引導頁控制器使用代碼

    // Do any additional setup after loading the view.

    //1)切換窗口的根視圖控制器
    AppDelegate *app = (AppDelegate *)[UIApplication sharedApplication].delegate;
    app.window.rootViewController = app.sideMenu;
    //2)把當前版本號持久化
    [[NSUserDefaults standardUserDefaults]setObject:CURRENT_VERSION forKey:SAVED_VERSION];
    [[NSUserDefaults standardUserDefaults]synchronize];
}

無限輪播控制器使用代碼

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    NSArray *imgArr = @[@"man1.JPG",@"man2.JPG",@"man3.JPG",@"man4.JPG"];
    CGFloat scrW = [UIScreen mainScreen].bounds.size.width;
    
    ImageScrollView *imgScrView = [[ImageScrollView alloc]initWithFrame:CGRectMake(10, 100, scrW-20, 250) style:ImageScrollType_Banner images:imgArr confirmBtnTitle:nil confirmBtnTitleColor:nil confirmBtnFrame:CGRectNull autoScrollTimeInterval:3.0 delegate:self];
    
    [self.view addSubview:imgScrView];
    [imgScrView addPageControlToSuperView:self.view];
    //使用Scrollview與Navigation使用會出現坐標位置不齊,所以使用以下方法可調整
    self.edgesForExtendedLayout = UIRectEdgeNone;

    

}
- (void)bannerImageDidHandleWithIndex:(NSInteger)index
{
    NSLog(@"===%ld",index);
}

導航條與UIScrollView沖突解決方法

（1）在添加UIScrollView的ViewController中添加代碼
self.edgesForExtendedLayout = UIRectEdgeNone;
（2）在添加UIScrollView的ViewController中添加代碼
self.automaticallyAdjustsScrollViewInsets = YES;
（3）如果以上兩種方法都不可以解決，使用下面方法：
在添加UIScrollView的ViewController中添加代碼：
UIView *v = [[UIView alloc] init];
[self.view addSubview:v];
然后再正常添加UIScrollView即可
