呼叫多個視圖控制器的UITableView

Question

我使用這兩種協議是這樣的：

@protocol ModalClosedProtocol <NSObject> 

-(void) modalClosedGlobalProtocolMethod; 

@end 

和syncmlClient協議。

有三類ContactsViewController，EventViewController，ImageSettingViewController。這些類使用ModalclosedProtocol和syncmlClient protocol.all這三類預計從SettingViewController類來實現ModalClosedProtocol和syncmlClient protocol.It是當前實現的只是一個簡短的概述。
在我SettingViewController我正在處理表委託方法didSelectRow。對於代碼保理我創建了從0​​稱爲一個獨立的方法..像這樣：

-(void) checkDeviceAndHandleModelSizeForFlip:(FlipsideViewController *)flipVc orContact:(ContactsViewController *)contactVc orEvent:(EventViewController *)eventVc orImage:(ImageSettingViewController *)imageSettingVc 
{ 
    UIViewController *genericVC; 
    if (flipVc!=nil) 
    { 
     genericVC = flipVc; 
     flipVc.modalClosedProtocolDelegate = self; 
     flipVc.syncmlClient = self.syncmlClient; 

    } 
    else if (contactVc!=nil) 
    { 
     genericVC = contactVc; 
     contactVc.modalClosedProtocolDelegate = self; 
     contactVc.syncmlClient = self.syncmlClient; 
     contactVc.mainViewController = self.mainViewController; 
    } 
    else if (eventVc!=nil) 
    { 
     genericVC = eventVc; 
     eventVc.modalClosedProtocolDelegate = self; 
     eventVc.syncmlClient = self.syncmlClient; 
     eventVc.mainViewController = self.mainViewController; 
    } 
    else if (imageSettingVc!=nil) 
    { 
     genericVC = imageSettingVc; 
     imageSettingVc.modalClosedProtocolDelegate = self; 
     imageSettingVc.syncmlClient = self.syncmlClient; 
     imageSettingVc.mainViewController = self.mainViewController; 

    } 

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) 
    { 
     genericVC.modalPresentationStyle = UIModalPresentationFormSheet; 
     [self presentViewController:genericVC animated:YES completion:nil]; 
     genericVC.view.superview.frame = CGRectInset(genericVC.view.superview.frame, 100, 50); 
    } 
    else 
    { 
     genericVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; 
     [self presentViewController:genericVC animated:YES completion:nil]; //alok 

    } 
} 

基本上，如果你看到有很多redudancy的代碼在if/else子句中。如果我有一個單一的UIViewController對象，從代碼管理的角度來看會更好。

genericVC = contactVc;//vc object passed from didSelectrow it may be contact/event/image 
    genericVC.modalClosedProtocolDelegate = self; 
    genericVC.syncmlClient = self.syncmlClient; 
    genericVC.mainViewController = self.mainViewController; 

有人可以幫我解決這個問題。
感謝

Answer 1

只需申報您的genericVC這樣的：

UIViewController<ModalClosedProtocol, syncmlClient> *genericVC; 

這樣，你讓編譯器知道你genericVC視圖控制器符合協議ModalClosedProtocol和syncmlClient，所以要方法電話在那裏。

Answer 2

[self checkDeviceAndHandleModelSizeForFlip:self.flipVc];//Pass contactVc, eventVc, imageSettingVc like that, 

-(void) checkDeviceAndHandleModelSizeForFlip:(ViewController *)viewController 
{ 
    UIViewController *genericVC; 
    if (viewController!=nil) 
    { 
     genericVC = viewController; 
     viewController.modalClosedProtocolDelegate = self; 
     viewController.syncmlClient = self.syncmlClient; 
     viewController.mainViewController = self.mainViewController; 

    } 
}
