Question

我有问题我在表格视图中有15个文本字段。当我输入文本到最后一个文本字段时，它是由键盘覆盖。任何人请给我一个解决方案。

我的文本字段位于IPAD分割视图的详细视图中，

提前感谢您的解决方案

Answer 1

您可以添加以下编码行：

//method to move the view up/down whenever the keyboard is shown/dismissed
-(void)setViewMovedUp:(BOOL)movedUp
{

   [UIView beginAnimations:nil context:NULL];
   [UIView setAnimationDuration:0.3]; // if you want to slide up the view

CGRect rect = self.view.frame;
if (movedUp)
{
    NSLog(@"MOVE-UP");
    // 1. move the view's origin up so that the text field that will be hidden come above the keyboard
    // 2. increase the size of the view so that the area behind the keyboard is covered up.
    rect.origin.y -= kOFFSET_FOR_KEYBOARD;
    // rect.size.height += kOFFSET_FOR_KEYBOARD;
}
else
{
    NSLog(@"MOVE-DOWN");
    // revert back to the normal state.
    rect.origin.y += kOFFSET_FOR_KEYBOARD;
    // rect.size.height -= kOFFSET_FOR_KEYBOARD;
}
self.view.frame = rect;

[UIView commitAnimations];
}

-(void)keyboardWillShow
{
   // Animate the current view out of the way
   if (self.view.frame.origin.y >= 0)
   {
       [self setViewMovedUp:YES];
   }
   else if (self.view.frame.origin.y < 0)
   {
      [self setViewMovedUp:NO];
   }
 }


 -(void)keyboardWillHide
 {
    if (self.view.frame.origin.y >= 0)
    {
       [self setViewMovedUp:YES];
    }
    else if (self.view.frame.origin.y < 0)
    {
       [self setViewMovedUp:NO];
    }
 }

在viewDidAppear中：

 -(void)viewDidAppear:(BOOL)animated
 {

     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];
     [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide) name:UIKeyboardWillHideNotification object:nil];

 }

你必须定义这个#define kOFFSET_FOR_KEYBOARD 100.0 //你想要的

Answer 2

//文本字段编辑开始时调用

- （void）textFieldDidBeginEditing：（UITextField *）textField {

        [self animateTextField: indexPath up: YES];

}

//编辑结束后的文字字段

（void）textFieldDidEndEditing：（UITextField *）textField {
```
[self animateTextField: indexPath up: NO];
```

}

// animateTextField的代码。移动距离将根据需要改变

（void）animateTextField：（NSIndexPath *）indexPath up：（BOOL）up {

const int movementDistance = indexPath.section == 0？20：180;

const float movementDuration = 0.3f;

int movement =（up？-movementDistance：movementDistance）;

的NSLog（@ “运动：％d”，移动）;

[UIView beginAnimations：@“aimation”context：nil];

[UIView setAnimationBeginsFromCurrentState：YES];

[UIView setAnimationDuration：movementDuration];

self.view.frame = CGRectOffset（self.view.frame，0，move）;

[UIView commitAnimations];

}

iPad键盘在表格视图中包含UITextField
