问题
I'm trying to make a UIImageView with round corners, so I used [imageView.layer setCornerRadius:5.0f]; it works but not perfectly.
If you look closely, you can see the corners of the image(I uploaded a photo, I don't know if you can see it clearly, there are blue parts in the corners). How should I remove these? thank you.
(P.S.: I also set the border of the view, is that the reason why?)
回答1:
UIImageView doesn't clip to bounds by default. So while the corner radius is applied its still drawing outside of its designated area.
objc:
[imageView setClipsToBounds:YES];
swift:
imageView.clipsToBounds = true
