Xcode：带有 UIButton 的壁纸

发布于 2024-10-21 13:20:56 字数 156 浏览 10 评论 0原文

我想制作一个 iPhone 壁纸应用程序。现在，如果我有 100 张壁纸，我是否必须创建 100 个 nib 文件、100 个 .m 和 .h 文件以及 100 个 UIButton 来保存壁纸和 100 个 UIButton 来转到上一个或下一个壁纸？还有其他方法可以做到这一点吗？谢谢！

是的，当然。
将您的一百张壁纸保存在资源文件夹中。其名称如下“wp_1.png”、“wp_2.png”等。
然后用按钮（上一个、下一个和保存）创建一个笔尖
在 uiviewcontroller 中，您将有一个 int 属性。例如你称它为 n 或类似的东西。我建议为您的壁纸添加另一个属性（UIImageView）然后您在视图控制器中实现这些方法。

-(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];
}

类似的事情。希望有帮助

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
