You can crop your image with a shapelayer. To do it you have to create a path that will be used as borders for your new image. You should look at this question.

CALayer* contentLayer = [CALayer layer];
[contentLayer setFrame:CGRectMake(0, 0, 80, 80)];
CAShapeLayer* mask = [CAShapeLayer layer];

CGMutablePathRef path = CGPathCreateMutable();

CGPathMoveToPoint(path, NULL, 10, 10);
CGPathAddLineToPoint(path, NULL, 10, 80);
CGPathAddLineToPoint(path, NULL, 80, 80);
CGPathAddLineToPoint(path, NULL, 80, 10);
mask.path = path;

[contentLayer setContents:(id)[[UIImage imageNamed:@"image.png"] CGImage]];
[contentLayer setMask:mask];          

[[self layer]addSublayer:contentLayer];

Something like this.
