UIScrollView中的UITextField键盘遮挡问题的最简单解决办法

两步:

1重载textFieldDidBeginEditing

- (void)textFieldDidBeginEditing:(UITextField *)textField

{

    foucsTextField = textField;

    s_mainScrollView.contentSize = CGSizeMake(__SCREEN_WIDTH,__SCREEN_HEIGHT +216);//原始滑动距离增加键盘高度

    CGPoint pt = [textField convertPoint:CGPointMake(0, 0) toView:s_mainScrollView];//把当前的textField的坐标映射到scrollview上

    if(s_mainScrollView.contentOffset.y-pt.y+NAVIGATION_BAR_HEIGHT<=0)//判断最上面不要去滚动

        [s_mainScrollView setContentOffset:CGPointMake(0, pt.y-NAVIGATION_BAR_HEIGHT) animated:YES];//华东

}

2:重载textFieldShouldReturn

- (BOOL)textFieldShouldReturn:(UITextField*)theTextField

{

    {

        [theTextField resignFirstResponder];

        

        //开始动画 

        [UIView beginAnimations:nil context:nil];  

        //设定动画持续时间 

        [UIView setAnimationDuration:0.3];

        s_mainScrollView.frame = CGRectMake(0, NAVIGATION_BAR_HEIGHT, __SCREEN_WIDTH, __SCREEN_HEIGHT);

        s_mainScrollView.contentSize = CGSizeMake(__SCREEN_WIDTH,__SCREEN_HEIGHT);

        //动画结束 

        [UIView commitAnimations]; 

        

       

    }

    return YES;

}

这样就可以自动的滑动scrollview里面的输入控件了.
