Question

I want to make an wallpaper iphone app.
Now if i have for example 100 wallpapers , do I have to create 100 nib files and 100 .m and .h files and 100 UIButtons for to save the wallpaper and 100 UIButton for to go to the previous or next wallpaper ?
Is there any other way to do this ?
Thanks !

yes sure.
save your hundred wallpapers in the resources folder. The are named like this “wp_1.png”, “wp_2.png” etc.
Then you create a nib with the buttons (previous, next and save)
In the uiviewcontroller you’ll have an int property. For instance you call it n or something like that. I would suggest adding another property for your wallpaper (UIImageView) Then you implement the methods in the view controller.

-(void)awakeFromNib {
self.n = 1;
UIImage* wallpaper = [UIImage imageNamed:@"wp_1.png"];
UIImageView* view = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];
self.wallpaper = view;
view.image=wallpaper;
[self.view addSubview:view];
}

-(IBAction)next:(id)sender {
self.n++; // increases n by 1;
[self.wallpaper removeFromSuperview];
NSString* name = [NSString stringWithFormat:@"wp_%i.png", self.n];
UIImage* wallpaper = [UIImage imageNamed:name];
UIImageView* view = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];
self.wallpaper = view;
view.image=wallpaper;
[self.view addSubview:view];
}

something like that. hope that helps
