Question

我有一个带有表视图的视图控制器。每个单元格都有一个带五星评级系统的自定义视图。我在视图的类中处理视图的touchesBegan

    - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    CGPoint touchLocation = [touch locationInView:self];
    [self handleTouchAtLocation:touchLocation];

}

如何获取indexPath以了解哪个用户投票？我没有按钮我有一个uiview所以我不能使用以下内容：

CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];

Answer 1

做一件事

在索引路径

的行中为单元格内的视图提供手势

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tappedOnView:)];
[singleTap setNumberOfTapsRequired:1];
[singleTap setNumberOfTouchesRequired:1];
[viewnanme addGestureRecognizer:singleTap];

并处理点击手势

-(void)tappedOnView:(UITapGestureRecognizer *)gesture
{
CGPoint location = [gesture locationInView:tableView];
NSIndexPath *ipath = [tableView indexPathForRowAtPoint:location];
UITableViewCell *cellindex  = [tableView cellForRowAtIndexPath: ipath];
}

Swift 3+

var singleTap = UITapGestureRecognizer(target: self, action: #selector(self.tappedOnView))
singleTap.numberOfTapsRequired = 1
singleTap.numberOfTouchesRequired = 1
viewnanme.addGestureRecognizer(singleTap)


func tapped(onView gesture: UITapGestureRecognizer) {
    let location: CGPoint = gesture.location(in: tableView)
    let ipath: IndexPath? = tableView.indexPathForRow(at: location)
    let cellindex: UITableViewCell? = tableView.cellForRow(at: ipath!)
}

Swift 4 +

var singleTap = UITapGestureRecognizer(target: self, action: 
#selector(self.tappedOnView))
singleTap.numberOfTapsRequired = 1
singleTap.numberOfTouchesRequired = 1
viewnanme.addGestureRecognizer(singleTap)

func tapped(onView gesture: UITapGestureRecognizer) 
{
    let location: CGPoint = gesture.location(in: tableView)
    let ipath: IndexPath? = tableView.indexPathForRow(at: location)
    let cellindex: UITableViewCell? = tableView.cellForRow(at: ipath ?? 
 IndexPath(row: 0, section: 0))
}

希望这会对你有所帮助。：）

Answer 2

在cellforAtIndexPath中将视图的标记保留为indexPath.row，并在以下方法中

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

根据该视图标记

获取UItableViewCell

Answer 3

通过在视图的类中创建属性，可以在cellForRowAtIndexPath:中创建视图时将索引路径存储在自定义视图中。可以在init中为自定义视图设置该属性。然后，通过阅读属性，您的touchesBegan:withEvent:方法将可以使用索引路径。

Answer 4

UITableView有一个给定的委托方法，即cellForRowIndexPath：。您无需在代码中添加任何Tap Gesture或touchesBegan：方法。 TableView已经有了这个。您可以在此方法cellFor RowIndexPath中获取所选单元格的索引路径：。
