我在服务器上注册设备数据,以获取推送通知。这里是代码,
[NSURLConnection sendAsynchronousRequest: request
queue: _postQueue
completionHandler: ^(NSURLResponse *response, NSData *responseData, NSError *connectionError) {
if (connectionError) {
//
} else {
NSError *error = nil;
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData: responseData options: NSJSONReadingMutableContainers error: &error];
}
}];
我收到错误
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x17057f60 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
有人可以帮忙解决这个问题吗?
