小编Spi*_*ire的帖子

我已经阅读了很多这方面的教程,我只是想知道这是否是正确的方法

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    NSLog(@"My token is: %@", deviceToken);

    NSData *urlData;
    NSURLResponse *response;
    urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil];

}

任何建议都受到欢迎.

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{

    const char* data = [deviceToken bytes];
    NSMutableString* token = [NSMutableString string];

    for (int i = 0; i < [deviceToken length]; i++) { …

    }

我在警报视图中有活动指示器,直到我的应用程序获得服务器响应时才会使用.应用程序将数据发送到服务器,警报视图显示,当服务器向我发送响应时如何关闭它.这是来自我的警报的代码

        [alert show];

        UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

        [indicator startAnimating];
        [alert addSubview:indicator];
