UIMenuItem uses UILabel to display its title, that means we can swizzle -drawTextInRect: to support image.
UIMenuItem+CXAImageSupport is a dirty hack but should be safe in most cases. Contains no any private APIs and should be safe for App Store.
Drag UIMenuItem+CXAImageSupport.{h,m} to your project.
The method names describe all. For simple usage, the only step is to set a image to the menu item. For advance usage, config and set a settings.
@class CXAMenuItemSettings;
@interface UIMenuItem (CXAImageSupport)
- (id)cxa_initWithTitle:(NSString *)title action:(SEL)action image:(UIImage *)image;
- (id)cxa_initWithTitle:(NSString *)title action:(SEL)action settings:(CXAMenuItemSettings *)settings;
- (void)cxa_setImage:(UIImage *)image;
- (void)cxa_setSettings:(CXAMenuItemSettings *)settings;
@end
// Uses a settings class instead of NSDictionary to avoid
misspelled keys
@interface CXAMenuItemSettings : NSObject
+ (instancetype)settingsWithDictionary:(NSDictionary *)dict;
@property (nonatomic) UIImage *image;
@property (nonatomic) BOOL shadowDisabled;
@property (nonatomic) CGFloat shrinkWidth; // For adjustment item width only,
will not be preciouse because menu item will keep its minimun width,
it's useful for showing some large amount of menu items without expanding.
@end
UIMenuItem+CXAImageSupport uses UIMenuItem's title to map related image since there is no any other clue of UIMenuItem I can find to connect to UILabel. You can't set different images for the same title.
