Question

In my universal app I have some images in Resources folder by the convention “image.png” “[e-mail]” etc.

When I change names of the images in the Resources folder I can see different images in the Simulator, But in real device whatever I do it keeps reading the previous image files. is there a cache mechanism or something do I need to clean or refresh about image files in Xcode3? Or I shouldn’t change image names in res folder?

This is how I read:

+(UIImage *) APP_CRYSTAL_SELECTION{
NSString *path = [[NSBundle mainBundle] pathForResource:@"cry" ofType:@"png"];
return [UIImage imageWithContentsOfResolutionIndependentFile:path]; 
}

Yes, caching might be at play here. To repopulate any imageView I always pass my imageView through a setup method –

- (UIImageView *)setupImageView:(UIImageView *)imgView flags:(UIViewContentMode) mode
{
    [imgView setImage:nil];
    [imgView setImage:[UIImage imageNamed:@"1pixel.gif"]];
    if(mode)
        [imgView setContentMode:mode];
    else if(mode == 0)
        nil; //no flags
    return imgView;
}

Basically I reset the view with a simple 1pixel Image, now it’s ready to be repopulated with any new image. hope this helps…
