Question

我在locationUpdate：method中有这个iPhone或iPhone 5条件语句。

此代码有效：

- (void)locationUpdate:(CLLocation *)location {
    //locLabel.text = [location description];

#ifdef DEBUG    
    NSLog(@"auth status is %u", [CLLocationManager authorizationStatus]);
#endif


                UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
                OffersViewController *lvc = [storyboard instantiateViewControllerWithIdentifier:@"OffersViewController"];
                [self.navigationController pushViewController:lvc animated:NO];


}

但是当iphone5条件码时。它失败。该应用程序不会崩溃但只是保留在视图控制器（RootViewController）上，并且不会推送到OffersViewController或OffersViewControlleriPhone。

- (void)locationUpdate:(CLLocation *)location {
    //locLabel.text = [location description];

#ifdef DEBUG    
    NSLog(@"auth status is %u", [CLLocationManager authorizationStatus]);
#endif

    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if ([[UIScreen mainScreen] respondsToSelector: @selector(scale)]) {
            CGSize result = [[UIScreen mainScreen] bounds].size;
            CGFloat scale = [UIScreen mainScreen].scale;
            result = CGSizeMake(result.width * scale, result.height * scale);

            if(result.height == 960) {
                NSLog(@"iPhone 4 Resolution");

                UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
                OffersViewController *lvc = [storyboard instantiateViewControllerWithIdentifier:@"OffersViewController"];
                [self.navigationController pushViewController:lvc animated:NO];


            }
            **else if(result.height == 1136) {
                NSLog(@"iPhone 5 Resolution");

                UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
                OffersViewControlleriPhone5 *lvc = [storyboard instantiateViewControllerWithIdentifier:@"OffersViewControlleriPhone5"];
                [self.navigationController pushViewController:lvc animated:NO];

            }**
        }
        else {
            NSLog(@"Standard Resolution");

            UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
            OffersViewController *lvc = [storyboard instantiateViewControllerWithIdentifier:@"OffersViewController"];
            [self.navigationController pushViewController:lvc animated:NO];


        }
    }

}

似乎是iPhone5的else if语句就是问题所在。即使我将OffersViewControlleriPhone5更改为OffersViewController，它也不起作用。

感谢您的帮助

刚想通了。我有}在if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){条件到达之前关闭了if(result.height == 1136) {。
