[英]I send some data to a webservice, it returns some JSON as NSData. How to convert to Dict?(iOS 4.3)
I send some credentials to a web-service. 我将一些凭据发送到Web服务。
I can get the responce as NSData or as an NSString. 我可以将响应作为NSData或NSString来获取。
Whats the simpleist way to convert the (NSData or NSString)JSON to a NSDictionary so I can process it? 将(NSData或NSString)JSON转换为NSDictionary以便我可以处理的简单方法是什么?
Building for iOS4.3 Many Thanks, -Code 针对iOS4.3的构建非常感谢,-Code
Use this : 用这个 :
NSString *urlString = [NSString stringWithFormat:kURLString,self.chapter,self.page];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:[urlString dataUsingEncoding:NSISOLatin1StringEncoding]];
NSData* responseData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSISOLatin1StringEncoding];
NSDictionary* result = [(NSDictionary*)[responseString JSONValue] objectForKey:@"Result"];
I use SBJson 我用SBJson
NSArray *arrObj = (NSArray*)[[JsonParser sharedJsonParser] getObjectsFromJsonString:responseString];
response string is a JSON string here 响应字符串是JSON字符串

for (NSMutableDictionary *dic in jsonObject){
[nameArray addObject:[dic valueForKey:@"name"]];
