ios - 满足特定条件时检测 LongPress

Question

我在我的集​​合 View 中使用 UILongPressGestureRecognizer，我希望长按手势识别器只有在满足特定条件时才能工作。

NSString *check;
if([check isEqualToString:@"Enabled"]
{
    //long press should be detected. or following method should be called
}

-(void)handleLongPressGesture:(UILongPressGestureRecognizer *)gestureRecognizer

{
}

Answer 1

添加 UIGestureRecognizerDelegate

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{

    NSString *check;
    if([check isEqualToString:@"Enabled"]
    {
        //long press should be detected. or following method should be called
        return YES;
    }else{
        return NO;
    }
}
