Question

I have a question regarding Xcode.
I found a tutorial on the net that allowed me to move an image around the screen.
Could you please explain how I can make my button move to the left and back to right with one click (I can’t find this anywhere…), and immediately after that run another IBAction that allows me to switch to another subview? (I already have this code naturally…). I tried to add both IBActions in 1 centralized one, but it didn’t seem to work 🙁 It opens in this case immediately the subview without showing me the animation.

What I tried:

The code obtained until now:

-(IBAction) aMove: (id) sender{

    if (bMove == NO) {

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:1.0];
        btnTarget.transform = CGAffineTransformMakeTranslation(-30,0);
        [UIView commitAnimations];
        bMove = YES;

    }else{

        btnTarget.transform = CGAffineTransformIdentity;
        bMove = NO;

    }

}

-(IBAction) aAnimateActivate: (id) sender {

    [self aMove:nil];
    [self targetOpenView:nil]; //Opens the subview

}

I appreciate your help! Thanks!

concatenate works to combine animations and I just put two blocks of animations (two of the one shown below) after each other… :

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.3];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

CGAffineTransform transform = CGAffineTransformConcat(CGAffineTransformMakeScale(1, 1),CGAffineTransformMakeTranslation(10, -50));       
btnGuide.transform = transform;
[btnGuide setAlpha:0.0];

[UIView commitAnimations]; 

Basically implementing this code did the trick… Easy!
However… I needed some additional pieces of code for the further implementation such as:

[self performSelector:@selector(aGuide) withObject:self afterDelay:0.0];

(don’t mind the selector name)
and:

[NSTimer scheduledTimerWithTimeInterval:.5 target:self selector:@selector(targetOpenView:) userInfo:nil repeats:NO];
