UIWebView not loading (mobile web page) sometime in iOS 9. I already used ATS bypass using NSAllowsArbitraryLoads.The issues not happening always and works well in iOS 7 and 8.
The delegate method webViewDidStartLoad invoked but webViewDidFinishLoad and didFailLoadWithError is not getting called at all.
Found the solution.All you need to do is remove UIWebView in iOS 9 and use WKWebView.My webpage had some third party calls to twitter,instagram etc which is https.Also I was getting Auth challenge in my webpage..! (Even I disabled the ATS).I found this by using WKWebView,which has the delegate to handle auth challenge.
Set the below delegate to get the auth challenge and handle it.
- (void)webView:(WKWebView *)webView
didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler
{
SecTrustRef serverTrust = challenge.protectionSpace.serverTrust;
CFDataRef exceptions = SecTrustCopyExceptions(serverTrust);
SecTrustSetExceptions(serverTrust, exceptions);
CFRelease(exceptions);
completionHandler(NSURLSessionAuthChallengeUseCredential,
[NSURLCredential credentialForTrust:serverTrust]);
}

We implement the Sign-In on iOS using the Google API in our project. Customers must have a possibility to select the HostedDomain to limit the allowed account pull to the single domain.
SignIn.SharedInstance.HostedDomain = "domainName.com";
works perfectly.
The problem is when we want to Logout the user and log in it back with unrestricted HostedDomain
SignIn.SharedInstance.HostedDomain == null; // <-Default Value
When I try to set it to
SignIn.SharedInstance.HostedDomain=string.empty;
I filter everything.
When I try to set it to null
SignIn.SharedInstance.HostedDomain=null;
I get the exception.
Calling:
SignIn.SharedInstance.Dispose();
doesn't help.
The question is: How is possible to reset the HostedDomain filtering to the initial stage - allow everything without of the app restart.
Our implementation based on Xamarin iOS native, but we see the same problem in Swift or Objective-C.
The wrapper for the Gooogle SDK we use:
Xamarin.Google.iOS.SignIn
Hi I have done with following steps to implement Universal Link for IOS.
1.My sub domain is npd.nowconfer.com, and my apple-app-site-association file contains,
{
"applinks": {
"apps": [],
"details": [
{
"appID":"R3UDJNSN2P.com.sampleUniversal.teledna",
"paths": ["*"]
}
]
}
}
this file is uploaded into my subdomain npd.nowconfer.com and its serveing over https.
2.I tested using AASA Validator i.e https://branch.io/resources/aasa-validator/#resultsbox and i got Test result as all pass.
you can see attached screenshot.
3.Now In app side,my colleague did configuration such as
Added the domain to Capabilities i.e applinks:nowconfer.com and applinks:npd.nowconfer.com
Handled Universal Links in app i.e in delegate like this
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *))restorationHandler {
NSURL *url = userActivity.webpageURL;
// handle url
}
4.my universalink is https://npd.nowconfer.com:5000/calendar/deeplink?url=nowconfer when i click on this link from email ,my app is not opening instead it is redirecting to app store(becasue server side request came handling to redirect app shore if app is not installed on device)
But when i tested universalink validator here https://search.developer.apple.com/appsearch-validation-tool ,i have got some error
Link to Application : Error no apps with domain entitlements
The entitlement data used to verify deep link dual authentication is from the current released version of your app. This data may take 48 hours to update.
I have seen lot of tutorials but not used anything for me.Can you guys help me to figure out what is happening here?
Universal Links have to be standard http:// or https:// links. This means they need to use the standard web ports, of which 5000 is not one. That is why your link is not working — it's not actually a valid Universal Link.
The Apple validator checks for some additional things, and is also somewhat unreliable. This particular error message is confusing, but it has nothing to do with whether your Universal Linking configuration is correct. What it actually means is Apple can't detect applinks: entitlements and 'proper' handling of passed-in link values in the version of your app that is currently live in the App Store. This is expected if you are just implementing Universal Links for the first time. You don't need to worry about this — a number of large and successful apps with working Universal Links implementations fail this step too.
I have developed a windows phone 8 application. Now I want to display vserv ads to my application.
I have added the sdk to my application and also applied code to show ads:
public MainPage()
{
InitializeComponent();
VservAdControl VMB = VservAdControl.Instance;
VMB.DisplayAd(zoneID, LayoutRoot);
VMB.VservAdClosed += new EventHandler(VACCallback_OnVservAdClosing);
VMB.VservAdNoFill += new EventHandler(VACCallback_OnVservAdNoFill);
}
void VACCallback_OnVservAdClosing(object sender, EventArgs e)
{
MessageBox.Show("Ad close by user.");
}
void VACCallback_OnVservAdNoFill(object sender, EventArgs e)
{
if (adGrid != null)
adGrid.Visibility = Visibility.Collapsed;
}
But after closing the ad the application page goes blank, all content, application bar automatically goes blank. After using back arrow that quits my application, i try to relaunch my application but application stuck at the splash screen on the emulator.
Wrap ad control inside a grid. Ad control could have manipulated the grid
I encountered the same issue and they have updated their SDK several times. If you provide the stacktrace they will provide you a fix.
Apart from what you have seen, there are other issues with the SDK. I integrated it few weeks back. So issues could have been resolved after that.
Memory leak. Click the ad or navigate back and forth - you will see the memory ever growing. This is because of events not being detached (withing SDK). I was consistently able to see my app crash in 512 MB emulator when banner ad is loaded (after 4 - 5 times). They could have used weak listeners. You might need to tweak a lot to overcome this issue (In multi page app)
RequestAdCallback throws null pointer exception sometimes crashing
the app. When people use app, they will navigate fast - forcing the
webbrowser to unload. All callbacks should be null pointer exception
free. Make sure that you handle unhandled exception globally otherwise app will not pass certification
It reads WMAppManifest.xml as text not as XML. So I had App element commented in first line before the actual one. It picked title from commented XML element
Application bar is manipulated in many events in the SDK. So you have to make sure that app bar is built dynamically. Test all navigation paths.
SDK assumes user will click the left arrow button which fires ad closing event. Try pressing phone back button instead. The app bar still disappears
SDK documentation requests app to demand ID_CAP_REMOVABLE_STORAGE capability. I don't see a reason to request this capability but I didn't add this
I have emailed them all these details. May be their latest SDK could have resolved these issues. But please do thorough testing after integration.
Add a function to load applicationbar using code
private void BuildLocalizedApplicationBar()
{
// Set the page's ApplicationBar to a new instance of ApplicationBar.
ApplicationBar = new ApplicationBar();
ApplicationBar.Mode = ApplicationBarMode.Default;
ApplicationBar.Opacity = 1.0;
ApplicationBar.IsVisible = true;
ApplicationBar.IsMenuEnabled = false;
// Create a new button and set the text value to the localized string from AppResources.
ApplicationBarIconButton button1 = new ApplicationBarIconButton();
button1.IconUri = new Uri("/Images/sms.png", UriKind.Relative);
button1.Text = "sms";
ApplicationBar.Buttons.Add(button1);
}
and then in VACCallback_OnVservAdClosing event handler call the function
BuildLocalizedApplicationBar()

I have encountered a weird bug with a released app. My UIWebView is no longer loading content on iOS 6, yet the content still displays in the simulator. The activity indicator displays properly but then it loads a blank url? Again, this only happens on a device, not on the simulator.
To provide extra context (in the simulator the NSURLRequest is assigned the proper URL. When run on a device the value is nil.)
Here is my code :
-(void)loading
{
if(!self.webView.loading)
[self.activityIndicator stopAnimating];
else {
[self.activityIndicator startAnimating];
}
}
- (void)viewDidLoad
{
[self.webView addSubview:self.activityIndicator];
NSURLRequest *requestUrl = [NSURLRequest requestWithURL:self.url];
[self.webView loadRequest:requestUrl];
self.timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:#selector(loading) userInfo:nil repeats:YES];
[super viewDidLoad];
NSLog(#"%#", requestUrl);
}
I had a similar issue with our web app (HTML+JS+CSS) not loading on a device, but working fine in a browser and iPhone Simulator. The cause of the issue was the wrong case in filenames. E.g., HTML file wanted to load a file 'Loader.js', whereas its name was 'loader.js'.
So, maybe you should check your 'self.url' (if your 'index.html' has the right case in its filename).
please use web view in nib and debug it to safari developer tools,
so you can trace the actual problem. I use this approach for my application and its working.
process to open developer tools
1-open safari
2-go to preference
3-go to advance option
4- set on to developer tools
After follow above process you can see your safari having option develop.
it means your safari developer tools is active and you can able to debug ios application
Anyone know if it's now feasible to launch the 'Settings' app from your app? Google Maps does it when you don't have Location Services enabled and you try to locate yourself.
I've seen lots of folks post about it and most answers point to adding a bug in Radar.
In the wild, I know of two apps that show this dialog with ""Turn on Location Services to Allow [app] to Determine Your Location" along side Cancel and Settings buttons where the 'Settings' button will take you to the General Settings.
1) Facebook app version 3.3.2 that runs on iOS 3.1.3 shows this alert on start. I looked at the three20 source code in git-hub but that project is not really a full source of the app but more of a library with the app's components.
2) GroupMe also shows the same alert when adding current location to a new message.
You mean the settings of the app like you see in settings?
First create a settings.bundle in xcode>newfile>settings.bundle.
This will create some prop lists that you can edit from out of the Settings.app or your app self. For the exact code Google can help you a lot further that I can. If you have any specific questions; don't hesitate to ask.
In iOS 5.0 you can open settings using the "prefs://" URL scheme. But in iOS 5.1 it doesn't work. But there is a trick I used for login twitter account using settings inside my app. the code is
TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init];
// Create the completion handler block.
[tweetViewController setCompletionHandler:^(TWTweetComposeViewControllerResult result)
{
[self dismissModalViewControllerAnimated:YES];
}];
// Present the tweet composition view controller modally.
[self presentModalViewController:tweetViewController animated:YES];
tweetViewController.view.hidden = YES;
for (UIView *view in tweetViewController.view.subviews){
[view removeFromSuperview];
}
Using this code you can switch to settings from your app directly if you are not already logged in twitter account.
