【解决方案1】：

工作代码....

1) 设置delegate给你textFields

[self.textField setDelegate:self];

2) 向上移动textField

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    if (textField == self.textField)
    {
        [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 - 80), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];
    }
}

3) 向下移动textField

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    if (textField == self.textField)
    {
        [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 + 80), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];
    }
}

4) 向上移动textView

-(void)textViewDidBeginEditing:(UITextView *)textView
{
    if (textView == self.textView)
    {
        [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 - 80), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];
    }
}

5) 将textView 向下移动

-(void)textViewDidEndEditing:(UITextView *)textView
{
    if (textView == self.textView)
    {
        [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 + 80), self.view.frame.size.width, self.view.frame.size.height);
        [UIView commitAnimations];
    }
}
