uitextfield键盘遮挡问题

键盘遮挡无非是要上移view,然后还原.

//键盘出现时,view上移
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationDelegate:self];
self.view.frame = CGRectMake(0, -130, 320, 460); //130就是上移的距离
[UIView commitAnimations];

//键盘消失后,view还原
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationDelegate:self];
self.view.frame = CGRectMake(0, 0, 320, 460); //还原
[UIView commitAnimations];

下面附上我的项目中当用uitextfield时处理键盘遮挡问题：

//chenyong textfield委托方法，当按下Return时键盘收起

-(BOOL)textFieldShouldReturn:(UITextField *)textField{

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3];

    [UIView setAnimationDelegate:self];

    self.view.frame = CGRectMake(0, 0, 320, 460);//还原

    [UIView commitAnimations];

    

    [textField resignFirstResponder];

    return YES;

}

//-(BOOL)textFieldShouldEndEditing:(UITextField *)textField

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField

{

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.3];

    [UIView setAnimationDelegate:self];

    self.view.frame = CGRectMake(0, -130, 320, 460);//130就是上移的距离

    [UIView commitAnimations];

    

    return YES;

}
