我觉得我在这里遗漏了一些非常明显的东西。

我在情节提要中有一个 UIScrollView，有一个到视图控制器的出口。

我以编程方式添加一系列视图，并设置滚动视图的内容大小。

即使我已将滚动视图的 contentsize 高度设置为非常高的值，我也无法滚动超出视图范围。

设置后我正在打印内容大小和帧大小。以及滚动视图滚动时的 contentoffset.y 。

这是控制台输出的示例：

如您所见，我无法滚动超过 200 多个。

我对 iOS 并不陌生，之前也使用过滚动视图，所以我觉得我一定错过了一些非常明显的东西。

非常感谢任何帮助，截止日期很紧！

编辑：添加代码：

checkboxes = [[NSMutableArray alloc] init];
{
    // Just indented scope for tidyness, no functional meaning
    [checkboxes addObject:[self createCheckboxWithLabel:@"Oil Level Checked"
                                                     atY:190]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Coolant Level Checked"
                                                         atY:240]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Tyre pressures & tread dept checked"
                                                         atY:290]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Warning beacon & horn operating"
                                                         atY:340]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Lights & indicators working & clean"
                                                         atY:390]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Screen was & wipers operational"
                                                         atY:440]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Mirrors undamaged & clean"
                                                         atY:490]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Road Tax & MOD discs present & valid"
                                                         atY:540]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"PPE in vechile"
                                                         atY:590]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Fire Extinguisher & First Aid kit present"
                                                         atY:640]];
    [checkboxes addObject:[self createCheckboxWithLabel:@"Wheel nuts checked with torque wrench"
                                                         atY:690]];
}
for(WpCheckboxWithLabelView *checkbox in checkboxes){
    [scrollView addSubview: checkbox];
}

// Set content size of scrollview
scrollView.contentSize = CGSizeMake(0, 10000);
scrollView.delegate = self;
NSLog(@"scrollView frame size: %f,%f", scrollView.frame.size.width, scrollView.frame.size.height);
NSLog(@"scrollView content size: %f,%f", scrollView.contentSize.width, scrollView.contentSize.height);

自动布局是这里问题的原因。我不太确定细节，但Apple 的文档描述了 s 与自动布局配对时的行为差异UIScrollView。

我相信我的问题是由于在故事板中定义的滚动视图和以编程方式添加的子视图。为了解决这个问题，我也以UIScrollView编程方式创建了这个问题。

我的观点和我的观点相同，它对我来说很好。我附上了代码：

CGSize s = CGSizeMake(mainDetailView.frame.size.width,
                      view1.frame.size.height + MARGIN +
                      view2.frame.size.height + MARGIN +
                      view3.frame.size.height + MARGIN +
                      view4.frame.size.height + MARGIN + 10000);

[mainDetailView setContentSize:s];

mainDetailView.clipsToBounds = NO;
mainDetailView.pagingEnabled = NO;

Margin 是一个常数，我定义为 20。

我可以滚动超出视图的限制。

也许您可以发布您的代码，这样会更容易为您提供帮助。
