Ios 聚焦输入文本框上的布局溢出

我一直在试图解决这个溢出问题，但似乎这不是因为我做得不对。是否有其他人遇到过此问题并能够解决

当我关注输入文本视图布局时，默认方向会向上滑动布局，但这与iPhone的顶部栏重叠。我该如何解决这个问题？我在下面附上了一个截图

非常感谢您的帮助

我的视图控制器：

#import "Contribute_VC.h"
#import "HomePage_VC.h"

#import "ChatViewCell.h"

@interface Contribute_VC ()

@end

[super viewDidLoad];

_AnswerView.layer.cornerRadius = 5;
_AnswerView.layer.borderColor = [UIColor whiteColor].CGColor;
_AnswerView.layer.masksToBounds = YES;

_btn_YES.layer.cornerRadius = 10;
_btn_YES.clipsToBounds = YES;

_btn_NO.layer.cornerRadius = 10;
_btn_NO.clipsToBounds = YES;
}

这不是通常的行为，而是应该“呆在原地”。您在视图控制器中添加了什么代码？@AlejandroIván我已经更新了问题中的代码。请检查。这是故事板标记XML。我说的是你添加的Objective-C和/或Swift代码？我没有看到任何与键盘相关的代码，可能是你在库中做的或类似的事情。如果您想滚动内容，而不是简单地更改内容视图的框架或边界，那么最好使用

UIScrollView

并简单地更改其

contentInset

。与这个答案大致相同：您要问的问题位于此处：，但是，对于这个问题仍然没有真正“好”的解决方案
