Ios – UIImageView _isResizable: Unrecognized Selector

compiler-errorsiosiphoneobjective cuiimageview

I have the following code to display an image on a brand but I get an UIImageView error.
I resize my image of size 800×600 to fit to the size of the screen of the iPhone.

NSURL * url = [NSURL URLWithString:@"http://www.portallzc.com/galerias/galeria_Portal%20de%20Lazaro%20Cardenas/Club%2033/800/p16jklq9uj1f7a1c6tckkjrg1i8015.JPG"];
NSData * urlData = [NSData dataWithContentsOfURL: url];
UIImage * image = [UIImage imageWithData: urlData];
CGRect rect = CGRectMake (0.0f, 40.0f, image.size.width, image.size.height);

image = [[UIImageView alloc] initWithFrame: rect];
[setImage image: image];

Error: Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '- [UIImageView _isResizable]:
unrecognized selector instance stmt to 0x6b8bb70'

Best Answer

The Error occur because you attempt to treat UIImageView as an UIImage.

myImageView = [[UIImageView alloc] initWithFrame: rect];
[myImageView setImage: image];

If the error disappear try to check

[self.view addsubview:myImageView];

to make your imageview link to display screen.

If it still not appear try to check layer of your image view.

[self.view bringSubviewToFront:myImageView];

IPhone – Splash Screen with progress bar

As mentioned in another answer, for some finite amount of time, as your app is being launched, Default.png is displayed and you have no control over it. However, if in your AppDelegate, you create a new view that displays the same Default.png, you can create a seamless transition from the original Default.png to a view that you can add a progress bar to.

Now, presumably, you have created a view or similar and you are updating a progress bar every so often in order to give the user some feedback. The challenge here is that your view is only drawn when it gets called to do a drawRect. If, however, you go from AppDelegate to some initialization code to a viewcontroller's viewDidLoad, without the run loop getting a chance to figure out which views need to have drawRect called on, then your view will never display its status bar.

Therefore in order to accomplish what you want, you have to either make sure that drawRect gets called, such as by pushing off a lot of your initialization code into other threads or timer tasks, or you can force the drawing by calling drawRect yourself, after setting up contexts and such.

If you go with the background tasks, then make sure your initialization code is thread-safe.

Ios – UIGestureRecognizer on UIImageView

Check that userInteractionEnabled is YES on the UIImageView. Then you can add a gesture recognizer.

imageView.userInteractionEnabled = YES;
UIPinchGestureRecognizer *pgr = [[UIPinchGestureRecognizer alloc] 
    initWithTarget:self action:@selector(handlePinch:)];
pgr.delegate = self;
[imageView addGestureRecognizer:pgr];
[pgr release];
:
:
- (void)handlePinch:(UIPinchGestureRecognizer *)pinchGestureRecognizer
{
  //handle pinch...
}
