//cell.otherID 是自定义 cell 属性

- (void)headImageViewClick:(UITapGestureRecognizer *)tap

{

//1, 通过获取所点击 cell 的属性获取 id 这种最靠谱

MsgCell *cell = (MsgCell *) [[tap.view.superviewsuperview]superview];

[self creatUserDetailViewWithID:cell.otherID];

//2, 通过 tap 手势获取 tag 获取, 但是tag 的 int 长度限制, 字段增加的话就不能用了

//cell.headImageView.tag = [cell.otherID integerValue];

// [self creatUserDetailViewWithID:[NSString stringWithFormat:@"%d",tap.view.tag]];

}

使用 lldb 工具打印:

1, tap.view获取当前点击的cell的详情

(lldb) po tap.view

<UIImageView: 0xbf1d140; frame = (10 30; 40 40); clipsToBounds = YES; opaque = NO; gestureRecognizers = <NSArray: 0xbf1d360>; layer = <CALayer: 0xbf1d1c0>>

2, tap.view.superview : 再次获取到的是 cellContentView

(lldb) po tap.view.superview

<UITableViewCellContentView: 0xbf1cc90; frame = (0 0; 320 378); gestureRecognizers = <NSArray: 0xbf1cea0>; layer = <CALayer: 0xbf1cd00>>

3,(lldb) po [tap.view.superview superview] :

<UITableViewCellScrollView: 0xbf1c820; frame = (0 0; 320 378); autoresize = W+H; gestureRecognizers = <NSArray: 0xbf1caa0>; layer = <CALayer: 0xbf1c9f0>; contentOffset: {0, 0}>

4,(lldb)po [[tap.view.superview superview] superview] 这样才能取出 cell 的属性

<MsgCell: 0xbf1c610; baseClass = UITableViewCell; frame = (0 602; 320 378); autoresize = W; layer = <CALayer: 0xbf1c7f0>>
