我的代表:
@class UpdateUserSummary;
@protocol UpdateSummaryDelegate <NSObject>
- (void)updateSummaryDidCancel:(UpdateUserSummary*)controller;
- (void)updateSummaryDone:(UpdateUserSummary*)controller;
@end
在界面:
@interface UpdateUserSummary : UIViewController
@property (nonatomic, weak) id<UpdateSummaryDelegate> delegate;
@end
- (IBAction)done:(id)sender {
[self.delegate updateSummaryDidCancel:self];
}
代表回复:
-(void)updateSummaryDidCancel:(UpdateUserSummary *)controller
{
// just close modal vc
[self dismissViewControllerAnimated:YES completion:nil];
}

使用这个, UpdateUserSummary.delegate = self; 你在实现类中调用delegate的地方。
答案 1 :(得分:1)
@protocol MUpdateSummaryDelegate;
@interface MUpdateSummary : NSObject
@property (assign) id<UpdateSummaryDelegate> delegate; //You need this
@end
@protocol UpdateSummaryDelegate <NSObject>
-(void)updateSummaryDidCancel:(UpdateUserSummary *)controller;
@end
在您调用委托的类中,您需要设置委托。
MUpdateSummary *mUpdateSummary = [[MUpdateSummary alloc] init];
mUpdateSummary.delegate = self;
