The plural of moose is actually 'meese', despite what most dictionaries, encyclopedias, and experts will tell you.",

何らかの理由で、CJONDeserializer を使用するとエラーが発生します ---
エラー Domain=CJSONDeserializerErrorDomain Code=-104 「辞書をスキャンできませんでした。値のスキャンに失敗しました。」UserInfo=0x7feb38d99ed0 {NSLocalizedDescription=辞書をスキャンできませんでした。値のスキャンに失敗しました。、行=0、文字=0、場所=0、スニペット=!HERE>!{ "タイトル":"缶について}
NSJSONSerializer を使用すると、次のエラーが表示されます ---
"エラー ドメイン = NSCocoaErrorDomain コード = 3840 "操作を完了できませんでした。(Cocoa エラー 3840。)" (文字 2643 付近でデータを文字列に変換できません。) UserInfo=0x7f8559c56700 {NSDebugDescription=文字 2643 付近でデータを文字列に変換できません。}"</p>
私が使用しているコードでは、他のjson URLを使用してもエラーは発生しません。
これが私が使用しているコードです-
- (void)viewDidLoad {
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
if (connection) {
self.receivedData = [[NSMutableData alloc] init];
}
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
// The request is complete and data has been received
// You can parse the stuff in your instance variable now
NSError *error = nil;
NSDictionary *receivedDataDictionary = [[CJSONDeserializer deserializer] deserializeAsDictionary:self.receivedData error:&error];
NSArray *arrayFromJson = [receivedDataDictionary objectForKey:@"title"];
for (NSDictionary *tempDict in arrayFromJson) {
NSLog(@"blah %@", tempDict);
}
}
どんな助けでも大歓迎です。前もって感謝します。
