IOS中输入框被软键盘遮挡的解决办法详解手机开发

 实现方法：

   1）将输入框的代理设置为self

       （在lb文件中将输入框的delegate设置为File’s Owner 。或者使用代码textField.delegate = self;

   2）将输入框所对应的ViewController.h设置实现了UITextFieldDelegate协议

         在ViewController.m文件中实现UITextFieldDelegate的三个方法即可：

 
    //开始编辑输入框的时候，软键盘出现，执行此事件   
    -(void)textFieldDidBeginEditing:(UITextField *)textField   
    {   
        CGRect frame = textField.frame;   
        int offset = frame.origin.y + 32 - (self.view.frame.size.height - 216.0);//键盘高度216   
           
        NSTimeInterval animationDuration = 0.30f;   
        [UIView beginAnimations:@"ResizeForKeyboard" context:nil];   
        [UIView setAnimationDuration:animationDuration];   
           
        //将视图的Y坐标向上移动offset个单位，以使下面腾出地方用于软键盘的显示   
        if(offset > 0)   
            self.view.frame = CGRectMake(0.0f, -offset, self.view.frame.size.width, self.view.frame.size.height);   
           
        [UIView commitAnimations];   
    }   
       
    //当用户按下return键或者按回车键，keyboard消失   
    -(BOOL)textFieldShouldReturn:(UITextField *)textField   
    {   
        [textField resignFirstResponder];   
        return YES;   
    }   
       
    //输入框编辑完成以后，将视图恢复到原始状态   
    -(void)textFieldDidEndEditing:(UITextField *)textField   
    {   
        self.view.frame =CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);   
    }  

方法很简单吧？请注意一定不要忘记设置输入框的代理delegate哦
