iOS Make Buttons and Labels appear after some Time - ios

Question

Currently I am creating an App when you first launch it, there is some Introduction Text and 2 Buttons. 1 Button to skip the Tutorial and the other one to do the Tutorial. I want that these 2 Buttons and those Labels appear after a certain Time and with an Fade In animation. Could anyone give me some code examples? I already tried searching but the results weren't helpful for me.
I Updatet some Code. Now looks like this:
.h File:
#interface startViewController : UIViewController {
IBOutlet UIButton *notourb;
IBOutlet UIButton *tourb;
IBOutlet UILabel *welcomeLabel;
}
- (void)shownotourb;
- (void)showtourb;
- (void)showwLabel;
And the .m File (I will only show the code from the buttons because I figured out how to do the Labels in another way):
- (void)viewDidLoad
{
[super viewDidLoad];
[self performSelector:#selector(shownotourb) withObject:nil afterDelay:2.0];
[self performSelector:#selector(showtourb) withObject:nil afterDelay:2.5];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)shownotourb {
[UIView animateWithDuration:10.0
delay:1.0
options:UIViewAnimationCurveEaseInOut
animations:^ {
[self.view addSubview:notourb];
}
completion:^(BOOL finished){}];
}
- (void)showtourb {
[UIView animateWithDuration:10.0
delay:1.0
options:UIViewAnimationCurveEaseInOut
animations:^ {
[self.view addSubview:tourb];
}
completion:^(BOOL finished){}];
}

Answer 1

create a method which will add the buttons to the view, and use the performSelector:afterDelay method to add them like this:
in your viewDidLoad:
[self performSelector:#selector(addButtonsToView) withObject:nil afterDelay:5.0];
and add this method to add your buttons:
-(void)addButtonsToView
{
[UIView animateWithDuration:10.0
delay:1.0
options:UIViewAnimationCurveEaseInOut
animations:^ {
[self.view addSubview:button1];
[self.view addSubview:button2];
}
completion:^(BOOL finished){}];
}
hope it helps :)
