新特性展示

1.新特性声明时候的两种方法

 

//    //添加window的根视图控制器，UITabBarController

//    

//    if (![[NSUserDefaults standardUserDefaults]boolForKey:@"1"]) {

//        [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"1"];

//        NewFeatureController * newFeature=[[NewFeatureController alloc] init];

//        self.window.rootViewController=newFeature;

//        [newFeature release];

//        

//    }

//    

//    else{

//        TarbarViewController * tabBarVC = [[TarbarViewController alloc] init];

//        self.window.rootViewController = tabBarVC;

//        [tabBarVC release];

//        

//    }

    

    NSString *key = @"CFBundleVersion";

    // 取出沙盒中存储的上次使用软件的版本号

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    NSString *lastVersion = [defaults stringForKey:key];

    

    // 获得当前软件的版本号

    NSString *currentVersion = [NSBundle mainBundle].infoDictionary[key];

    if ([currentVersion isEqualToString:lastVersion]) {

        // 显示状态栏

//        [UIApplication sharedApplication].statusBarHidden = NO;

        [UIApplication sharedApplication].keyWindow.rootViewController = [[TarbarViewController alloc] init];

    } else { // 新版本

        [UIApplication sharedApplication].keyWindow.rootViewController = [[NewFeatureController alloc] init];

        // 存储新版本

        [defaults setObject:currentVersion forKey:key];

        [defaults synchronize];

    }

 

 

2.新特性的代码

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view.

    

    // 1.添加UISrollView

    [self setupScrollView];

    

    // 2.添加pageControl

    [self setupPageControl];

    

}

    CGFloat centerY = self.view.frame.size.height - 30;

    pageControl.center = CGPointMake(centerX, centerY);

    pageControl.bounds = CGRectMake(0, 0, 100, 30);

    pageControl.userInteractionEnabled = NO;

    [self.view addSubview:pageControl];

    self.pageControl = pageControl;

    

    // 2.设置圆点的颜色

    pageControl.currentPageIndicatorTintColor = SZColor(253, 98, 42);
