iphone - 当对象移动到特定帧时如何停止UIPanGestureRecognizer

我有一个图像类型的对象，我正在使用uipangestrerecognizer移动它，当对象到达某一帧时，我需要停止识别uipangestrerecognizer。

    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)];
    [panRecognizer setMinimumNumberOfTouches:1];
    [panRecognizer setMaximumNumberOfTouches:1];
    [panRecognizer setDelegate:self];
    [templatePhotoPlaceholderView addGestureRecognizer:panRecognizer];

-(void)move:(UIPanGestureRecognizer *)gestureRecognizer
{
    CGPoint translatedPoint = [gestureRecognizer translationInView:templatePhotoPlaceholderView];

    if([gestureRecognizer state] == UIGestureRecognizerStateBegan) {
        _firstX = [imageview center].x;
        _firstY = [imageview center].y;
    }



    translatedPoint = CGPointMake(_firstX+translatedPoint.x, _firstY+translatedPoint.y);
    //NSLog(@" Move center point :%@", NSStringFromCGPoint(translatedPoint));

    [imageview setCenter:translatedPoint];

}

我该怎么做？

最佳答案

uigestureRecognizers具有已启用的属性。文档：
禁用手势识别器，使其不接收触摸。这个
默认值为“是”。如果您将此属性更改为“否”
手势识别器当前正在识别一个手势
识别器转换到取消状态。
编辑：
只需将enabled属性设置为no。

gestureRecognizer.enabled = NO;
