SSL Error in Connection to Server through iPhone

I am trying to establish a HTTPS connection to a server using my app. But the connection fails due to following error

Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made." UserInfo=0x612eb30 {, NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?,, NSLocalizedDescription=An SSL error has occurred and a secure connection to the server cannot be made., NSUnderlyingError=0x612eb70 "An SSL error has occurred and a secure connection to the server cannot be made."}

The code to connect to server is

-(IBAction) handleEvents:(id)sender
    if ((UIButton*)sender == submit) {

    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

    NSData *urlData;
    NSURLResponse *response;
    NSError *error;

    NSString *url =[[NSString alloc]initWithFormat:@"%@signup",baseURL];
    NSURL *theURL =[NSURL URLWithString:url];
    NSMutableURLRequest *theRequest =[NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:0.0f];
    [theRequest setHTTPMethod:@"POST"];
    NSString *theBodyString = [NSString stringWithFormat:@"emailId=%@&mobileNumber=%@&appId=%@&password=%@&firstName=%@&lastName=%@"
                               ,@"",@"919879876780",@"bf1c7a6b3d266a7fe350fcfc4dda275211c13c23" ,@"qwerty" , @"Dev" , @"Sri"];
    NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding];

    [theRequest setHTTPBody:theBodyData];
    urlData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error];

my delegate methods are

- (void)handleError:(NSError *)error

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
  [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;   


- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge (NSURLAuthenticationChallenge *)challenge {  
    NSLog(@"check auth");
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];

I am stuck over here and could not find any way out.

Any form of help would be greatly appreciated.

thanks in advance!!


iOS 9 forces connections that are using HTTPS to be TLS 1.2 to avoid recent vulnerabilities. In iOS 8 even unencrypted HTTP connections were supported, so that older versions of TLS didn't make any problems either. As a workaround, you can add this code snippet to your Info.plist:


Thereby you're disabling the App Transport Security. Hope that's helpful.
