剪切图像以适合图像视图

Question

I have a UIImageView with frame 320x240.

UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 240)];
imgView.image = [self getImageFromServer:100];

I have tried many ways bit no one resulted for me.

The app loads images from server, but some of them are 320x320.

What i must to cut the image received? It's to cut, does'n mater if someone is going to appear without head.

Regards

Answer 1

imgView.contentMode = UIViewContentModeScaleAspectFill;
imgView.clipsToBounds = true;

Answer 2

You can use the contentMode as Center if you want to keep always the size or you can resize untill it fits and then crop using the Scale Aspect Fit contend mode. You also need to clip the subviews.

You can do both actions via Interface Builder:

Setting the content mode:

Setting clip SubViews to YES:

Or programmatically:

//set the contentMode
imgView.contentMode = .contentMode = UIViewContentModeCenter;

//set clip subviews
test.clipsToBounds = YES;
