以下是通过UIScrollView实现的引导页。

@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;
