Set Time from one ViewController to one ViewController

My App crashed because I set time from one ViewController to one ViewController in AppDelegate.m for method below and it show the message : unrecognized selector sent to instance 0x6a0e360. 

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [self performSelector:@selector(toSecondViewController:) withObject:nil afterDelay:5];
}

-(void)toSecondViewController{
    SecondViewController *second = [[SecondViewController alloc] init];
    [self.navigationController pushViewController:sale animated:YES];
}

I don't know why ?

If you want to send any parameter then only you should add ":". Otherwise there is no need to add.

So the correct code is- [self performSelector:@selector(toSecondViewController) withObject:nil afterDelay:5];

try change code

[self performSelector:@selector(toSecondViewController:) withObject:nil afterDelay:5];

to 

[self performSelector:@selector(toSecondViewController) withObject:nil afterDelay:5];

If func is not have any parameter, then don't add ":" symbol after func name
