iPhone: TableView inside UIScrollview，显示接种疫苗滚动条

Question

我已经在滚动视图中添加了一些表格和其他vies。在表格中滚动工作正常。但在父滚动视图中，当滚动时，会显示一个摇摆的垂直滚动条，有时甚至会出现在屏幕的中间。有时会在屏幕左侧显示。并且不限于垂直滚动条区域。当我设置showsVerticalScrollIndicator = NO时，它没有显示。但是你知道为什么滚动条要到处移动吗？

DashboardView是UIScrollView的一个子类。

dashboard=[[DashboardView alloc] initWithFrame:fullScreenRect];
dashboard.contentSize = CGSizeMake(320,700); // must do!
dashboard.showsVerticalScrollIndicator = YES;
dashboard.bounces = YES;
self.view = dashboard;


@implementation DashboardView

- (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        // Initialization code
    }
    return self;
}

- (void)drawRect:(CGRect)rect {
    // Drawing code
}

- (void) layoutSubviews{

    NSArray *views = self.subviews; 

    [UIView beginAnimations:@"CollapseExpand" context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

    UIView *view = [views objectAtIndex: 0];
    CGRect rect = view.frame;

    for (int i = 1;  i < [views count]; i++ ) {     
        view = [views objectAtIndex:i];
        view.frame = CGRectMake(rect.origin.x, rect.origin.y + rect.size.height, view.frame.size.width, view.frame.size.height);
        rect = view.frame;
    }

    [UIView commitAnimations];

}

Answer 1

记住，scrollbars也是scroll的子视图。在对视图执行某些操作之前，将其从views数组中排除。

Answer 2

是啊。这解决了我的问题。看起来Scrollbar是一种UIImageView。如果有人需要它，这是我的新代码，它工作得很好。

(void) layoutSubviews{

NSArray *views = self.subviews; 

[UIView beginAnimations:@"CollapseExpand" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

//CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];       
//  [self.view insertSubview:balanceView belowSubview:profileView];


UIView *view = [views objectAtIndex: 0];
CGRect rect = view.frame;

for (int i = 1;  i < [views count]; i++ ) {     
    view = [views objectAtIndex:i];
    if ([view isMemberOfClass: [UIView class] ]) {
        //CFShow(view);
        view.frame = CGRectMake(rect.origin.x, rect.origin.y + rect.size.height, view.frame.size.width, view.frame.size.height);
        rect = view.frame;          
    }

}

[UIView commitAnimations];

}
