Question

我正在尝试仅向表格标题添加滑动左侧识别。似乎没有工作 - 尝试在stackoverflow和web上找到的一切。在实际的表格单元格上工作得很好，但是当它添加到表格标题时......没有。

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

{ SnapSong * song = nil;
NSString * text = song.title; NSString * detailedText = song.albumName;

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 80)];
view.backgroundColor = [[Globals sharedInstance] gCellBgColor];
view.tag = section;
UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                                                 action:@selector(handleSwipeLeft:)];
[recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
[view addGestureRecognizer:recognizer];

return view;

}

它只是不会滑动，我尝试在桌面上添加手势等...

感谢您的帮助

好的，让精力充沛的事情发挥作用，这就是诀窍

 UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                                                 action:@selector(handleSwipeLeft:)];
**[recognizer setDelegate:self];**
[recognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
[view addGestureRecognizer:recognizer];

并且必须添加2个功能：

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

{ 返回YES; }

（BOOL）gestureRecognizerShouldBegin：（UIGestureRecognizer *）gestureRecognizer { 返回YES; }

当然在.h文件中添加委托

@interface TableViewController : UIViewController<UIGestureRecognizerDelegate>

viewForHeaderInSection中的UISwipeGestureRecognizer
