Help! I cant find whats wrong. My code is up and mostly running and i needed to incorporate Urban Air push notification and there is something wrong with my code. If there is a better or different way to incorporate this that works without my errors I would appreciate that. I took this code from a tut of Urban Airmail. I wasnt sure what to inlude and what not to from the sample app. Now for my code. Ill notate where I get errors They are stray / errors and expected ; b4 : errors
If you could fix the code that would be awesome!

New Code that has troubles:
//Register for notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert)];
;}}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)_deviceToken {
//ERROR HERE Wrong type argument to unary minus and semi colon b4
回答1:
Doesn't look like you ever ended your application:didFinishLaunchingWithOptions: method - you should have an end brace after this line:
[[UIApplication sharedApplication] registerForRemoteNotificationTypes...
So it should look like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert)];
//ERROR HERE in line above Stray 357
}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)_deviceToken {
...
}
That should do it.
For your second code block - without seeing the surrounding code it's difficult to see what you're trying to do...you likely shouldn't have:
;}}
It should probably just be:
}
回答2:
If you are looking for unbalanced parentheses, then this is probably the part that is giving you troubles:
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
}
}
