Question

我有以下代码，我想让它同步。我遇到的问题是，当我的api被调用时，我的程序继续，并且nil数据值在平均时间内传递。感谢您提前获得所有帮助。 \

{ - （IBAction）Make_Payment：（id）sender {

NSString *temp2 = [NSString stringWithFormat:@"{\n  \"partner_key\": \"%@\",\n  \"auth_token\": \"QaU9QcFZ6xE7aiRRBge0wZ4p6E01GEbl\",\n  \"payment_account_id\": \"%@\",\n  \"card_number\": \"%@\",\n  \"card_exp_date\": \"%@\",\n  \"amount\": \"%@\",\n  \"memo\": \"%@\",\n  \"recipient\": {\n    \"email\": \"%@\",\n    \"mobile_phone\": \"%@\"\n  }\n}",[Partner_Key text], [Payment_Account_ID text], [Card_Number text], [Card_Exp_Date text], [Amount text],[Memo text], [Recipient_Email text], [Recipient_Phone_Number text]];

NSLog(temp2);

NSNumber *errorCode    = nil;
NSString *errorMessage = nil;
NSString *guid1         = nil;
NSString *exponent     = nil;
NSString *modulus      = nil;

NSURL *URL = [NSURL URLWithString:@"https://cert.payzur.com/payzurservices.svc/payment/send/initiate"];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request setHTTPMethod:@"POST"];

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:[temp2 dataUsingEncoding:NSUTF8StringEncoding]];




NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:URL] completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
    if(error && failure)

使用NSURLSession的完成块。您要执行的活动，只需在完成块中执行。确保在NSURLSession的完成块中执行某些UI任务时，在主线程上执行它们。

-(void)sendRequestForURL:(NSString*)urlString Success:(void(^)(NSData *data))success Failure: (void(^)(NSError *error))failure
    {
        NSURLSession *session=[NSURLSession sharedSession];
        [[session dataTaskWithURL:[NSURL URLWithString:urlString] completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
            if(error && failure)
            {
                dispatch_async(dispatch_get_main_queue(), ^{
                    failure(error);
                });
            }
            else if(success)
            {
                dispatch_async(dispatch_get_main_queue(), ^{
                     success(data);
                });
            }

        }] resume];
    }
