UIView(FWAutoLayout) Category Reference

fw_autoLayoutRTL
是否启用自动布局适配RTL，启用后自动将Left|Right转换为Leading|Trailing，默认NO

Note
如果项目兼容阿拉伯语等，需要启用RTL从右向左布局，开启此开关即可，无需修改布局代码手工切换视图左右布局方法：[UIView appearance].semanticContentAttribute = UISemanticContentAttributeForceRightToLeft;
Declaration
Objective-C

@property (class, nonatomic) BOOL fw_autoLayoutRTL;
fw_autoScale
是否全局自动等比例缩放布局，默认NO

Note
启用后所有offset值都会自动*relativeScale，注意可能产生的影响。启用后注意事项：
- 屏幕宽度约束不能使用screenWidth约束，需要使用375设计标准
- 尽量不使用screenWidth固定屏幕宽度方式布局，推荐相对于父视图布局
- 只会对offset值生效，其他属性不受影响
- 如需特殊处理，可以指定某个视图关闭该功能
Declaration
