objective-c - Displaying a Custom UIView on Springboard (Jailbreak)

Question

I created a custom UIView programmatically. Does anyone know what class and what method I would use to display this on the springboard? I want my UIView to display on the springboard, and when a user opens an app I want it to show up there too. I have been searching through the private headers for some time and I can't seem to find what I'm looking for. I am developing a jailbreak tweak with iosopendev. Also could you tell me if the class is a viewcontroller or just a view?

Answer 1

如果您希望 UIView 显示在任何地方（在 SpringBoard 和应用程序中），您应该在其他 UIWindow 上方创建一个新的 UIWindow 并在其中显示您的视图，如下所示：

UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.windowLevel = UIWindowLevelAlert + 2;
[window setHidden:NO];
[window setAlpha:1.0];
[window setBackgroundColor:[UIColor clearColor]];
[window addSubview:yourView];

Answer 2

您可以挂钩 SpringBoard 的一些方法，例如：

- (void)applicationDidFinishLaunching:(id)arg1

然后，您的代码应该是这样的：

- (void)applicationDidFinishLaunching:(id)arg1
{
    %orig;
    NSLog(@"----- applicationDidFinishLaunching -----");
    UIWindow *_uiwindow = [[UIWindow alloc] initWithFrame:CGRectMake(100,100,120,100)];
    _uiwindow.windowLevel = UIWindowLevelStatusBar;
    _uiwindow.hidden = NO;
    [_uiwindow setBackgroundColor:[UIColor redColor]];
}

要添加更多自定义视图，只需将子视图添加到_uiwindow. 希望对您有所帮助。
