1. Define Global member variables

@interface Appdelegate ()

@property (Strong, nonatomic) Uiimageview *adimageview;

@property (Strong, nonatomic) Uinavigationcontroller *rootnavi;

@end

2. Implement simple Advertising interface

@implementation Appdelegate

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: (Nsdictionary *) launchOptions {

Self.window = [[UIWindow alloc] Initwithframe:[uiscreen mainscreen].bounds];

textviewcontroller* MAINVC = [[Textviewcontroller alloc] init];

Uinavigationcontroller *nav = [[Uinavigationcontroller alloc] INITWITHROOTVIEWCONTROLLER:MAINVC];

Self.rootnavi = nav;

if ([[Uidevice currentdevice].systemversion Doublevalue] < 7.0) {

[Nav.navigationbar Setbartintcolor:[uicolor Clearcolor];

} else {

[Nav.navigationbar Settintcolor:[uicolor Clearcolor];

}

Note: Be sure to set the empty Rootviewcontroller

Uiviewcontroller *emptyview = [[Uiviewcontroller alloc] Initwithnibname:nil Bundle:nil];

Self. window. Rootviewcontroller = Emptyview;

Self.adimageview = [[Uiimageview alloc]initwithframe:cgrectmake (0, 0, ScreenWidth, screenheight)];

[Self.adimageview setimage:[uiimage imagenamed:@ "Bg_welcome"];

[Self.window AddSubview:self.adImageView];

[Self performselector: @selector (Removeadimageview) Withobject:nil Afterdelay:3];

Self.window.backgroundColor = [Uicolor Whitecolor];

[Self.window makekeyandvisible];

return YES;

}

3. Remove the ad page to reset the root controller

-(void) Removeadimageview

{

[UIView animatewithduration:0.3f animations:^{

Self.adImageView.transform = Cgaffinetransformmakescale (0.5f,0.5f);

Self.adImageView.alpha = 0.F;

} completion:^ (BOOL finished) {

[Self.adimageview Removefromsuperview];

Self.window.rootViewController = Self.rootnavi;

[Self RestoreRootViewController:self.rootNavi];

}];

}

-(void) Restorerootviewcontroller: (Uiviewcontroller *) Rootviewcontroller

{

typedef void (^animation) (void);

uiwindow* window = Self.window;

Rootviewcontroller.modaltransitionstyle = Uimodaltransitionstylecrossdissolve;

Animation Animation = ^{

BOOL oldstate = [UIView areanimationsenabled];

[UIView Setanimationsenabled:no];

Window.rootviewcontroller = Rootviewcontroller;

[UIView Setanimationsenabled:oldstate];

};

[UIView Transitionwithview:window

duration:0.5f

Options:uiviewanimationoptiontransitioncrossdissolve

Animations:animation

Completion:nil];

}

@end

4, if you need to achieve a countdown, skip only need to customize view to operate on OK
