IOS image carousel and start guide Interface

I used code4app.com to change his implementation method and use his image segmentation for reference in the starting guide interface.
Image carousel is a carousel I previously wrote. I set a timer to automatically set the next one.

Share it now

This is the guide Interface Usage

[Cpp]
-(BOOL) application :( UIApplication *) application didfinishlaunchingwitexceptions :( NSDictionary *) launchOptions
{
Self. window = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen] bounds];
Self. viewController = [[LKViewController alloc] initWithNibName: @ "LKViewController" bundle: nil];

NSMutableArray * dataArray = [NSMutableArray array];
For (int I = 1; I <= 5; I ++ ){
// Complete path for loading Images
[DataArray addObject: [[NSBundle mainBundle] pathForResource: [NSString stringWithFormat: @ "welcome-% d", I] ofType: @ "jpg"];
}
// How can I determine whether it is the first time I enter a file? How can I determine fields?
LKWelcomeView * welcome = [[LKWelcomeView alloc] initWithFrame: CGRectMake (0, 20, self. window. frame. size. width, self. window. frame. size. height-20) andPathArray: dataArray];

[Self. window addSubview: welcome];
Welcome. endEvent = ^ (){
// When you want to enter the main program
[Self. window insertSubview: self. viewController. view atIndex: 0];
};
 
[Self. window makeKeyAndVisible];
Return YES;
}

This is a simple method of carousel.

-(Void) viewDidLoad
{
NSMutableArray * pagearray = [NSMutableArray arrayWithCapacity: 5];
For (int I = 1; I <= 5; I ++ ){
[Pagearray addObject: [[NSBundle mainBundle] pathForResource: [NSString stringWithFormat: @ "page _ % d", I] ofType: @ "jpg"];
}

LKPageView * page = [[LKPageView alloc] initWithPathStringArray: pagearray andFrame: CGRectMake (0, 50,320,200)];
[Self. view addSubview: page];
[Super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
