uiscrollview 不会取消 uisegmentedcontrol 的内容触摸

我已经对 UIScrollView 进行了子类化，并按以下方式重写了 TouchesShouldCancelInContentView: 方法：

-(BOOL)touchesShouldCancelInContentView:(UIView *)view

{
    if ([view isKindOfClass:[UIButton class]] || [view isKindOfClass:[UISegmentedControl class]]) {
        return YES;
    }

    if ([view isKindOfClass:[UIControl class]]) {
        return NO;
    }

    return YES;
}

它非常适合 UIButton，但不适用于 UISegmentedControl。任何帮助，将不胜感激

终于想通了。必须对 UISegmentedControl 和 UIScrollView 进行子类化。

1.) 为 UISegmentedControl 添加了一个新属性：

@property (nonatomic, assign) BOOL touchProcessed;

2.) 重载了 UISegmentedControl 的以下方法：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (touchProcessed) {
        [super touchesBegan:touches withEvent:event];
    }
    else {
        [self.nextResponder touchesBegan:touches withEvent:event];
    }
    self.touchProcessed = NO;
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.nextResponder touchesMoved:touches withEvent:event];
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.nextResponder touchesEnded:touches withEvent:event];
}

3.) 重载了 UIScrollview 的以下方法：

-(BOOL)touchesShouldCancelInContentView:(UIView *)view
{ 
    if ([view isKindOfClass:[self class]])
    {
        return YES; //if there are two nested custom scrollviews  
    }

    if ([view isKindOfClass:[UIButton class]] || [view isKindOfClass:[CustomSegmentedControl class]] || [[view superview] isKindOfClass:[CustomSegmentedControl class]]) {
        return YES;
    }

    if ([view isKindOfClass:[UIControl class]]) {
        return NO;
    }

    return YES;
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (!self.dragging) {
        for (UIView *sv in self.subviews) {
            if ([sv isKindOfClass:[CustomSegmentedControl class]])
            {   //if there is more than one add a tag or tomething
                [(CustomSegmentedControl *)sv setTouchProcessed:YES];
                [sv touchesBegan:touches withEvent:event];
                return;
             }
        }
    }
}

完美运作！
