Well i can't get this too work. My goal is too add a UIButton into Minecraft Pocket Edition. I think the problem is easy or obvious, so please don't get destracted by the small wall of code.
Thanks soo much,
Kivifreak
#import <substrate.h>
#import <UIKit/UIKit.h>
#interface Tpschanger
UIButton *myButton;
UIView *myView;
-(void) TPSButton;
#end
%hook minecraftpeViewController
-(void)viewDidLoad {
myView=[[UIView alloc]initWithFrame:CGRectMake(0,0,320,480)];
myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame = CGRectMake(20, 20, 200, 44);
[myButton setTitle:#"TPS" forState:UIControlStateNormal];
[myButton addTarget:self action:#selector(TPSButton:) forControlEvents:UIControlStateNormal];
[self.myView addSubview:myButton];
> I get an error at the previous line: request for member ‘myView’ in ‘self’, which is of non-class type ‘minecraftpeViewController*’
%orig;
}
%new
-(void) TPSButton {
}
%end
It should be [self.view addSubview:myButton]; IMO you don't need myView.

I am having issues not being able to close CDVViewController when calling this custom refresh, it stays loaded in the background and loads a new one causing memory leaks/high memory usage. I have tried to use both release and removeFromSuperview for the webView, subview, CDVViewController, ChildViewController but none of them work. I am running a Tab Bar Controller via Storyboard, (another reason why I have to call CDVViewController as a subview) and when I use the web inspector via safari I can see the pages building up on that tab, and when I refresh on another tab (not using CDVViewController/phonegap) it works fine. Any help is much appreciated.
So here is my .h
#import <UIKit/UIKit.h>
#import <ifaddrs.h>
#import <arpa/inet.h>
#import <Cordova/CDVViewController.h>
#interface ThirdViewController : CDVViewController <UIWebViewDelegate>
{
IBOutlet CDVViewController *webView;
IBOutlet UIActivityIndicatorView *activityind;
}
- (IBAction)Refresh:(id)sender;
#end
And my .m
#interface ThirdViewController ()
#end
#implementation ThirdViewController
- (void)viewDidLoad
{
webView = [CDVViewController new];
webView.startPage = #"MYWEBSITE";
[self addChildViewController:webView];
[self.webView addSubview:webView.view];
webView.view.frame = CGRectMake(0, 0, 0, 0);
[activityind startAnimating];
[self.webView addSubview: activityind];
[self CustomActivity];
}
-(void) CustomActivity
{
if ([webView.reference isEqualToString:#"TRUE"]){ //webView.reference is something I added into phonegap CDVViewController so that I am able to see when it is being loaded/used to load the custom activity/activity ind to work.
[activityind removeFromSuperview];
}else{
[NSTimer scheduledTimerWithTimeInterval:.5 target:self selector:#selector(CustomActivity) userInfo:nil repeats:NO];
}
}
- (IBAction)Refresh:(id)sender {
webView = [CDVViewController new];
webView.startPage = #"MYWEBSITE";
[self addChildViewController:webView];
[self.webView addSubview:webView.view];
webView.view.frame = CGRectMake (0,0,self.view.frame.size.width,(self.view.frame.size.height -44));
[activityind startAnimating];
[self.webView addSubview: activityind];
[self CustomActivity];
}
- (void)webViewDidStartLoad:(UIWebView *)webView {}
- (void)webViewDidFinishLoad:(UIWebView *)subview {}
- (void)loading {}
- (void)didReceiveMemoryWarning{[super didReceiveMemoryWarning];}
#end
Found the solution, I had to implement [webView.webView reload];
- (IBAction)Refresh:(id)sender {
[webView.webView reload];
}
I have a small UIView that I hide/show in to show a message to the user. The message itself is in a UITextView that I add to the small UIView that gets shown.
The sliding-in and sliding-out works fine - but the prior messages are not cleared. I have spent enough time to fix the problem - but to no avail. Can someone lend me their eyes!!
Here is how the UITextField is created programatically:
#interface MessageVC : UIViewController {
UITextView *messageTV;
}
#property (nonatomic, retain) UITextView *messageTV;
- (id)init;
- (void)showMsg:(NSString *)title;
#end
and
- (id)init {
if (self = [super init]) {
self.view = [[[UIView alloc] initWithFrame:CGRectMake(0, 380, 320, 100)] autorelease];
[self.view setBackgroundColor:[UIColor blackColor]];
}
return self;
}
- (void)showMsg:(NSString *)title {
[self setMessageTV : [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 315, 90 )]];
[[self messageTV] setBackgroundColor : [UIColor greenColor]];
[[self messageTV] setTextColor : [UIColor whiteColor]];
[[self messageTV] setText:#""]; <<<<<<<< - does not clear the text
[[self messageTV] setText : title];
[self.view addSubview : [self messageTV]];
[self.view setHidden:NO];
}
- (void) hideMessage {
[self.view setHidden:YES]
}
I'll go out on a limb and ask why you're using a UITextView. I honestly have never needed to use a UITextView. Try changing it to a UILabel and see if the problem is specific to the UITextView. If you absolutely need a UITextView, let me know in a comment, but I have a suspicion that a UILabel is what you're after.
It appears that you are adding it as a subview every time. So you're actually creating multiple UITextViews and adding them on top of each other. You would either need to removeFromSuperview or just set the text of the instance variable.
Take these two lines out of showMsg and put them in viewDidLoad:
[self setMessageTV : [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 315, 90 )]];
[self.view addSubview : [self messageTV]];
I have tried hiding a segmented controller just like a button or label can be hidden in XCode. It's intended to be hidden/shown when touching a parent segmented controller above. This Code would work with Buttons or Labels:
mySegmContr.hidden = YES;
But it just won't work for segmented controllers. Can you help me out?
I figured out that you can use a simple UIView in which you put the things you want to hide. The UIView can then be hidden with
myView.hidden = YES;
still I found no way to hide a segmented control directly.
If you create a property for the segment controller you can do more stuff with it like changing it's location, resizing it and want you want hiding it.
In your .h file do this
UISegmentedControl *mySegment;
#property (nonatomic, retain) UISegmentedControl *mySegment;
-(void) createMySegment;
In your .m file do this
#synthesize mySegment;
- (void) createMySegment {
if ([self mySegment] == nil) {
NSArray *buttons = [NSArray arrayWithObjects:#"One", #"Two", #"Three", nil];
UISegmentedControl *segName = [[UISegmentedControl alloc] buttons];
[self setMySegment:segName];
[segName release];
segName.frame = CGRectMake(110, 62, 120, 25);
segName.segmentedControlStyle = UISegmentedControlStyleBar;
segName.momentary = NO;
segName.selectedSegmentIndex = 0;
[segName addTarget:self
action:#selector(pickMethod:)
forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segName];
}
}
NOTE: With "setMySegment" above make sure you use a capital first letter which is M in "mySegment".
Then when you want to hide it use this. Don't for get to dealloc mySegment.
[[self mySegment] setHidden:YES];
I have created navigation based project. and in second screen i want to add uitabbarcontroller. so can any one suggest how i do this.
i already did lot of search but no success yet. so please can you provide a simple sample of this. i already tried below discussion but i think its not a good approach.
Navigation Based Application with TabBar
Thanks
Actually this is the correct approach. The one thing that is not correct is where the controllers are allocated. This is happened in the previous controller, the one that is making the push, but should be allocated in the object that is responsible, the TabBarController.
When you implement your action to show the UITabBarController make the following code:
- (void) theAction {
SomeTabBarControllerSubClass *controller = [[SomeTabBarControllerSubClass alloc] init];
[self.navigationController pushViewController:controller animated:YES];
[controller release];
}
Then when you implement the SomeTabBarControllerSubClass class:
(.h)
#interface SomeTabBarControllerSubClass : UITabBarController {
UIViewController *first;
UIViewController *second;
}
#end
(.m)
#implementation SomeTabBarControllerSubClass
- (void) viewDidLoad {
first = [[UIViewController alloc] init]; //Or initWithNib:
second = [[UIViewController alloc] init];
first.view.backgroundColor = [UIColor greenColor] //Just example
second.view.backgroundColor = [UIColor redColor] //Just example
first.tabBarItem.image = [UIImage imageNamed:#"someImage.png"];
self.viewControllers = [NSArray arrayWithObjects:first,second,nil];
}
- (void) dealloc {
[first dealloc];
[second dealloc];
[super dealloc];
}
#end
Hi Could you please let me know how to change the default colour of a tababar in Xcode i hav already tried this :
(void)viewDidLoad {
[super viewDidLoad];
UIImageView *img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"UITabBar.png"]];
img.frame = CGRectOffset(img.frame, 0, 1);
[tabBar1 insertSubview:img atIndex:0];
[img release];
but it doesnt work for me so can you please tel me in detail how can i change the colo
I know, this is an old thread, but nonetheless for all of you looking for an answer.
One of the ways to customize the look of UITabBar is to override drawRect: method with use of categories. Choose to create new file in your Xcode project, choose Objective-C category, then type UITabBar for Category On textfield. Next, declare drawRect: method in your category .h file and implement it in category .m file like this:
- (void)drawRect:(CGRect)rect {
UIImage *img = [UIImage imageNamed: #"tabbarBackground"];
[img drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
This will change the looks of all UITabBar instances in your app.
Hope this helps.
