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{

[UIViewbeginAnimations:nilcontext:NULL];

[UIViewsetAnimationDuration:0.3];

[UIViewsetAnimationDelegate:self];

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

[UIViewcommitAnimations];

[textField resignFirstResponder];

return YES;

}

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

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField

{

[UIViewbeginAnimations:nilcontext:NULL];

[UIViewsetAnimationDuration:0.3];

[UIViewsetAnimationDelegate:self];

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

[UIViewcommitAnimations];

return YES;

}
