add the following command parameter
--no-repo-update

so you should use:    pod update --verbose --no-repo-update

Apple Officially Disable the Settings URL Scheme Only Allow in Custom Keyboard Extension

Since iOS 10, iOS developer can not use URL Scheme to open Settings in their own iOS apps.


The reason is URL schemes for iPhone/iPad Settings are considered Private API which against the Apple Developer Guide.

iOS 10,  here is the only way to open settings in Apple iOS Developer's app:

Use the const string to open App's own setting:

In Swift:

UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)

In Objective-C

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

So don't waste time to search the solution for the "jump" or "redirect" users to specific settings with traditional way.


But one more interesting things: on  iOS 10 simulator, you can still working the "redirect" users to settings with the following method.




For more details: Apple Developer Technical Q&A QA1924

Reference Doc: Full List Of Settings URL schemes


FYI:

I am developing a Today Widget to open user's WiFi & Mobile Usage Settings, it really working fine on iOS 9 or earlier version and partially tested in iOS 10 beta Simulator with XCode 8.

When I prepare to publish this app on Apple Store, iOS 10 released, I tested my widget on my iPhone 5 16G real device, my nightmare coming. You can imaging how dark is it to me!!!

I searched on Google & stackoverflow one week try to find a solution. Until now, I wrote this article for those who want to do the same thing as me.

Don't Waste Time on Settings URL Scheme Solution!

Thank You Apple, you ruined my first app on Apple Store!

I quit my job to start a studio and try to make small system level app to improve user's experience.

Now it seem I should do another thing. how bad it is!

and my bad luck is not stopped, I purchased iPhone 6S for my mum, but the phone is broken, can not connect to WiFi and Bluetooth, I had to wait for returned from the apple repair factory.

Google Firebase Admob GADBannerView Fail to receive Ad

@property(nonatomic,strong)GADBannerView  *bannerView;

@end

@implementation ViewController

- (void)viewDidLoad {

   ....

    [GADMobileAds configureWithApplicationID:@"ca-app-pub-YYYYYYY~YYYYYYY"];

    _bannerView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];

    _bannerView.center = CGPointMake(self.view.center.x, _adSize.size.height/2.f + 44/2.f + 50/2.f);

    _bannerView.adUnitID = @"ca-app-pub-XXXXXXXXXX/XXXXXXXX";

    _bannerView.rootViewController = self;

    _bannerView.delegate = self;

    

    GADRequest * request = [GADRequest request];

    request.testDevices = @[kGADSimulatorID];

    [_bannerView loadRequest:request];

    [self.view addSubview: _bannerView];

}

#pragma mark - 

- (void)adViewDidReceiveAd:(GADBannerView *)bannerView {

    NSLog(@"Admob Ad was loaded and ready to be displayed");

}

- (void)adView:(GADBannerView *)bannerView didFailToReceiveAdWithError:(GADRequestError *)error {

    NSLog(@"Admob Ad failed to load");

}

Error:

Error Domain=com.google.ads Code=13 "Request Error: Received invalid response." UserInfo={NSLocalizedDescription=Request Error: Received invalid response., NSLocalizedFailureReason=Request Error: Received invalid response.}

Solution:

1. Make Sure your  adUnitID and ApplicationID are correct.

2. Add  request.testDevices = @[kGADSimulatorID]; 

3. iOS 9 or iOS 10 app please in Info.plist  add "App Transport Security Settings" - "Allow Arbitrary Loads" set to "Yes"

You will get the test ads

iOS 10 Today Extension(Today Widget) can not jump to WiFi settings.

Even if you can run the following code on iPhone simulator.

#pragma mark - Action

-(IBAction)actionSetting:(id)sender {

    NSURL * urlWiFiSetting = [NSURL URLWithString://@"prefs:root=WIFI"

                              @"prefs:root=MOBILE_DATA_SETTINGS_ID"

                              ];

    if (urlWiFiSetting) {

        [self.extensionContext openURL:urlWiFiSetting completionHandler:^(BOOL success) {

        }];

    } else {

        NSAssert(true, @"Not Support UIApplicationOpenSettingsURLString");

    }}

But when you run it on real device, you may get the following error:

2016-09-19 02:49:59.564568 Today Extension[4633:766201] __55-[_NCWidgetExtensionContext openURL:completionHandler:]_block_invoke failed: Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"

(lldb) 

iOS 10 Apple disable the shortcut for app to jump into.

No way to fix this issue, unless you can report a bug to Apple Bug Report system.
