使用Autolayout时, viewDidLoad中自动布局还没有执行, 所以不能获取实际宽高 可以在viewDidLoad, viewDidLayoutSubviews, layoutSubviews中获取
或者获取屏幕宽高自己算
[[[UIApplication sharedApplication] keyWindow] bounds] [[[[UIApplication sharedApplication] delegate] window] bounds] [[UIScreen mainScreen] bounds]
修改约束不能在viewDidLoad中, viewDidLoad中设置后xib会覆盖回来. 需要延迟修改
xib Size 需要设置成Freeform
