iphone - 更改枚举类型值

Question

您好，我正在使用图书馆。它有一些嵌入在枚举中的选项，但我不知道如何配置它们。该库称为PPRevealSideViewController。
它具有一个属性:

@property (nonatomic, assign) PPRevealSideOptions options;

这是枚举代码:

enum {
    PPRevealSideOptionsNone = 0,
    PPRevealSideOptionsShowShadows = 2 << 1, /// Disable or enable the shadows. Enabled by default
    PPRevealSideOptionsBounceAnimations = 1 << 2, /// Decide if the animations are boucing or not. By default, they are
    PPRevealSideOptionsCloseCompletlyBeforeOpeningNewDirection = 1 << 3, /// Decide if we close completely the old direction, for the new one or not. Set to YES by default
    PPRevealSideOptionsKeepOffsetOnRotation = 1 << 4, /// Keep the same offset when rotating. By default, set to no
    PPRevealSideOptionsResizeSideView = 1 << 5, /// Resize the side view. If set to yes, this disabled the bouncing stuff since the view behind is not large enough to show bouncing correctly. Set to NO by default
};
typedef NSUInteger PPRevealSideOptions;

非常感谢你!

Answer 1

obj.options = opt0 | opt1 | ... etc

例如: obj.options = PPRevealSideOptionsBounceAnimations | PPRevealSideOptionsResizeSideView;
