- (void) animateTextField: (UITextField*) textField up: (BOOL) up 
{ 
    const int movementDistance = 150; // tweak as needed 
    const float movementDuration = 0.3f; // tweak as needed 

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

    [UIView beginAnimations: @"anim" context: nil]; 
    [UIView setAnimationBeginsFromCurrentState: YES]; 
    [UIView setAnimationDuration: movementDuration]; 
    self.view.frame = CGRectOffset(self.view.frame, 0, movement); 
    [UIView commitAnimations]; 
} 

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView{ 

     [self animateTextField: textField up: YES]; 
} 
- (void)textViewDidEndEditing:(UITextView *)textView{ 
      [self animateTextField: textField up: NO]; 

}

你应该将你的观点了，使键盘犯规覆盖文本框/ TextView的。这样的事情...

- (void)textFieldDidBeginEditing:(UITextField *)textField 
{ 
    if (textField == *textFieldName*) 
    { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     self.view.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.origin.y - 65.0), self.view.frame.size.width, self.view.frame.size.height); 
     [UIView commitAnimations]; 

    } 
} 

- (void)textFieldDidEndEditing:(UITextField *)textField 
{ 
    if (textField == *textFieldName*) 
    { 
     [UIView beginAnimations:nil context:NULL]; 
     [UIView setAnimationDelegate:self]; 
     [UIView setAnimationDuration:0.5]; 
     [UIView setAnimationBeginsFromCurrentState:YES]; 
     self.view.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.origin.y + 65.0), self.view.frame.size.width, self.view.frame.size.height); 
     [UIView commitAnimations]; 
    } 
} 

和TextView的使用：

- (void)textViewDidBeginEditing:(UITextView *)textView 

和

- (void)textViewDidEndEditing:(UITextView *)textView

你可以改变你的整个视图向上或只是移动控件（文本字段，文本视图）向上..或使您的视图可滚动，以便用户可以向下滚动，而键盘可见。
