stirng 讀取json檔案 jsonkit 使用

1.將字典或者數組還原序列化為NSString.    NSMutableDictionary *jsonDic = [NSMutableDictionary dictionary];    NSMutableDictionary *alert = [NSMutableDictionary dictionary];    NSMutableDictionary *aps = [NSMutableDictionary dictionary];    [alert setObject:@"a msg come!" forKey:@"body"];    [aps setObject:alert forKey:@"alert"];    [aps setObject:@"3" forKey:@"bage" ];    [aps setObject:@"def.mp3" forKey:@"sound"];    [jsonDic setObject:aps forKey:@"aps"];        NSString *strJson = [jsonDic JSONString];        NSLog(@"%@",strJson);        //    2.將NSString還原序列化為數組、字典.    NSDictionary *result = [strJson  objectFromJSONString];//    或者    NSDictionary *result = [dataJson  objectFromJSONData];        NSLog(@"%@",result);
NSError *error;NSString *textFileContents = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"json" ofType:@"txt"] encoding:NSUTF8StringEncoding error:&error];if (textFileContents == nil) {NSLog(@"Error reading text file. %@", [error
 localizedFailureReason]);}NSDictionary *result = [textFileContents objectFromJSONString];NSLog(@"res= %@", [result objectForKey:@"cmd"]);
