ios - How do I make a button stay pressed?

Question

Okay so I have an app I'm building that is almost complete. I'm just having one problem, when I press my button it makes a sound and the button's image changes. However the image only changes when it is being touched or "highlighted" and I would like the buttons image to remain changed through the duration of the sound effect then after the sound effect I would like it to revert back to the original image. Is there anyway I can set up a UIButton "set time" or something for the "highlighted" option?

I feel so embarrassed sometimes, because I seem to get tripped up by these most trivial things, when I handle the core coding exceptionally well and near finish a full app in a days time, but this is my first app and I'm still a newbie to XCode. I really appreciate this community's help any answer that pushes me forward is always appreciated!

I further apologize for my questions formatting I typed this on my iPhone I hope it's not too awkward or lacking in detail. If anyone needs more detail just ask!

Put an image in button's attribute selected image in the XIB and when pressed

[(UIButton *)[self.view viewWithTag:buttonTag] setSelected:Yes];
