WatchOS - 讓int對所有wkinterfacecontroller都可見的最佳方法

Question

在wkinterfacecontroller 1中，我定義了兩個int值：base [8] [8]和player [8] [8]。使用for循環我爲兩者生成我的值。 現在我想geht訪問它們在wkinterfacecontroller 2和3.

但我真的不知道如何。將每個int保存在nsuserdefaults中並加載到其他控制器中有一點奇怪...

創建一個單例模型包含您的數據。從您需要此數據的所有視圖中引用此類。通過下面的代碼，您可以通過調用[Model sharedModel]來引用「模型」。訪問變量：[Model sharedModel].myVariableName。

// Model.m 
// This method will only create one instance of Model no matter how many times it's called. 
// Import its header and use this method to get its reference 
+ (instancetype)sharedModel 
{ 
    static Model *sharedModel; 

    static dispatch_once_t onceToken; 
    dispatch_once(&onceToken, ^{ 
     sharedModel = [[self alloc] initPrivate]; 
    }); 
    return sharedModel; 
} 

// Raise exception to make sure you don't create more than one object of the Model class 
- (instancetype)init { 
    [NSException raise:@"Singleton" 
       format:@"Use +[Model sharedModel]"]; 
    return nil; 
} 

// Private init method 
- (instancetype)initPrivate 
{ 
    if (self = [super init]) { 
     // Set properties 
    } 
    return self; 
}
