IOS中输入框被软键盘遮挡的解决办法

清华大佬耗费三个月吐血整理的几百G的资源,免费分享!....>>>

 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
