本文介绍如何在iOS应用中使用Objective-C实现带有特定圆角的UIImageView。通过设置CAShapeLayer并结合UIBezierPath，可以精确控制UIImageView的圆角位置及大小。

UIImage *image = [UIImage imageNamed:@"000.tiff"];

UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(50, 50, 320, 328)];

imgView.contentMode = UIViewContentModeScaleAspectFill;

imgView.image = image;

[self.view addSubview:imgView];

CAShapeLayer *shapeLayer = [CAShapeLayer layer];

shapeLayer.backgroundColor = [UIColor clearColor].CGColor;

shapeLayer.path = [UIBezierPath bezierPathWithRoundedRect:imgView.bounds byRoundingCorners:UIRectCornerBottomRight cornerRadii:CGSizeMake(100.0, 100.0)].CGPath;

imgView.layer.masksToBounds = YES;

imgView.layer.mask = shapeLayer;

shapeLayer.frame = imgView.layer.bounds;
