IOS开发中键盘输入屏幕上移的解决方法

//遵循协议@interface ViewController ()<UITextFieldDelegate>//设置属性@property(nonatomic,strong)UITextField* UITF;//设置代理UITF.delegate=self;//代理方法//键盘弹出时屏幕上移-( void )textFieldDidBeginEditing:(UITextField *)textField{　 //假如多个输入，比如注册和登录，就可以根据不同的输入框来上移不同的位置，从而更加人性化//键盘高度216//滑动效果（动画）NSTimeInterval animationDuration = 0.30f;[UIView beginAnimations:@ "ResizeForKeyboard" context:nil];[UIView setAnimationDuration:animationDuration];//将视图的Y坐标向上移动，以使下面腾出地方用于软键盘的显示self.view.frame = CGRectMake(0.0f, -100.0f/*屏幕上移的高度，可以自己定*/, self.view.frame.size.width, self.view.frame.size.height); [UIView commitAnimations];}//取消第一响应，也就是输入完毕，屏幕恢复原状-( void )textFieldDidEndEditing:(UITextField *)textField{//滑动效果NSTimeInterval animationDuration = 0.30f;[UIView beginAnimations:@ "ResizeForKeyboard" context:nil];[UIView setAnimationDuration:animationDuration];//恢复屏幕self.view.frame = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, self.view.frame.size.height); [UIView commitAnimations];}
