iOS app 如何添加引导页。

以下是通过UIScrollView实现的引导页。

#import "AppDelegate.h"

#import "ViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

ViewController *viewController = [[ViewController alloc] init];

self.window.rootViewController = viewController;

[self.window makeKeyAndVisible];

return YES;

}

end

封装的引导页 RunPageController.h 文件

#import <UIKit/UIKit.h>

@protocol RunPageControllerDelegate <NSObject>

-(void)OnButtonClick;

@end

@interface RunPageController : UIView

@property id<RunPageControllerDelegate>delegate;

@end

引导页 RunPageController.m 文件

控制器实现的代码。
