我有我的代碼我創建啓動屏幕的時間間隔的問題。當它在視圖頂部執行時，會出現一個導航欄。現在我想隱藏那個導航欄。我如何刪除該閃屏？如何從啓動畫面中刪除導航欄？
- (void)loadView {
// Init the view
//CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
CGRect appFrame = CGRectMake(0, 0, 320, 480);
UIView *view = [[UIView alloc] initWithFrame:appFrame];
view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
self.view = view;
[view release];
splashImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"LS.jpg"]];
splashImageView.frame = CGRectMake(0, 44, 320, 460);
[self.view addSubview:splashImageView];
viewController = [[Menu alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:viewController];
viewController.view.alpha = 0.0;
[self.view addSubview:nc.view];
timer = [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(fadeScreen) userInfo:nil repeats:NO];}
-(void) onTimer{
NSLog(@"LOAD");
}
- (void)fadeScreen{
[UIView beginAnimations:nil context:nil]; // begins animation block
[UIView setAnimationDuration:0.75]; // sets animation duration
[UIView setAnimationDelegate:self]; // sets delegate for this block
[UIView setAnimationDidStopSelector:@selector(finishedFading)]; // calls the finishedFading method when the animation is done (or done fading out)
self.view.alpha = 0.0; // Fades the alpha channel of this view to "0.0" over the animationDuration of "0.75" seconds
[UIView commitAnimations]; // commits the animation block. This Block is done.
}
- (void) finishedFading{
[UIView beginAnimations:nil context:nil]; // begins animation block
[UIView setAnimationDuration:0.75]; // sets animation duration
self.view.alpha = 1.0; // fades the view to 1.0 alpha over 0.75 seconds
viewController.view.alpha = 1.0;
[UIView commitAnimations]; // commits the animation block. This Block is done.
[splashImageView removeFromSuperview];
}
如何在上面的代碼中使用defualt .png圖片？ – ram
你甚至不需要視圖控制器。看到我更新的答案。 – EmptyStack
這是「默認」而不是「Defualt」 – Pripyat
