長按手勢調用兩次問題解決

今天遇到一個問題。就是給了個長按手勢，然後調用方法，但是總是調用兩次，第二次調用，會使我的方法崩潰，找了好久才找到。

 UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressGuesture:)];

    longPress.minimumPressDuration = 1.0;

    longPress.delegate = self;

    longPress.delaysTouchesBegan = YES;

    longPress.numberOfTouchesRequired = 1;

    [_collectionView addGestureRecognizer:longPress];

- (void)handleLongPressGuesture:(UILongPressGestureRecognizer *)guesture{

    

    if (guesture.state == UIGestureRecognizerStateBegan) {

        NSLog(@"開始");

        CGPoint point = [guesture locationInView:_collectionView];

        

        NSIndexPath *indexpath = [_collectionView indexPathForItemAtPoint:point];

        UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

        //    NSString *tempStr = [self.dataSouce[indexpath.section - 1][indexpath.row] objectForKey:@"imgUrl"];

        NSString *tempStr = [self.dataSouce[indexpath.section - 1][indexpath.row] objectForKey:@"imgUrl"];

        NSLog(@"打印內容%@",tempStr);

        

        pasteboard.string = tempStr;

        

        if (pasteboard.string.length)

        {

            [KyoUtil showAlertWithString:@"複製成功"];

        }else{

            [KyoUtil showAlertWithString:@"複製失敗"];

        }  

    }else{

        NSLog(@"結束");

       

    }

    

    

}

解決方法就是在長按方法裏面，判斷touch的狀態
