Wenn ich auf Jiris Antwort antworte, wird dich das ziemlich nahe bringen. Stellvertreter MTStatusBarOverlay mit CWStatusBarNotification. Um den modalen Übergang zwischen Ansichtscontrollern zu handhaben, verwende ich MusicPlayerTransition. Wir nehmen eine Bildansicht an: "art" in self.view mit frame: CGRect (0, 0, self.view.bounds.size.width, self.view.bounds.size.width). Muss ein wenig massieren, aber Sie bekommen das Wesentliche. Hinweis: Obwohl wir nicht "leben", sind die meisten, die wir jemals aus sind, eine Sekunde, und die Batteriefarbe ist nicht erhalten. Außerdem müssen Sie die Animationszeit in CWStatusBarNotification.m auf Null setzen. (notificationAnimationDuration-Eigenschaft)

#define kStatusTextOffset 5.4 // (rough guess of) space between window's origin.y and status bar label's origin.y

Um die Statusleiste Screenshots synchron mit der aktuellen Statusleiste zu halten, Setup Ihrer Timer. Feuern Sie es in viewWillAppear, und töten Sie es in viewDidDisappear.
-(void)setupStatusBarImageUpdateTimer{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
dispatch_async(dispatch_get_main_queue(), ^(){
// main thread
if (!statusTimer) {
statusTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(handleStatusTimer:) userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:statusTimer forMode:NSRunLoopCommonModes];
}
});
});
}
-(void)destroyStatusBarImageUpdateTimer{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
dispatch_async(dispatch_get_main_queue(), ^(){
// main thread
[statusTimer invalidate];
statusTimer = nil;
});
});
}
-(void)handleStatusTimer:(NSTimer*)timer{
UIWindow *statusBarWindow = [[UIApplication sharedApplication] valueForKey:@"_statusBarWindow"];
UIGraphicsBeginImageContext(CGSizeMake(self.view.bounds.size.width, 20));
[statusBarWindow.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
CGRect rect = CGRectMake(0, 0, self.view.bounds.size.width, 20);
CGImageRef imageRef = CGImageCreateWithImageInRect([viewImage CGImage], rect);
UIImage *statusImg = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);
statusImg = [statusImg imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
statusImgViewCopy.image = statusImg;
}
Weil wir einen starken Bezug auf den Timer und das Setup und die Entwertung geschieht auf dem gleichen Thread haben, gibt es keine Sorgen um den Timer zu entkräften scheitern. Das Endergebnis sollte wie folgt aussehen:
Nachdenken über privates API –
Image: Top weiß Teil die erste VC ist ein Teil mit weißen statusBar und Album-Cover ist ein weiterer VC (über dem ersten VC). –
Das Problem ist, dass die Statusleiste dunkle Farbe in der oberen Hälfte und helle Farbe im unteren Teil hat? –
