Question

**我无法解析以下JSON文件。它正在给the operation couldn’t be completed. (cocoa error 3840.)。

这是我的代码：

- (NSString *)loadJsFromFile:(NSString *)fileName
{
    NSString *path = [[NSBundle mainBundle]pathForResource:fileName ofType:@"txt"];
    NSString *jsScript = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
    return jsScript;
} 

//

 NSString *strInputParam = [self loadJsFromFile:@"samplein"];

 NSData *dataInput = [strInputParam dataUsingEncoding:NSUTF8StringEncoding];

 NSError *error;

 NSObject *input = [NSJSONSerialization JSONObjectWithData:dataInput options:NSJSONReadingMutableContainers error:&error];

 if(error)
 {
    NSLog(@"%@",error.localizedDescription);
 }

我也尝试了以下内容，但它没有帮助，请帮助我解析这个JSON。提前完成。

NSString *path = [[NSBundle mainBundle]pathForResource:@"samplein" ofType:@"txt"];
NSData *data = [[NSData alloc]initWithContentsOfFile:path];

NSError *error;

NSObject *input = [NSJSONSerialization JSONObjectWithData:dataInput options:NSJSONReadingMutableContainers error:&error];

if(error)
{
    NSLog(@"%@",error.localizedDescription);
}

这是我的JSON数据

这里有几个明显的问题：

<德尔> 1.你还没有发布这个方法的代码（```loadJsFromFile：```），所以我们可以评论一些错误。 ```NSString * strInputParam = [self loadJsFromFile：@＆＃34; samplein.txt＆＃34;];```

<德尔> 2.这些选择的意图是什么？ 0 | 1 | 2？ ```NSObject * input = [NSJSONSerialization JSONObjectWithData：dataInput options：0 | 1 | 2 error：＆amp; error];```

根据http://jsonlint.com/，您的JSON无效：

Parse error on line 1: sampleinputdata={ ^ Expecting '{', '['

因此，

sampleinputdata = { ... }无效JSON。也许你的意思是"sampleinputdata": { ... }，或者只是{ ... }。

注意：没有必要通过字符串传递数据，您可以直接从文件加载到NSData。所以你的第二种方法是你应该使用的方法。

无法解析obj c中的JSON文件
