commitAnimations is not resizing my UIImageView subview

Question

I have created a UIView as a subview and to that subview I have added a UIImageView as a subview.

UIView *viewCreated;
UIButton *buttonCreated;
UIImageView *imageViewCreated;
CGRect myFrame = CGRectMake(0, 0, 1024, 1024);
viewCreated = [[UIView alloc] initWithFrame:myFrame];
[viewCreated setTag:intTag];
viewCreated.backgroundColor = [UIColor redColor];
[self.view addSubview:viewCreated];
[self randomize];
UIImage *d1Image = [UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]];
imageViewCreated = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f,0.0f,1024.0f, 1024.0f)];
[imageViewCreated setImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]]; 
[viewCreated addSubview:imageViewCreated];
//[imageViewCreated release];
return [viewCreated autorelease];

But when this code executes only the first subview is animated and resized. The UiimageView moves 200 pixels to the left but does not get resized.

NSLog(@"sender tag %i",[sender tag]);   
UIView *currentView = [self.view viewWithTag:[sender tag]];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.5];  
currentView.frame = CGRectMake(-200, 0,40, 102);
[UIView commitAnimations];

I am pretty sure am I not creating the subviews correctly programmatically, because when I do it in Interface Builder it works as expected.

Do I have to do something specific to actually attach the behavior of the second subview to the first subview?

Answer 1

A few suggestions:

• Play with the contentMode property of the UIImageView. The default mode is UIViewContentModeScaleToFill. Something like UIViewContentModeScaleAspectFit may work better.

• Make sure somewhere in your code, you aren't accidentally setting the autoresizesSubviews property to NO.

• Instead of using frame sizing to scale the view, consider using the transform property and the CGAffineTransformMakeScale function. To make it move, you can also use CGAffineTransformMakeTranslation.

I ended up using this to resolve my problem. Worked perfectly.

imageViewCreated.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
