禁用多點觸摸不工作ios

我有一個視圖控制器（VC）有3個按鈕（國家，州，市）。點擊這些按鈕後，我將展示另一個VC（使用popover segue），這是一個搜索表來搜索國家（或州或城市）。現在，如果用戶單擊兩個按鈕，則同時顯示兩個視圖控制器。我只想要一個人。如何做到這一點？禁用多點觸摸不工作ios

嘗試self.view.multipleTouchEnabled = NO;但不工作。代碼searchVC的：

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
    UIImage *bgApplication = [UIImage imageNamed:@"bg-app-568h.jpg"]; 
    self.view.backgroundColor = [UIColor colorWithPatternImage:bgApplication]; 

    self.searchItems = [self loadData]; 
    self.filteredSearchItems = [NSMutableArray arrayWithCapacity:[self.searchItems count]]; 

    for (UIView *view in self.SearchBarBase.subviews){ 
     if ([view isKindOfClass: [UITextField class]]) { 
      UITextField *tf = (UITextField *)view; 
      tf.delegate = self; 
      break; 
     } 
    } 
} 

- (NSArray *)loadData 
{ 
    MatchDayDataController * sharedController = [MatchDayDataController sharedDataController]; 
    NSArray *data = [sharedController fetchStates]; 
    //NSLog(@"states: %@", data); 

    return data; 
}

任何想法？

請分享一些可以幫助你的代碼。 :) – Rashad

self.view.multipleTouchEnabled = NO不應該工作，因爲每個按鈕是一個差異視圖。 –

觸摸後您的按鈕是否可用？或者用戶是否必須同時打兩個按鈕？爲什麼這是一個問題？有一件事你可以嘗試，就是讓一個方法處理所有三個按鈕，然後在運行時設置一個標誌。如果設置了該標誌，代碼將不會執行，因此如果該方法被調用兩次，代碼只運行一次。當你返回到vc時（例如，在結果視圖中調用的協議方法中），你重置標誌 – Moonwalkr

嘗試self.view.exclusiveTouch = YES;

不，這是一個壞主意。從文檔：「默認情況下，視圖的exclusiveTouch屬性設置爲NO。如果將該屬性設置爲YES，則標記該視圖，以便如果正在跟蹤觸摸，則它是窗口中唯一跟蹤觸摸的視圖在窗口中的其他意見不能接受這些接觸。「 – Moonwalkr

您可以創建這個變量的靜態布爾變量busy，並在每個按鈕的操作方法的第一線檢查狀態。如果busy等於NO，則將她設置爲YES，並在最後一行操作方法或其他位置將其設置爲NO。如果busy等於YES做動作返回的方法。所以，直到第一個被調用的方法沒有完成，沒有其他方法會運行。

@implementation yourController 

-(void)changeCountry 
{ 
    if (!busy) 
    { 
     busy = YES; 
     // do what you need 
    } else return; 
} 

-(void)changeState 
{ 
    if (!busy) 
    { 
     busy = YES; 
     // do what you need 
    } else return; 
} 

@end

您應該執行單，與布爾值返回一個靜態實例使用他差viewControllers（1 mainC + 3 popOverC），並設置busy到NO當你完成版。

同意你的看法，只不過第二個按鈕動作會在第一個動作完成時觸發（全部在同一個主線程中）。此外，我建議通過'[self performSelector：@selector（resetBusy）withObject：nil afterDelay：0];''用' - （void）resetBusy {busy = NO;} '（這會在主線程的下一個循環） –
