工作总结：

任务说明：使用GameCenter账户作为游戏的账户。需要在本地服务器上验证登入信息。

主要参考https://gist.github.com/andyzinsser/8044165网站代码。

1.登入后给自己游戏服务器发post请求确认数据信息

流程：登入GameCenter－通过generateIdentityVerificationSignatureWithCompletionHandler获取相关信息－

[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {        if (error) {            NSLog(@"ERROR: %@",error);        }        else        {            [[GKLocalPlayer localPlayer] generateIdentityVerificationSignatureWithCompletionHandler:^(NSURL *publicKeyUrl, NSData *signature, NSData *salt, uint64_t timestamp, NSError *error) {                if (error) {                    NSLog(@"ERROR: %@",error);                }                else{                    // package data to be sent to server for verification                    NSDictionary *params = @{@"public_key_url": [publicKeyUrl absoluteString],                                             @"timestamp": [NSString stringWithFormat:@"%llu", timestamp],                                             @"signature": [signature base64EncodedStringWithOptions:0],                                             @"salt": [salt base64EncodedStringWithOptions:0],                                             @"player_id": [GKLocalPlayer localPlayer].playerID,                                             @"app_bundle_id": [[NSBundle mainBundle] bundleIdentifier]};                    NSError *JSONError = nil;                    NSData *JSONPOSTData = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&JSONError];                    NSString *loginURL = /*your game sever*/;                    NSMutableURLRequest *postRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:loginURL]];                    [postRequest setHTTPBody:JSONPOSTData];                    [postRequest setHTTPMethod:@"POST"];                    NSOperationQueue *queue = [[NSOperationQueue alloc] init];                    [NSURLConnection sendAsynchronousRequest:postRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {                        if (error) {                            NSLog(@"HttpPostError%@",error);                        }                        else                        {                            NSInteger responseCode = [(NSHTTPURLResponse*)response statusCode];                            NSString *responseString = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];                            NSLog(@"HttpResponseCode:%d",responseCode);                            NSLog(@"HttpResponseString:%@",responseString);                        }                    }];                }                            }];        }    }];

2. NSDictionary 转 JSON

NSDictionary *params = @{@"public_key_url": [publicKeyUrl absoluteString],                                             @"timestamp": [NSString stringWithFormat:@"%llu", timestamp],                                             @"signature": [signature base64EncodedStringWithOptions:0],                                             @"salt": [salt base64EncodedStringWithOptions:0],                                             @"player_id": [GKLocalPlayer localPlayer].playerID,                                             @"app_bundle_id": [[NSBundle mainBundle] bundleIdentifier]};                    NSError *JSONError = nil;                    NSData *JSONPOSTData = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&JSONError];

2.JSON 转 NSString

NSString *JSONPOSTString = [[NSString alloc] initWithData:JSONPOSTData encoding:NSUTF8StringEncoding];

3.JSON 转 NSDictionary

NSError *error =nil;

NSDictionary *dic = [NSJSONSerializationJSONObjectWithData:data options:kNilOptions error:&error];
