「AnyDo」刷卡刪除動畫

Question

我想實現刷卡上表視圖刪除單元格象是在AnyDo應用。任何幫助？

我的代碼：

我使用的是手勢識別

 - (UISwipeGestureRecognizer *)swipeRightRecognizer 
     { 
     if (!_swipeRightRecognizer) 
      { 
      _swipeRightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)]; 
      _swipeRightRecognizer.direction = UISwipeGestureRecognizerDirectionRight; 
     } 

     return _swipeRightRecognizer; 
     } 

添加手勢細胞：

 [cell.contentView addGestureRecognizer:self.leftGestureRecognizer]; 

處理刷卡。

 - (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer indexPath: (NSIndexPath *)index 
     { 
     if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) 
     { 
     //Table View deletion code. + Line to be drawn on cell, move that cell to the bottom of the table with animaiton. 
     } 

}

科林Eberhardt寫了一個偉大的教程How to Make a Gesture-Driven To-Do List App Like Clear。滑動刪除funcionality也是成功的。

Answer 2

您可以使用UISwipeGestureRecognizer。

UISwipeGestureRecognizer *gRec = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(yourSelector:)]; 
[gRec setDirection:(UISwipeGestureRecognizerDirectionRight | UISwipeGestureRecognizerDirectionDown | UISwipeGestureRecognizerDirectionLeft | UISwipeGestureRecognizerDirectionUp)]; 

[yourCell addGestureRecognizer:gRec]; 

在yourSelector方法可以處理輕掃：

- (void)yourSelector:(id)sender { 
    NSLog(@"Handle swipe"); 
    UISwipeGestureRecognizer *gRec = sender; 
    UITableViewCell *cell = [gRec view]; 

    UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(x,y,0,0)]; 
    [line setImage:[UIImage imageNamed:@"line.png"]]; 
    [UIView animateWithDuration:0.3 animation:^ (void) { 
     [cell addSubview:line]; 
     [line setFrame:CGRectMake(x,y,320,5]; 
    } completion:nil]; 
} 

編輯： 我添加了一行代碼，但我不能現在就試試吧。然而，它應該工作
