Iphone ui打开/关闭ui长按手势识别器的开关

我在我的应用程序中声明了以下方法，我想在我的mapView中实现一个开关来打开和关闭

ui长按GestureRecognitizer

- (IBAction)addNewPin:(UISwitch *)sender {

if (sender.on) {

NSLog(@"ON!!");
}

else {

NSLog(@"OFF!!");
}

}


- (IBAction)didPressForPin:(UILongPressGestureRecognizer *)sender {

CGPoint point = [sender locationInView:self.mapView];
CLLocationCoordinate2D locCoord = [self.mapView convertPoint:point toCoordinateFromView:self.mapView];

MKPointAnnotation *pa = [[MKPointAnnotation alloc]init];
pa.coordinate = locCoord;
pa.title = @"Test Title!";
[mapView addAnnotation:pa];


NSLog(@"Pressed!!");


}

我知道我可以添加或删除手势识别器或实现

。enabled=NO

，但我不知道如何在switch方法中实现它。

假设您拥有

LongPressGestureRecognitor

属性，类似的内容可能会有所帮助：

@synthesize longPressGestureRecognizer = _longPressGestureRecognizer;

- (UILongPressGestureRecognizer *)longPressGestureRecognizer
{
    if (_longPressGestureRecognizer) {
        return _longPressGestureRecognizer;
    }

    _longPressGestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPressGesture:)];
    return _longPressGestureRecognizer;
}


- (IBAction)toggleAddPinSwitch:(UISwitch *)sender
{
    if ([sender isOn]) {
        [self.mapView addGestureRecognizer:self.longPressGestureRecognizer];
    } else {
        [self.mapView removeGestureRecognizer:self.longPressGestureRecognizer];
    }
}

这个问题与“Xcode 4.5”有什么关系？你99%都在那里，我不确定你不知道该怎么做？谢谢，这很有效。我刚刚在ViewDidLoad中添加了“\u LongPressGestureRecognitizer=[[UILongPressGestureRecognitizer alloc]initWithTarget:self action:@selector（HandleLongPress手势：）]；return _LongPressGestureRecognitizer；”，以便使用我的触摸定位方法。很高兴听到这个消息。快乐编码。
