问题描述
收到警告消息,忽略ModalViewDelegate的重复协议定义
modalviewcontroller.h文件中定义的协议
@protocol ModalViewDelegate;
- (void)dismissView:(id)sender;
@interface Modalviewcontroller:UIViewController
{
id< ModalViewDelegate> delegate;
}
@property(nonatomic,assign)id< ModalViewDelegate> delegate;
@end
在Modalviewcontroller.m文件中合成代理
在Mainviewcontroller.h文件中
@protocol ModalViewDelegate
- (void)didDismissModal: (ID)发送者;
@end
@interface Mainviewcontrollerontroller:UIViewController< ModalViewDelegate>
- (void)showModal:(id)sender;
在Mainviewcontroller.m中没有合成代理
为什么我收到重复协议定义的警告消息?
尝试在 modalviewcontroller.h中删除
并在此文件中导入 @protocol ModalViewDelegate;
Mainviewcontroller.h
。
Getting warning message that Duplicate protocol definition of ModalViewDelegate is ignored
Defined protocol in modalviewcontroller.h file
@protocol ModalViewDelegate;
-(void)dismissView:(id)sender;
@interface Modalviewcontroller : UIViewController
{
id<ModalViewDelegate>delegate;
}
@property (nonatomic, assign) id<ModalViewDelegate>delegate;
@end
In the Modalviewcontroller.m file synthesize delegate
In Mainviewcontroller.h file
@protocol ModalViewDelegate
-(void)didDismissModal:(id)sender;
@end
@interface Mainviewcontrollerontroller : UIViewController <ModalViewDelegate>
-(void)showModal:(id)sender;
In the Mainviewcontroller.m not synthesize delegate
Am I supposed to delegate in mainviewcontroller.m file too?
Why I'm getting warning message of duplicate protocol definition?
Try to remove @protocol ModalViewDelegate;
in modalviewcontroller.h
and import Mainviewcontroller.h
in this file.
