未调用委托方法: IOS 6

Question

我有一个ConfirmClaimViewcontroller.h，它将委托定义为：

@protocol ClaimConfirmedDelegate<NSObject>
@required
- (void) claimConfirmedDelegate : (NSInteger) tag;
@end

@interface ConfirmClaimControllerViewController : UIViewController{
    id <ClaimConfirmedDelegate> delegate;
}

-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil withTag:(NSInteger)tag;

@property(nonatomic,assign)id delegate;

@end

我在ClaimViewController.m中定义了委托：

- (void) claimConfirmedDelegate:(NSInteger)tag{
    NSLog(@"Delegate called");
}

我按以下方式调用ConfirmClaimViewController (它是一个弹出窗口)：

   ConfirmClaimControllerViewController *confirmClaimController=[[ConfirmClaimControllerViewController alloc] initWithNibName:@"ConfirmClaim" bundle:nil withTag:sender.view.tag];
    confirmClaimController.delegate = self;
    [self.view addSubview:confirmClaimController.view];
    [confirmClaimController didMoveToParentViewController:self];
    [self addChildViewController:confirmClaimController];

弹出式窗口有两个按钮。其中一个按钮被单击，此代码称为：

if([self.delegate respondsToSelector:@selector(claimConfirmed:)])
{
    [self.delegate claimConfirmedDelegate:self.tagId];
}


[self.view removeFromSuperview];
[self removeFromParentViewController];

这应该是调用委托方法，然后将子对象从视图中删除。子对象被移除，但从来不调用委托。我是新手，任何帮助都将不胜感激。

Answer 1

这一行：

if([self.delegate respondsToSelector:@selector(claimConfirmed:)])

应：

if([self.delegate respondsToSelector:@selector(claimConfirmedDelegate:)])
