SInvalidArgumentException'，原因：' - [__ NSArrayM objectForKey：]：

我不知道爲什麼索引處的對象失敗。我想知道這裏有沒有人知道如何解決這個問題。該失敗的具體代碼是NSURL *imgURLLogo = [NSURL URLWithString:[[firstMessage objectForKey:@"message"] objectForKey:@"photo"]];在無效加載圖像的底部任何人都可以請幫我弄清楚這一點？SInvalidArgumentException'，原因：' - [__ NSArrayM objectForKey：]：

您可能希望將其縮減爲可重現樣本，而不是現在的大量代碼。 –

做一個'NSLog（@「％@」，firstMessage）;'並顯示結果。這將決定答案。顯然，字典/數組的結構並不是你所期望的。 – Rob

好的，我做了你所要求的併發布了輸出。 – moo

貌似arrMessages是NSArray的陣列。所以arrMessages的第一個元素是NSArray而不是NSDictionary。

你知道我怎麼能解決這個問題嗎？ – moo

檢查objectsForContacts的填充位置。看起來問題不在這個代碼中。 – diederikh

NSMutableArray *arrMessages = [objectsForContacts objectForKey:[arrayOfUsers objectAtIndex:indexPath.row]];

什麼是objectsForContacts？它是一個數組還是字典？如果它是一個數組，那就是你出錯的地方。
