viewForHeaderInSection中的UISwipeGestureRecognizer

Question

我正在嘗試僅向表標題添加向左滑動識別。 似乎不起作用-嘗試了在stackoverflow和Web上找到的所有內容。 在實際的表格單元格上工作正常，但是將其添加到表格標題時……什么也沒有。

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

{SnapSong * song = nil;
NSString *文本= 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;

}

它只是不會滑動，我嘗試過在桌子上添加手勢等。

謝謝您的幫助

好吧，讓這個變戲法的東西起作用了

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

並且必須添加2個功能：

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

{返回是； }

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

當然，在.h文件中添加委托

@interface TableViewController : UIViewController<UIGestureRecognizerDelegate>
