将TapGestureRecognizer添加到除UICollectionView单元格之外的整个视图

Question

我想添加一个TapGestureRecognizer来覆盖除UICollectionViewCell单元格之外的UICollectionViewController的整个屏幕。

我最接近的是

-(void) viewDidLoad {
...
UITapGestureRecognizer *tapAnywhere = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(addBoard:)];
[self.collectionView addGestureRecognizer:tapAnywhere];
}

问题：当我点击一个单元格时，不会调用prepareForSegue方法。 UITapGestureRecognizer似乎涵盖了单元格。

UICollectionViewController中哪个View是连接GestureRecognizer以保留其默认单元格“tap to segue”功能的正确方法？

Answer 1

实施手势识别器委托方法

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{
    if ([touch.view isKindOfClass:[UICollectionViewCell class]]) //It can work for any class you do not want to receive touch
    {
        return NO;
    }
    else 
    {
        return YES; 
    }
}
