears when a callout is pressed from an annotation View.
I use this code to display it:
- (void)mapView:(MKMapView *)mapView
annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control {
[mappa deselectAnnotation:view.annotation animated:YES];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 6.0) {
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[self, [NSURL URLWithString:#"http://www.AppStore.com/iToretto"]]
applicationActivities:nil];
activityViewController.excludedActivityTypes = #[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard ];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:activityViewController];
self.annotationPopoverController = pop;
//show the popover next to the annotation view (pin)
[pop presentPopoverFromRect:view.bounds
inView:view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
self.annotationPopoverController.delegate = self;
}
}
}
My problem is that when I rotate this popover, I have a frame Issue (like this). I understand that the solution is to override :
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration;
But when I try to display popover in landscape mode in this way I have multiple errors:
if (UIInterfaceOrientationLandscapeLeft && [self.annotationPopoverController isPopoverVisible]) {
[self.annotationPopoverController presentPopoverFromRect:view.bounds
inView:view
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
Because "view.bounds" and "view" is a local declaration of MKAnnotation
So, How can I fix it?! Does anyone have a solution?! Thanks in advance.
I have a music button in the main UI of iOS and I want the button function as stop music button and at the same time can play the music again. My problem is I can only stop the music but can't play it again. Here is my iOS code in xcode4. How can I define one button for both play and stop music button? I have assigned one button for both stopMusic and playMusic but it doesn't work.
- (IBAction)stopMusic{
self.playBgMusic.enabled = YES;
[self.player stop];
}
- (IBAction)playMusic{
self.playBgMusic.enabled = YES;
[self.player play];
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"music" ofType:#"mp3"];
self.player=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
player.delegate = self;
[player play];
player.numberOfLoops = -1;
[super viewDidLoad];
}
Rather than have a single button try to send two different messages (stopMusic, playMusic), have it send toggleMusic every time. The toggleMusic method can then stop or play the music based on the current state of the player.
- (IBAction)toggleMusic{
if ([self.player isPlaying] == YES) {
[self.player stop];
} else {
[self.player play];
}
self.playBgMusic.enabled = YES;
}
i want to show leaderbord in my own game ....i am using following method for that but noting happen ... i am confuse with rootview controller as my game is developed in cocos2d so there is nothing like dat :(
// Leaderboards
-(void) showLeaderboard
{
if (isGameCenterAvailable == NO)
return;
GKLeaderboardViewController* leaderboardVC = [[[GKLeaderboardViewController alloc] init] autorelease];
if (leaderboardVC != nil)
{
leaderboardVC.leaderboardDelegate = self;
[self presentViewController:leaderboardVC];
}
}
///
-(void) leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController
{
[self dismissModalViewController];
[delegate onLeaderboardViewDismissed];
}
///////
-(UIViewController*) getRootViewController
{
return [UIApplication sharedApplication].keyWindow.rootViewController;
}
///
-(void) presentViewController:(UIViewController*)vc
{
UIViewController* rootVC = [self getRootViewController];
[rootVC presentModalViewController:vc animated:YES];
}
////
-(void) dismissModalViewController
{
UIViewController* rootVC = [self getRootViewController];
[rootVC dismissModalViewControllerAnimated:YES];
}
...

i dont know but it work for me.if anyone can describe the real reason for why this working in this way i will be very glad....i call it through appdelegate
[(myAppDelegate*)[[UIApplication sharedApplication] delegate]gameCenter];
and from appdelegate i call rootviewcontroller method like
-(void)gameCenter
{
[rootViewController gameCenterLeaderboard];
}
and in rootviewcontroller there is a method
-(void)gameCenterLeaderboard
{
GKLeaderboardViewController* leaderboardVC = [[[GKLeaderboardViewController alloc] init] autorelease];
if (leaderboardVC != nil) {
leaderboardVC.leaderboardDelegate = self;
[self presentModalViewController: leaderboardVC animated: YES];
}
}
the following method is also override in rootviewcontroller
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)leaderboardController
{
[self dismissModalViewControllerAnimated:YES];
}
If you don't have a root UIViewController then I'd recommend creating a new UIViewController set it's view to your openGLView then use that view controller to present the leaderboard as a modal view controller.
UIViewController *leaderboardViewController = [[UIViewController alloc] init];
[leaderboardViewController setView:[[CCDirector sharedDirector] openGLView]];
[leaderboardViewController presentModalViewController:leaderboardVC animated:YES]; //leaderboardVC is your GKLeaderboardViewController
I am trying to capture tap event on my MKMapView, this way I can drop a MKPinAnnotation on the point where user tapped. Basically I have a map overlayed with MKOverlayViews (an overlay showing a building) and I would like to give user more information about that Overlay when they tap on it by dropping a MKPinAnnotaion and showing more information in the callout.
Thank you.
You can use a UIGestureRecognizer to detect touches on the map view.
Instead of a single tap, however, I would suggest looking for a double tap (UITapGestureRecognizer) or a long press (UILongPressGestureRecognizer). A single tap might interfere with the user trying to single tap on the pin or callout itself.
In the place where you setup the map view (in viewDidLoad for example), attach the gesture recognizer to the map view:
UITapGestureRecognizer *tgr = [[UITapGestureRecognizer alloc]
initWithTarget:self action:#selector(handleGesture:)];
tgr.numberOfTapsRequired = 2;
tgr.numberOfTouchesRequired = 1;
[mapView addGestureRecognizer:tgr];
[tgr release];
or to use a long press:
UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc]
initWithTarget:self action:#selector(handleGesture:)];
lpgr.minimumPressDuration = 2.0; //user must press for 2 seconds
[mapView addGestureRecognizer:lpgr];
[lpgr release];
In the handleGesture: method:
- (void)handleGesture:(UIGestureRecognizer *)gestureRecognizer
{
if (gestureRecognizer.state != UIGestureRecognizerStateEnded)
return;
CGPoint touchPoint = [gestureRecognizer locationInView:mapView];
CLLocationCoordinate2D touchMapCoordinate =
[mapView convertPoint:touchPoint toCoordinateFromView:mapView];
MKPointAnnotation *pa = [[MKPointAnnotation alloc] init];
pa.coordinate = touchMapCoordinate;
pa.title = #"Hello";
[mapView addAnnotation:pa];
[pa release];
}
I setup a long press (UILongPressGestureRecognizer) in viewDidLoad: but it just detect the only one touch from the first.
Where can i setup a long press to detect all touch? (it means the map ready everytime waiting user touch to screen to push a pin)
The viewDidLoad: method!
- (void)viewDidLoad {
[super viewDidLoad];mapView.mapType = MKMapTypeStandard;
UILongPressGestureRecognizer *longPressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(handleLongPressGesture:)];
[self.mapView addGestureRecognizer:longPressGesture];
[longPressGesture release];
mapAnnotations = [[NSMutableArray alloc] init];
MyLocation *location = [[MyLocation alloc] init];
[mapAnnotations addObject:location];
[self gotoLocation];
[self.mapView addAnnotations:self.mapAnnotations];
}
and the handleLongPressGesture method:
-(void)handleLongPressGesture:(UIGestureRecognizer*)sender {
// This is important if you only want to receive one tap and hold event
if (sender.state == UIGestureRecognizerStateEnded)
{NSLog(#"Released!");
[self.mapView removeGestureRecognizer:sender];
}
else
{
// Here we get the CGPoint for the touch and convert it to latitude and longitude coordinates to display on the map
CGPoint point = [sender locationInView:self.mapView];
CLLocationCoordinate2D locCoord = [self.mapView convertPoint:point toCoordinateFromView:self.mapView];
// Then all you have to do is create the annotation and add it to the map
MyLocation *dropPin = [[MyLocation alloc] init];
dropPin.latitude = [NSNumber numberWithDouble:locCoord.latitude];
dropPin.longitude = [NSNumber numberWithDouble:locCoord.longitude];
// [self.mapView addAnnotation:dropPin];
[mapAnnotations addObject:dropPin];
[dropPin release];
NSLog(#"Hold!!");
NSLog(#"Count: %d", [mapAnnotations count]);
}
}
If you want to use a single click/tap in the map view, here's a snippet of code I'm using. (Cocoa and Swift)
let gr = NSClickGestureRecognizer(target: self, action: "createPoint:")
gr.numberOfClicksRequired = 1
gr.delaysPrimaryMouseButtonEvents = false // allows +/- button press
gr.delegate = self
map.addGestureRecognizer(gr)
in the gesture delegate method, a simple test to prefer the double-tap gesture …
func gestureRecognizer(gestureRecognizer: NSGestureRecognizer, shouldRequireFailureOfGestureRecognizer otherGestureRecognizer: NSGestureRecognizer) -> Bool {
let other = otherGestureRecognizer as? NSClickGestureRecognizer
if (other?.numberOfClicksRequired > 1) {
return true; // allows double click
}
return false
}
you could also filter the gesture in other delegate methods if you wanted the Map to be in various "states", one of which allowed the single tap/click
For some reason, the UIGestureRecognizer just didn't work for me in Swift. When I use the UIGestureRecognizer way. When I used the touchesEnded method, it returns a MKNewAnnotationContainerView. It seems that this MKNewAnnotationContainerView blocked my MKMapView. Fortunately enough, it's a subview of MKMapView. So I looped through MKNewAnnotationContainerView's superviews till self.view to get the MKMapView. And I managed to pin the mapView by tapping.
Swift 4.1
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let t = touches.first
print(t?.location(in: self.view) as Any)
print(t?.view?.superview?.superview.self as Any)
print(mapView.self as Any)
var tempView = t?.view
while tempView != self.view {
if tempView != mapView {
tempView = tempView?.superview!
}else if tempView == mapView{
break
}
}
let convertedCoor = mapView.convert((t?.location(in: mapView))!, toCoordinateFrom: mapView)
let pin = MKPointAnnotation()
pin.coordinate = convertedCoor
mapView.addAnnotation(pin)
}
