Title: [Objective-C] help - UIImageView
Post by: AllusionOfIllusion on January 21, 2013, 02:25:32 AM

Hey guys, so I wasn't too sure if this could be placed here (if it has to get moved/deleted, I'll do it) but on my way to learning programming better, I've been working on an iOS application (mobile app creation that I maybe could use later haha). Anyway, I've been having some trouble trying to get an UIImage to reveal itself (it's set to hidden (from the storyboard viewer) but after a certain event (an if statement) I would like for it to pop up and be viewable to the user.


Code:

Code: [Select]

if(isWordComplete) {         //this is where I believe code should call the image from a "hidden" state
        [myDisplay setHidden:YES];
        [myDisplay2 setHidden:YES];
        [myDisplay3 setHidden:YES];
        [myDisplay4 setHidden:YES];
        [myDisplay5 setHidden:YES];
        [myDisplay6 setHidden:YES];
        [myDisplay7 setHidden:YES];
        [self checkNumberofWordsUserCompleteInLevel:isWordComplete];
        [self moveToNextWord];
 
    }
I feel like I've tried everything with UIImageView but nothing seems to be working...maybe someone can point me in the right direction. Thanks in advance for any help!

Maybe if you

Code: [Select]

[image setHidden:NO]... but I don't know.

Ask StackOverflow.
Maybe try coding in HTML (and use WebKit)?

Thanks! I actually looked into it, and you were right. I was apparently having one of those days where you stare at it for hours, then realize you need 2 lines of code and it works haha

Ideally you'd use some of the core animation stuff to do this btw.  Your approach works but its rather unclean and could look better.  I suggest looking into core animation and quartz

+1

I usually use UIViewAnimationCurveEaseOut to a make view appear / disappear smoothly but you have other options.
