Obj-c: moving an image view

I’m trying to simply move an image view from right to left starting at position 0, 0 and ending at -280, 0 but I can’t seem to get the code working…

in the viewController .h file

IBOutlet UIImageView *testbg;

in the .m

  • (void)viewDidLoad {

    //move background image
    int i;
    int newX;
    NSLog(@“%d”, testbg.center);

    for(i=0; i < 280; i++) {
    newX = i*-1;
    [UIView beginAnimations:@“test” context:NULL]; //context is not needed in this example. Also, it’s good to name your animation.
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDuration:0.1];
    [UIView setAnimationDidStopSelector:@selector(theAnimationDidStop:finished:context:)];
    testbg.center = CGPointMake(newX, 0);
    [UIView commitAnimations];

    [super viewDidLoad];

doesn’t break but doesn’t work either.
