Use a NSTimer. Move the UIImageView move everytime the timer ticks

What's the code to move the image? I mean what do I put in the -(void) That the timer is calling?

myImageView.frame = CGRectMake(myImageView.frame.origin.x, myImageView.frame.origin.y, myImageView.size.width, myImageView.size.height);

you must only increment the x, and when it is > Z, you will set to 0.

I am getting an error: request for member 'size' in something not a structure or union

With this code put in a -(void) that a timer is calling. Please Help Me!

four.frame = CGRectMake(four.frame.origin.x, four.frame.origin.y, four.size.width, four.size.height);

UIImageViews do not have a property called 'size'. CGRect does though, so

four.frame = CGRectMake(four.frame.origin.x, four.frame.origin.y, four.frame.size.width, four.frame.size.height);[/quote]

It's much easier to set up an animation block with SetAnimationRepeatCount = FLT_MAX. No NSTimer required!

I put the following codeine the -(void) that the timer calls. I got no errors but when I run the app it doesn't move a bit. I want it to go right to left.

four.frame = CGRectMake(four.frame.origin.x, four.frame.origin.y, four.frame.size.width, four.frame.size.height);

mmm.....try to undestand what are you doing.

you are setting a new frame for you view, it consist of a X (you know what it represent no?) a Y, a width (that not must change), and a height (that not must change). So maybe if you set the x of something as the old x, you will not see nothing move.

Let me google that for you

Wasn't that hard I don't think, there are tons of solutions. Videos from YouTube will probably be best. Most of them set the image moving across the whole screen. So you just need to set the coordinates to just go across the screen (or whatever you want).
