如何字符串轉換爲NSArray的iOS中

我有一個JSON對象，它有一個鍵值對這樣如何字符串轉換爲NSArray的iOS中

"AttachedDocument": "[{\"DocumentId\":354,\"DocumentName\":\"Screenshot_2016-04-15-00-35-11.png\",\"DocumentType\":\"image/png\"}]"

這個值來作爲字符串。我怎麼可以轉換成NSArray

完整的對象

    "BaseType": "ess", 
    "StartDate": "2016-10-24T00:00:00", 
    "EndDate": "2016-10-24T00:00:00", 
    "NoOfDays": 1, 
    "StartDateSession": "full",

    "DeletedBy": 0, 
    "DeletedDate": "0001-01-01T00:00:00", 
    "ModuleId": 2, 
    "ObjectId": 20, 
    "StartDateString": "10/24/2016", 
    "EndDateString": "10/24/2016", 
    "LeaveDayList": [

    ], 
    "SystemLeaveTypeCode": "ANN", 
    "LeaveTypeName": "ANNUAL", 
    "Employee": null, 
    "LieuDayList": null, 
    "BaseLeaveType": "ANN",

你在哪裏/如何接收？它來自URLRequest嗎？你如何獲得這種格式的字符串？ – Fogmeister

這是JSON內的JSON字符串表示。可能的重複[在Objective-C中解析JSON內JSON]（http://stackoverflow.com/questions/33149110/parsing-json-within-json-in-objective-c） – Larme

其實你正在josn string作爲迴應，這樣你就可以將其轉換爲josn object類似，

NSString *yourString = @"[{\"DocumentId\":354,\"DocumentName\":\"Screenshot_2016-04-15-00-35-11.png\",\"DocumentType\":\"image/png\"}]"; 

NSError *error; 
NSData *data = [yourString dataUsingEncoding:NSUTF8StringEncoding]; 
NSArray *jsonObject = [NSJSONSerialization JSONObjectWithData:data 
            options:NSJSONReadingMutableContainers 
            error:&error]; 

    NSLog(@"json object : %@",jsonObject);

這裏yourString意味着對象AttachedDocument關鍵！
