Question

运行我的应用时遇到问题。当我将我的xcode版本升级到7.2时，我的应用程序在xcode 6.4中成功运行它无法连接到我的webservise。我想用webservice中的数据填充位置列表。我已经调试了我的代码，但它总是转到连接错误状态。这是我的代码：

- (void) locatoins {

    NSString *urlString = @"http://41.128.183.109:9090/api/Data/Getalllocations";

    NSURL *url = [NSURL URLWithString:urlString];

    NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:20];

    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

        if (connectionError) {
            [SVProgressHUD dismiss];
            LocationsViewController *D;
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Request Time Out"message: @"Network Connection Error"delegate: D cancelButtonTitle:@"Dismiss"otherButtonTitles:@"Cancel",nil];

            [alert setTag:1];


        } else {

             NSArray *json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];

            NSMutableArray *result = [NSMutableArray array];

            for (NSDictionary *obj in json) {

                Location *location = [[Location alloc] initWithDictionary:obj];
                [result addObject:location];
            }

            [self.delegate dataHandlerDidFininshGettingLocations:result];
        }
    }];
}

请告知。

您是否也在控制台中收到错误消息“CFNetwork SSLHandshake failed”？我认为这可能是一个ATS问题。 iOS 9（因此，Xcode 7）强制您使用https而不是http，并且您的服务器应该具有有效的ssl证书。

您可以通过在Info.plist文件中添加例外或通配符来绕过App Transport Security：

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>

或

<key>NSAppTransportSecurity</key>
<dict>
  <!--Include to allow all connections (DANGER)-->
  <key>NSAllowsArbitraryLoads</key>
      <true/>
</dict>
