如何將提取的iCloud數據對象保存到單個數組中？

這是我所有的對象，我想將所有對象保存到單個數組中。如何將提取的iCloud數據對象保存到單個數組中？

我使用這個循環的人，讓所有的對象，並保存爲單個陣列：

for (int i = 0 ; i < dataArray.count; i++){ 
    for (int j = 0 ; j<[[dataArray objectAtIndex:i] count]; j++) { 
     total addObject:[dataArray objectAtIndex:j]]; 
    } 
}

你已經有'dataArray'中的數據對象了，你想達到什麼目的？ –

在對象2和3中也有3和2個對象，我嘗試循環獲取所有對象，並保存到單個數組中。但它不工作。 – iOS

使用C風格的迭代也不是絕對必要的，這裏是你能做什麼：

for(id object in dataArray) { 
    for(id subobject in object) { 
     [mutableArray addObject:subobject]; 
    } 
}

感謝穆罕默德的工作。 – iOS

沒問題，如果你想知道爲什麼你的代碼不工作，那是因爲'[total addObject：[dataArray objectAtIndex：j]];'應該是'[total addObject：[[dataArray objectAtIndex：i ] objectAtIndex：j]];' –
