Answer 1

可能低于答案对你有帮助。关注此

//just give your URL instead of my URL
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL  URLWithString:@"Your URL"]];

[request setHTTPMethod:@"GET"];

[request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"content-type"];

NSError *err;

NSURLResponse *response;

NSData *responseData = [NSURLConnection sendSynchronousRequest:request   returningResponse:&response error:&err];

//You need to check response.Once you get the response copy that and paste in ONLINE JSON VIEWER.If you do this clearly you can get the correct results.    

//After that it depends upon the json format whether it is DICTIONARY or ARRAY 

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

从上面的代码中，您可以获得正确的JSON格式。试试这个。

Answer 2

NSMutableCharacterSet *charactersToRemove = [NSMutableCharacterSet new]; [charactersToRemove addCharactersInString:@"\n"]; [charactersToRemove addCharactersInString:@"\\"]; //This respresent obly one backslash, In Objective-c you have to support it with another slash [jsonString stringByTrimmingCharactersInSet:charactersToRemove];
