UIImageView change Width and Height

Question

I\'ve read various posts on here asking similar questions... I\'ve tried various ways that were posted including bounds and frames etc. including the following:

First off, you can't set the frame or bounds of the UIImage - that will only work on a UIImageView.

I've found that changing the frame of a UIImageView causes the Image to be scaled to the new size. Sometimes, that's undesirable - and you want instead to crop the image.

I can't tell if this is what you're asking for, but here's some code to crop an image to a specific size in a UIImageView:

UIImage *myImage = [UIImage imageNamed:@"photo.png"];

CGRect cropRect = CGRectMake(0.0, 0.0, 320.0, 44.0));
CGImageRef croppedImage = CGImageCreateWithImageInRect([myImage CGImage], cropRect);

UIImageView *myImageView = [[UIImageView alloc] initWithFrame:cropRect];
[myImageView setImage:[UIImage imageWithCGImage:croppedImage]]; 

CGImageRelease(croppedImage);
