constraint - note that buttons in demo constructed to work with UIImageView. UIButton for logic, and UIImageView to represent button image i.e. facebook or twitter logo - background color of CustomView and UIView that holds UIButton and UIImageView has transparent color thus badges from normal buttons can be properly showed In short, it will work like before and no need to worry about different usage. What added is taking care and handle for the case if user construct UI element with .xib and in programmatically way with dynamic constraint. See the demo code for example.

I found a problem of badge doesn't show when I have a button which is
MIBadgeButtonunder a customUIViewfrom.xib, and when create an instance from that view, use programmatic way in creating constraints dynamically.Thus this merge fixed this problem, and still respect the original way of positioning badge via modifying
frame. It will check in view hierarchy first whether it needs to apply such solution or not.The solution creates constraints dynamically to position badge properly and accordingly, and also use calculated values from original method too for performance.
Demo sample (also included in this merge) will be like this now
The first row shows when use
.xiband dynamic constraints.The second row shows original and normal approach.
Edit:
This is against
swift2. I can contribute forswift3thusmasterbranch later when this merge is accepted and merged.
