ios - UIScrollView - 滚动时内容超出范围

Question

我在 Interface Builder 中设计的 ScrollView 是这样的

这里看起来不错。但不幸的是，当我在模拟器或设备上运行它时

变成

scrollview 中的内容在 scrollview 本身之外扩展，即使在包含此 scrollView 的 UIView 之外也是如此。

在我的viewDidLoad中(panel是scrollView的容器)

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    CGFloat adjustPanelHeight = [PTTScreenScaleUtil getAdjustHeight:self.panel.frame.size.height];
    CGRect panelRect = self.panel.frame;
    panelRect.size.height = adjustPanelHeight;
    self.panel.frame = panelRect;

    UIImage *image = [UIImage imageNamed:@"panel-background"];
    UIGraphicsBeginImageContext(self.panel.frame.size);
    [image drawInRect:CGRectMake(0, 0, self.panel.frame.size.width, adjustPanelHeight)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    [self.panel setBackgroundColor:[UIColor colorWithPatternImage:newImage]];

    NSLog(@"scrollView Height : %f", self.scrollView.frame.size.height);
    NSLog(@"scrollView contentSize Height : %f", self.scrollView.contentSize.height);
//    CGRect scrollViewRect = self.scrollView.frame;
//    CGRect scrollViewContentRect = self.scrollView.frame;
//    NSLog(@"ScrollView Height Before : %f , After : %f", self.scrollView.frame.size.height, [PTTScreenScaleUtil getAdjustHeight:self.scrollView.frame.size.height]);
//    scrollViewRect.size.width = 280;
//    scrollViewRect.size.height = [PTTScreenScaleUtil getAdjustHeight:270];
//    self.scrollView.frame = scrollViewRect;
//    [self.detailsLabel sizeToFit];
    UIView *view = [[self.scrollView subviews] objectAtIndex:0];
//    [view sizeToFit];
//    [self.scrollView setContentMode:UIViewContentModeScaleAspectFit];
//    NSLog(@"ContentSize Height : %f", view.frame.size.height);
//    scrollViewContentRect.size.height = view.frame.size.height;
    NSLog(@"Bounds : %f", view.bounds.size.height);
    self.scrollView.frame = CGRectMake(10, 10, 280, 270);
    self.scrollView.contentSize = CGSizeMake(280, 500);
    NSLog(@"Frame Height %f", self.scrollView.frame.size.height);
    //[self.scrollView setContentSize: CGSizeMake(280, 1000)];

    CGRect termBtnRect = self.termBtn.frame;
    CGRect mailBtnRect = self.mailBtn.frame;
    CGRect twitterBtnRect = self.twitterBtn.frame;
    CGRect fbBtnRect = self.fbBtn.frame;
    termBtnRect.origin.y = adjustPanelHeight - 10 - termBtnRect.size.height;
    mailBtnRect.origin.y = adjustPanelHeight - 10 - termBtnRect.size.height;
    twitterBtnRect.origin.y = adjustPanelHeight - 10 - termBtnRect.size.height;
    fbBtnRect.origin.y = adjustPanelHeight - 10 - termBtnRect.size.height;
    self.termBtn.frame = termBtnRect;
    self.mailBtn.frame = mailBtnRect;
    self.twitterBtn.frame = twitterBtnRect;
    self.fbBtn.frame = fbBtnRect;
}

所有日志返回270.0

附言。滚动条是正确的，即使内容在外面但滚动条工作正常(留在 ScrollView 的框架中，在界面生成器中安排)我不知道如何解决这个问题。请任何人帮助我。

谢谢。

通过在界面生成器中创建新的 View Controller 来解决它，然后小心地重做相同的过程。它有效。

当我比较两个 View Controller 时，我意识到错误的 UIScrollView Clip Subviews 未被选中。当检查它时，问题就解决了。
