UIApplicationOpenSettingsURLString

I am facing the same problem opening the Settings app with below code, my app simply crashes while it is trying to open Settings app.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString] options:@{} completionHandler:nil];

What exactly is the crash you see? I just tried this in a test app and it seemed to work fine.

Thanks for the reply.

In my app I was trying to launch Apple "Settings" app with above-mentioned code it works fine on iOS 9.x.x and earlier, however on iOS 10.1.1 and 10.2, my app tries to launch and Apple "Settings" app in that process it goes into background and while Apple "Settings" app is about to launch it crashes

I am also facing same issue in iOS 10, when I try to open settings app from my app it will crash. here is the crash logs

Code:

NSURL *url1 = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

[application openURL:url options:@{} completionHandler:nil];

BSMachError: port 7f03; (os/kern) invalid capability (0x14) "Unable to insert COPY_SEND"

_BSMachError: port 7f03; (os/kern) invalid name (0xf) "Unable to deallocate send right"

but if I use NSURL *url = [NSURL URLWithString:@"App-Prefs::root=Settings"];

UIApplication *application = [UIApplication sharedApplication];

[application openURL:url options:@{} completionHandler:nil];

It works in iOS10

Do we have any resolution for this ? I am facing the same issue

Is there any bug logged with apple for the same ?

I would recommend people get bug reports written with a sample app showing the problem. When I tried this just recently it was working as expected so something funny is happening here.

sure. will do. shall I just paste the crash report for the sample app or u expect to share the code as well ?

Upload your crash report and sample code at https://bugreport.apple.com, and then post the bug report number here in this thread so Apple employees can find it.
