Trying to make my image's position change randomly

Question

I am using Xcode to try to change my images position randomly every time a button is pushed but for some reason, the image only moves once in a while when the button is pushed even though I know it received the button's IBAction because the NSLog in the IBAction displayed in the console, I have tried it two ways and both methods only worked sporadically

Method 1:

ranX = arc4random() %320;
ranY = arc4random() %480;
myImage.center = CGPointMake(ranX, ranY);

Method 2:

myImage.center = CGPointMake(arc4random() %320, arc4random() %480);

One more thing: every time it does work, the next IBAction to run puts it right back into its original position.

More information that might be pertinent I don't know, I do not have size classes enabled, it is triggered by touch up inside. I also DID make all the RNGs arc4random_uniform. The problem is fixed, just deselect auto layout.

not that its going to fix your problem, but you should use [arc4random_uniform()](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/arc4random_uniform.3.html) instead — Fonix, Mar 19 '15 at 03:47
what does it do? I know it has something to do with "modulo bias" but could you expand for my sake? — jose, Mar 19 '15 at 03:48

What control event did you add to your button? Since you stated it moves every once in a while, you might have done the wrong event. Try UIControlEventTouchUpInside So,

[myButton addTarget:self action:@selector(moveImage) forControlEvents:UIControlEventTouchUpInside];

You're using a storyboard I see, Make sure that the send event for the button is "Touch Up Inside". Click on the button, go to the Connections Inspector and double check this.

I did select touch up inside as the mode when I created the button and it gave the option – jose Mar 19 '15 at 03:49
Go to your Connections Inspector to see if it really was Touch Up Inside. – SpencerBaker Mar 19 '15 at 03:54
double checked, it is. Thanks though – jose Mar 19 '15 at 03:58
