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. Or drag ImageMenuItem.xcodeproj to your project and embed ImageMenuItem framework if you only support iOS 8.0 and above.
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)initWithTitle:(NSString *)title action:(SEL)action image:(UIImage *)image;
- (id)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, strong) UIColor * __nullable shadowColor; // Default is [[UIColor blackColor] colorWithAlphaComponent:1./3.]
@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.
