iPhone或iPhone 5在locationUpdate方法中的條件語句：方法

我在locationUpdate：方法中有此iPhone或iPhone 5條件語句。iPhone或iPhone 5在locationUpdate方法中的條件語句：方法

此代碼：

- (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iphone5的條件代碼時。它失敗。該應用程序不會崩潰，但只保留在視圖控制器（RootViewController）上，不會推送到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]; 


     } 
    } 

}

它似乎是其他如果聲明爲iPhone5這是問題。即使我將OffersViewControlleriPhone5更改爲OffersViewController，它也不起作用。

感謝您的任何幫助

你真的不應該這樣做，檢查屏幕大小，因爲任何事情都可以改變它，調用使狀態欄變大，旋轉將它們交換，等等...... – jjv360 2013-02-25 13:53:55

@ jjv360我發現此代碼來檢查適用於iPhone和iPhone5。測試使用哪種設備的更好方法是什麼？謝謝。 – hanumanDev 2013-02-25 13:55:01

嗯，這可能是根據屏幕尺寸顯示不同視圖的最佳方法，但通常視圖應該流動以便它們可以縮放以適合任何屏幕......這樣，您只有一個視圖可以管理和更新不同設備簡單... – jjv360 2013-02-25 13:57:14

只是想通了。我有一個}，在達到if(result.height == 1136) { 條件之前關閉了if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){ 。
