CALayerInvalidGeometry', reason: 'CALayer bounds contains NaN: [0 0; nan nan] crash in view
According to the stack trace the problem is here
imageView_A.frame = CGRectMake(300, 200, 3.86, 3.86);Try to set the imageView_A.transform to identity. Another solution (and I think better) would be using the UIScrollView for scaling (it is also could be made animated).
Edit: try this
imageView_A.image = [UIImage imageNamed:[attractList_A objectAtIndex:imageIndex_A]]; imageView_A.frame = CGRectMake(300, 200, 3.86, 3.86); imageView_A.center = CGPointMake(attractLocs_x_A[attractLocs_A_index], attractLocs_y_A[attractLocs_A_index]); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2]; imageView_A.alpha = 1; imageView_A.frame = CGRectMake(300, 200, 386.0f, 386.0f); [UIView commitAnimations];
