Yes, I dragged the file to my project, then after I compiled the project, it had an error report "Returning block that lives on the local stack" in MASCompositeConstraint.m in line 52 return ^id(CGFloat multiplier)
I finally found that it's related to ARC,if I set Objective-C Automatic Reference Counting NO, this error appear
