indexView的tableViewCell

Question

我有一個自定義的方法來檢測單元格的圖像上的一個水龍頭。我也想找到圖像相關單元的索引路徑，並在函數內使用它。這裏是我使用的是什麼：

的cellForRowAtIndexPath：

UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(cellImageTapped:)]; 
tapped.numberOfTapsRequired = 1; 
[cell.imageView addGestureRecognizer:tapped]; 

方法，我嘗試在獲得索引路徑：

-(void)cellImageTapped:(id)sender { 
    if(videoArray.count > 0){ 
     Video *currentVideo = [videoArray objectAtIndex:INDEX_PATH_OF_CELL_IMAGE]; 
    //do some stuff   
    } 
} 

我不知道如何通過索引路徑。有任何想法嗎？

Answer 1

在您的UITableViewDataSource的tableView:cellForRowAtIndexPath:方法中爲UIImageView添加標籤。

cell.imageView.tag = indexPath.row; 

Answer 2

使用委託方法didSelectRowAtIndexPath方法：方法

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    [self cellImageTapped:indexPath]; 
} 

然後您可以將索引傳遞到即

-(void)cellImageTapped:(NSIndexPath *)indexPath 
{ 
    Video *currentVideo = [videoArray objectAtIndex:indexPath.row]; 
} 

Answer 3

我結束了使用發件人的視圖的標籤的功能。希望這會幫助某人，因爲我浪費了一小時才找到答案。

-(void)cellImageTapped:(id)sender { 

UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender; 

      if(videoArray.count > 0){ 
       NSInteger datIndex = gesture.view.tag; 
       Video *currentVideo = [videoArray objectAtIndex:datIndex]; 
      } 

} 

Answer 4

我會推薦這種方式來獲取其定製子視圖細胞indexPath - （與iOS 7以及以前所有版本兼容）

- (void)cellImageTapped:(UIGestureRecognizer *)gestureRecognizer 
{ 
    UIView *parentCell = gestureRecognizer.view.superview; 

    while (![parentCell isKindOfClass:[UITableViewCell class]]) { // iOS 7 onwards the table cell hierachy has changed. 
     parentCell = parentCell.superview; 
    } 

    UIView *parentView = parentCell.superview; 

    while (![parentView isKindOfClass:[UITableView class]]) { // iOS 7 onwards the table cell hierachy has changed. 
     parentView = parentView.superview; 
    } 


    UITableView *tableView = (UITableView *)parentView; 
    NSIndexPath *indexPath = [tableView indexPathForCell:(UITableViewCell *)parentCell]; 

    NSLog(@"indexPath = %@", indexPath); 
}

簡單的方法：

• 獲取觸摸點

• 然後在點獲得細胞的指數路徑

的代碼是：

-(void)cellImageTapped:(id)sender { 
    UITapGestureRecognizer *tap = (UITapGestureRecognizer *)sender; 
    CGPoint point = [tap locationInView:theTableView]; 

    NSIndexPath *theIndexPath = [theTableView indexPathForRowAtPoint:point]; 

    if(videoArray.count > 0){ 
     Video *currentVideo = [videoArray objectAtIndex:theIndexPath]; 
     //do some stuff 
    } 
}
