How can i set a background image in a UIAlertView progrmatically?
There is no method to set the background image for AlertView. We need to set image as subView for alert View.
Try this way it will work:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"Message 1......\nMessage 2......" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
UIImageView *Image =[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"ImageName"]];
[alert addSubview:Image];
[Image release];
[alert show];
[alert release];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"title" message:#"Empty data not Allowed" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
UIImage *alertImage = [UIImage imageNamed:#"custom-dialog-background.png"];
UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:alertImage];
backgroundImageView.frame = CGRectMake(0, 0, 282, 130);
backgroundImageView.contentMode = UIViewContentModeScaleToFill;
[alert addSubview:backgroundImageView];
[alert sendSubviewToBack:backgroundImageView];
[alert show];

So far I am able to save an image from the web view that is (768,3000); to my camera roll but it cuts off any of the web view's content that isn't currently showing on the screen?
-(IBAction)capturaScreenButton:(id)sender
{
UIAlertView *alert;
CGSize sixzevid=CGSizeMake(768,3000);
CGSize size = [webView sizeThatFits:CGSizeZero];
UIGraphicsBeginImageContextWithOptions( size, YES, 0.0);
UIGraphicsBeginImageContext(sixzevid);
//UIGraphicsBeginImageContextWithOptions(self.webView.bounds.size, self.webView.opaque, 0.0);
[self.webView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
alert = [[UIAlertView alloc] initWithTitle:#"Image captured by Me"
message:#"The image is in your Photo Album..."
delegate:self cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alert show];
[alert release];
UIGraphicsEndImageContext();
}
I am new to IOS now I am developing location app i am not getting correct latitude,longitude values while running my app in iPhone.. it gives me too far lat,long values to the current location why it shows me these values can anyone tell me..
Try it....
Set Delegate CLLocationManagerDelegate
#import <CoreLocation/CoreLocation.h>
CLLocationManager *locationManager;
CLLocation *startLocation;
- (void)viewDidLoad {
[super viewDidLoad];
NSString *currentLatitude;
NSString *currentLongitude;
locationManager = [[CLLocationManager alloc] init];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.delegate = self;
[locationManager startUpdatingLocation];
startLocation = nil;
}
-(void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
currentLatitude = [[NSString alloc]
initWithFormat:#"%g",
newLocation.coordinate.latitude];
currentLongitude = [[NSString alloc]
initWithFormat:#"%g",
newLocation.coordinate.longitude];
NSLog(#"%#",currentLatitude);
NSLog(#"%#",currentLongitude);
}
-(void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"ERROR" message:[NSString stringWithFormat:#"%#",error] delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
I have the following code that displays the alerts depending on the result: How can I improve the following code:
-(IBAction)saveSettings:(id)sender
{
UIAlertView *alert = nil;
username = self.usernameTextField.text;
token = self.passwordTextField.text;
// validate the username and token
if(![self isValid])
{
// show alert that it is not valid
alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Invalid User Name or Password" delegate:self cancelButtonTitle:nil otherButtonTitles:#"Ok", nil];
[alert show];
return;
}
BOOL isSynched = [self syncSettings];
if(!isSynched)
{
alert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Error Syncing Settings" delegate:self cancelButtonTitle:nil otherButtonTitles:#"Ok", nil];
[alert show];
}
else
{
alert = [[UIAlertView alloc] initWithTitle:#"" message:#"Settings has been Synced Syncing" delegate:self cancelButtonTitle:nil otherButtonTitles:#"Ok", nil];
[alert show];
}
}
I think I am instantiating the alert too many times and looks kind of repetitive!
username = self.usernameTextField.text;
token = self.passwordTextField.text;
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#""
delegate:self
cancelButtonTitle:nil
otherButtonTitles:#"Ok", nil];
[alert autorelease];
// validate the username and token
if(![self isValid])
{
// show alert that it is not valid
alert.message = #"Invalid User Name or Password";
[alert show];
return;
}
BOOL isSynched = [self syncSettings];
if(!isSynched)
{
alert.message = #"Error Syncing Settings";
}
else
{
alert.title = #"";
alert.message = #"Settings has been Synced Syncing";
}
[alert show];
Try leaving all those instances of [alert show]; out & then at the end put...
if (!alert) return;
[alert show];
phix23's answer also provides good improvement because you're setting a bunch of the properties of the alert explicitly & only once. If you use that you can also use mine by changing the condition to...
if (alert.message != #"") return;
Cheers, Pedro :)

I am working on orientation of actionsheet with pickerview. It is working finely on potrait mode but it is not working on landscape mode. May I know where i went wrong?

[barItems release];
[pickerViewPopup addSubview:pickerToolbar];
[pickerViewPopup addSubview:m_pickerView];
//[pickerViewPopup addSubview:pickerImageView];

}
If you are not adding your UIActionSheet to a view controller that is handling the orientation for landscape, then the UIActionSheet will come up in portrait.
