UITextView及UITextField处理键盘弹出视图上移

#pragma -mark UITextView Delegate
- (void)textViewDidEndEditing:(UITextView *)textView{
    //输入框编辑完成,视图恢复到原始状态
    self.view.frame = CGRectMake(0, 0, ScreenW, ScreenH);
}

-(void)textViewDidBeginEditing:(UITextView *)textView{

    CGRect frame = textView.frame;

    //在这里我多加了62，（加上了输入中文选择文字的view高度）这个依据自己需求而定
    int offset = (frame.origin.y+62)-(ScreenH-216.0);//键盘高度216

    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];

    [UIView setAnimationDuration:0.30f];//动画持续时间

    if (offset>0) {
        //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
        self.view.frame = CGRectMake(0.0f, -offset, ScreenW, ScreenH);
    }
    [UIView commitAnimations];
}

//UITextField 同理
#pragma -mark UITextField Delegate
-(void)textFieldDidBeginEditing:(UITextField *)textField{
}
