Circular UIImageView in UITableView without performance hit?
ios, objective-c, uiimageview, uitableview
Solution
Simply set the `cornerRadius` to half of the width or height (assuming your object's view is square).
For example, if your object's view's width and height are both 50:
itemImageView.layer.cornerRadius = 25;
Update - As user atulkhatri points out, it won't work if you don't add:
itemImageView.layer.masksToBounds = YES;
Problem
I have a `UIImageView` on each of my `UITableView` cells, that display a remote image (using `SDWebImage`). I've done some `QuartzCore` layer styling to the image view, as such: ``` UIImageView *itemImageView = (UIImageView *)[cell viewWithTag:100]; itemImageView.layer.borderWidth = 1.0f; itemImageView.layer.borderColor = [UIColor concreteColor].CGColor; itemImageView.layer.masksToBounds = NO; itemImageView.clipsToBounds = YES; ``` So now I have a 50x50 square with a faint grey border, but I'd like to make it circular instead of squared. The app `Hemoglobe` uses circular images in table views, and that's the effect I'd like to achieve. However, I don't want to use `cornerRadius`, as that degrades my scrolling FPS. Here's `Hemoglobe` showing circular `UIImageViews`: Is there any way to get this effect? Thanks.
