在启用沙箱的OSX 10.10上创建应用程序默认处理程序

Question

I wasn't able to find anything online about this, but LSSetDefaultHandlerForURLScheme will return -54 when the sandbox is enabled. I'm not sure what entitlement needs to be turned on for this to work as it does without the sandbox on.

To see this in effect, create a new project with this in the appdelegate:

-(void)applicationWillFinishLaunching:(NSNotification *)notification {
    // Become default handler
    CFStringRef bundleID = (CFStringRef)CFBridgingRetain([[NSBundle mainBundle] bundleIdentifier]);
    OSStatus result = LSSetDefaultHandlerForURLScheme(CFSTR("maxel"), bundleID);
    if (result != 0) {
        assert(0);
    }
}

It will work. Next turn on sandbox. It will fail with -54 in result.

Built on OSX 10.10 Yosemite. Anyone else run into this?

According to Apple's developer forums, you can't do this anymore in the sandbox--the behavior you are seeing is expected. It's really aggravating, because no alternative API exists to implement this functionality, short of stepping outside of the sandbox.
