Custom URL schemes ios 9 - ios

Question

Alright I think I am close to a solution here. I think I must be missing something small. Hope you guy can help.'
I am trying to have another app open another custom app and run a method from that app that is being called through the URL scheme. I understand that in ios 9 they made it manitory to define in the info.plist the key
<key>LSApplicationQueriesSchemes</key>
<array>
<string>URLScheme0</string>
<string>URLScheme1</string>
<string>URLScheme2</string>
ect....
</array>
And I think I have done that properly. Though I want a confirm on this and other thing. Firstly, do I add this to the info.plist of the "calling" app, or the "receiving" app, or BOTH? As, I have it now it is with both. When I remove it from the calling apps plist I get the error.
"This app is not allowed to query for scheme xxx”
Keep in mind I have also included in the plist for the receiving app the URL types and URL schemes array with the same scheme names.
The the calling app I have a button mapped with this methods code:
- (IBAction)killMethod:(id)sender {
NSString *customURL = #"TurnOffRelay://";
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:customURL]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
} else {
UIAlertController* alert = [UIAlertController alertControllerWithTitle:#"URL error" message:#"No custom URL defined for Kill Relay" preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:alert animated:YES completion:nil];
}
}
and for the receiving app I have in the appDelegate.m :
- (BOOL)application:(UIApplication *)application OpenURL:(NSURL *)url sourceApplication:(NSString *) sourceApplication annotation:(id)annotation {
NSLog(#" Calling application: %#", sourceApplication);
NSLog(#"URL scheme: %#", [url scheme]);
if ([sourceApplication isEqualToString:#"net.ble.relay"]) {
if ([[url scheme] isEqualToString:#"TurnOffRelay://"]) {
ViewController *viewController = [[ViewController alloc] init];
[viewController killSwitch];
NSLog(#"Running killSwitch");
}
return YES;
}
else
return NO;
}
With what I have right now running I am able to actually press the button in the "calling" app and from there the "receiving" app opens, but alas, the method I want to run doesn't run inside of the if statements. I am wondering what I am doing wrong. I will gladly answer any questions about things I may have missed. This has been bothering me all day. Would like some sort of guidance. Thanks in advance.

Answer 1

pay attention to if ([[url scheme] isEqualToString:#"TurnOffRelay://"]) 。 url scheme is TurnOffRelay rather than TurnOffRelay://.

Answer 2

So, after changing the OpenURL to openURL and then noticing that the sourceApplication name was wrong. I am guessing that if I had typed in the correct application to use, as in, the actual name of the application that was "calling" the If block would have proceeded correctly. But I am sure, also, that if I had not changed the openURL I would have been stuck again.
Thanks for the help. Its now working as intended.
