textField或textviewz处理键盘弹出时遮住输入框的比较简捷得方法

- (void)textFieldDidBeginEditing:(UITextField *)textField  

{  

    float offset = 0.0f;  

    if(self.txt_name == textField)  

    {  

        offset = - 180.0f;  

    }  

    NSTimeInterval animationDuration = 0.30f;  

    [UIViewbeginAnimations:@"ResizeForKeyBoard"context:nil];  

    [UIViewsetAnimationDuration:animationDuration];  

    float width = self.view.frame.size.width;  

    float height = self.view.frame.size.height;  

    CGRect rect = CGRectMake(0.0f, offset , width, height);  

    self.view.frame = rect;  

    [UIViewcommitAnimations];  

}  

- (void)textFieldDidEndEditing:(UITextField *)textField

{

    float offset = 0.0f;  

   

    NSTimeInterval animationDuration = 0.30f;  

    [UIViewbeginAnimations:@"ResizeForKeyBoard"context:nil];  

    [UIViewsetAnimationDuration:animationDuration];  

    float width = self.view.frame.size.width;  

    float height = self.view.frame.size.height;  

    CGRect rect = CGRectMake(0.0f, offset , width, height);  

    self.view.frame = rect;  

    [UIViewcommitAnimations];  

}

以上是textfeild得处理方法。textview用textViewDidBeginEditing和textViewDidEndEditing。
