使用Masonry遇到的错误

错误原因：

在使用自动布局时，不断的报下面的错误：Unable to simultaneously satisfy constraints.Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) (    "",    "",    "",    "",    "")Will attempt to recover by breaking constraintBreak on objc_exception_throw to catch this in the debugger.The methods in the UIConstraintBasedLayoutDebugging category on UIView listed inmay also be helpful.

可能出错原因：

1，你的约束的确设置错误；

2，忘记设置控件的：setTranslatesAutoresizingMaskIntoConstraints 等于NO 。

3，骚年，快回头看看你的代码，是不是哪里手懒，没用alloc初始化，用的是new啊，改回alloc初始化控件即可。
