iOS委托不会被调用

Question

我遇到了一个奇怪的问题，试图调用我的委托 - 它永远不会被调用。据我所知，委托永远不会被设置。我正在使用ARC。

CueCreateDelegate.h

#import <Foundation/Foundation.h>
@class CueCreateDelegate;
@protocol CueCreDelegate <NSObject>
    - (void)CueCreatedCall;
@end

@interface CueCreateDelegate : NSObject
@property (nonatomic, assign) id <CueCreDelegate> delegate;

-(void)CueCreated;
- (void) setdelegate:(id<CueCreDelegate>) delegates; //for testing
@end

CueCreateDelegate.m 从另一个类调用CueCreated并打印坏消息......

#import "CueCreateDelegate.h"

@implementation CueCreateDelegate
@synthesize delegate ;

- (void) setdelegate:(id<CueCreDelegate>) delegates{
        delegate = delegates;
}

-(void)CueCreated{
    if ([delegate respondsToSelector:@selector(CueCreatedCall)]) {
        [delegate CueCreatedCall];
    }
    else{
        NSLog(@"Delegate method not getting called...%@",delegate);
    }

}
@end

MatrixViewController.h

#import <UIKit/UIKit.h>
#import "CueCreateDelegate.h"

@interface MatrixViewController : UIViewController<UIGestureRecognizerDelegate,CueCreDelegate>{
    CueCreateDelegate *cueCre;
}

MatrixViewController.m 永远不会调用CueCreatedCall ..

-(void)CueCreatedCall{
    NSLog(@"lsakdlakjdlks");
}


- (void)viewDidLoad
{

  cueCre = [[CueCreateDelegate alloc] init];

   // [cueCre setdelegate:self];
    [cueCre setDelegate:self];
    NSLog(@"%@",[cueCre delegate]);

}
