在uiview中动态添加标签，然后将uiview添加到scrollview ios

我正在尝试制作一个应用程序，其中我在界面生成器中添加一个scrollview，然后在.m文件中，我在UIView中动态添加两个标签，然后在scrollview中动态添加此UIView。这是在for循环中完成的

我用于scrollview的代码：

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

self.scrollView.contentSize = CGSizeMake(0, self.scrollView.frame.size.height + kbSize.height);
}

// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
self.scrollView.contentSize = CGSizeMake(0, self.scrollView.frame.size.height);
}

添加两个标签的代码为：

UILabel  * label1 = [[UILabel alloc] initWithFrame:CGRectMake(10, 0 + Y,label1.frame.size.width, 21)];
label1.text = @"label1";
#and all label1 propertiies

UILabel  * label2 = [[UILabel alloc] initWithFrame:CGRectMake(10, 21 + Y, label2.frame.size.width, 21)];
label2.text = @"label2";

UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, view1.frame.size.width, 42)];

CGRect frame;
frame = view1.frame;
[self.scrollView setContentSize:(CGSize){ self.scrollView.contentSize.width,frame.size.height + kbSize.height}];
[self.scrollView addSubview:view1];
                [view1 addSubview:label1];
                [view1 addSubview:label2];

标签已生成，但问题是我无法向下滚动它们

我不知道是什么问题。我是新来的

这条路对吗？还有别的路吗

希望问题清楚

这是代码，它可以工作，但我不确定这是否是您正在搜索的内容

对于（NSInteger i=1；i很可能您的contentSize小于ScrollView框架，或者它们相等。您必须将contentSize设置得更大。此外，不建议设置contentSize，最好使用contentInset，在这里您可以找到有关contentInset的更多信息。您可以编辑上述代码吗？@GeorgeK您检查了
frame.si的结果值吗ze.height+kbSize.height
请准确解释您想要什么，我将尝试复制，或者尝试给您一些advice@BogdanSomlea我有一个for循环，其中生成了一个uiview，在uiview中生成了两个标签，这个uiview在一个scrollview中每个uiview必须有2个标签。代码工作正常，但当显示键盘时，一些文本位于键盘下方。如何解决该问题？无法解决它…而且我有一个疑问，我想向每个视图添加点击功能，使用上面的代码我能做到吗？是的，你能做到，文本字段放在哪里？t代码对tap非常有效，但我遇到了标签的定位问题（生成的uiview工作不正常，请尝试触摸所有标签），当我搜索时，我发现我应该关闭自动布局，所以尝试了它，但不起作用，我知道我在寻求帮助，请查看我的编辑，请告诉我它是否起作用，我还添加了一个随机颜色的方法，这样我可以看到视图是否正确绘制，您可以删除它，但我认为它将帮助您
