iOS layer.borderWidth

Question

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(100,100,100,100)];
view.backgroundColor = [UIColor redColor];
view.layer.borderWidth = 1.0;
view.layer.borderColor = [UIColor blueColor].CGColor;
UIImageView *image = [[UIImageView alloc]initWithFrame:CGRectMake(-8, -10, 20, 20)];
image.image = [UIImage imageNamed:@"sample"];
[view addSubview:image];

图像在视图中，但边界线是透明的···请告诉我如何解决此问题。

Answer 1

尝试使用：

image.clipsToBounds = YES;

Answer 2

 image.contentMode = UIViewContentModeScaleAspectFit;

添加上面一行的code.Issue将会被解析。
