推荐答案

你必须设置，

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return YES;
}

以便您可以获得所有类型的方向。最好根据方向重新定位控件。所以在屏幕上找到位置并将其设置为如下所示，

so that you can get all type of orientations. It's better to use reposition your controls according to the orientation. so find the location on screen and set it as given below,

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration {

    if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation ==   UIInterfaceOrientationPortraitUpsideDown) { 
        NSLog(@"login portrait");


        okButton.frame = CGRectMake(69, 286, 72, 28);
        cancleButton.frame = CGRectMake(178, 286, 72, 28);
        usernameLabel.frame = CGRectMake(92, 140, 149, 16);
        passwordLabel.frame = CGRectMake(129, 208, 75, 16);
        usernameField.frame = CGRectMake(69, 164, 181, 31);
        passwordField.frame = CGRectMake(69, 237, 181, 31);
        mainLabel1.frame = CGRectMake(35, 58, 250, 21);
        mainLabel2.frame = CGRectMake(35, 77, 153, 21);
        [backgroundImage setImage:[UIImage imageNamed:@"portraitLogin.jpg"]];
    } else {
        NSLog(@"login landscape");


        signinButton.frame = CGRectMake(190, 183, 86, 27);
        cancleButton.frame = CGRectMake(309, 183, 86, 27);
        usernameLabel.frame = CGRectMake(50, 100, 120, 21);
        passwordLabel.frame = CGRectMake(50, 139, 75, 21);
        usernameField.frame = CGRectMake(190, 95, 205, 31);
        passwordField.frame = CGRectMake(190, 134, 205, 31);
        mainLabel1.frame = CGRectMake(50, 58, 245, 19);
        mainLabel2.frame = CGRectMake(295, 58, 153, 19);
        [backgroundImage setImage:[UIImage imageNamed:@"landscapeLogin.jpg"]];
    }

}

找到适合控制的地方，并在CGRectMake函数中指定。

Find right places for control and specify that in CGRectMake function.

也是所有控件，

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
    self.usernameLabel = nil;
    self.usernameField = nil;
    self.passwordLabel = nil;
    self.passwordField = nil;
    self.okButton = nil;
    self.cancleButton = nil;
    self.backgroundImage = nil;
    self.mainLabel1 = nil;
    self.mainLabel2 = nil;
}

希望它适合你。
