我想解析以下與我的JSON解析器。我嘗試了幾種方法，但實際的JSON序列化NSJSONSerialization總是拋出錯誤（實際上它拋出NSArray * termArray = [dataDictionary objectForKey：@「term」];但原因是，因爲dataDictionary沒有正確的響應所以我徘徊，爲什麼，因爲URL請求似乎工作JSON解析結果發送無法識別的選擇器
'NSInvalidArgumentException' 的，原因是：「 - [__ NSCFArray objectForKey：]：無法識別的選擇發送到實例

這是我使用解析
NSURL *myURL = [NSURL URLWithString:@"https://api.quizlet.com/2.0/users/<myUser>/sets?access_token=<myAccessToken>&whitespace=1"];
NSData *jsonData = [NSData dataWithContentsOfURL:myURL];
NSError *error = nil;
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
NSArray *termArray = [dataDictionary objectForKey:@"term"];
