將數據添加到另一個NSDictionary中的NSDictionary

Question

我試圖將數據添加到嵌套在其他字典內的NSMutableDictionary。代碼之前，增加了數據

啓動輸出運行

DayData Dictionary {   //DayData Dictionary 

Monday =  {     //events Dictionary 
    trip1 =   {   //eventData Dictionary 
     numItems = 9items; 
     time = "5:00"; 
     tripName = beachfucking; 
    }; 
}; 
Thursday =  { 
    trip1 =   { 
     numItems = 9items; 
     time = "5:00"; 
     tripName = beachfucking; 
    }; 
}; 
Tuesday =  { 
    trip1 =   { 
     numItems = 9items; 
     time = "5:00"; 
     tripName = beachfucking; 
    }; 
}; 
Wendsday =  { 
    trip1 =   { 
     numItems = 9items; 
     time = "5:00"; 
     tripName = beachfucking; 
    }; 
}; 
} 

代碼生成此輸出

NSMutableDictionary *eventData = [[NSMutableDictionary alloc]initWithObjects:@[@"5:00",@"9items",@"beachfucking"] forKeys:@[@"time",@"numItems",@"tripName"]]; 

NSMutableDictionary *event = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
           eventData,@"trip1",nil]; 

NSMutableDictionary *dayData = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
             event,@"Monday",event,@"Tuesday", 
             event,@"Wendsday",event,@"Thursday",nil]; 

我現在嘗試解決問題。在這裏我創建一個新的事件NSDictionary然後將該數據添加到DayData Dictionary。但輸出不正確。星期一隻有假設時，每週的每一天都會獲得「trip2」數據集。從代碼

NSMutableDictionary *event2 = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
           eventData,@"trip2",nil]; 
[[dayData objectForKey:@"Monday"] addEntriesFromDictionary:event2]; 

電流輸出錯上述

2016-12-24 01:56:41.261329 test1[10098:380349] { 
    Monday =  { 
     trip1 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
     trip2 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
    }; 
    Thursday =  { 
     trip1 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
     trip2 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
    }; 
    Tuesday =  { 
     trip1 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
     trip2 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
    }; 
    Wendsday =  { 
     trip1 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
     trip2 =   { 
      numItems = 9items; 
      time = "5:00"; 
      tripName = beachfucking; 
     }; 
    }; 
    } 

通知TRIP2如何爲每週七天填寫。

您的所有日期鍵都包含相同的參考對象event，以便更改它之一，將反映到所有天鑰匙。

要解決該問題，請聲明您的dayDataDictionary這樣。

NSMutableDictionary *dayData = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
           [event mutableCopy] ,@"Monday",[event mutableCopy],@"Tuesday", 
           [event mutableCopy],@"Wendsday",[event mutableCopy],@"Thursday",nil];
