版本判斷:

　　　　1.首先你要知道這個索引值對的key:id key =   (id)kCFBundleVersionKey;

　　　　2.同過本地的NSBundle取得當前的版本號碼。

　　　　3.在沙箱中取得對應的版本號碼。

　　　　4.比較來判斷載入情況。

    //首先擷取目前的版本，從plist中擷取    //在bundle中尋找擷取當前對應的version    id key =   (id)kCFBundleVersionKey;    NSDictionary *infoDictionary=[NSBundle mainBundle].infoDictionary;    NSString *currentVersion = [infoDictionary objectForKey:key];        //從沙箱擷取的bundle    NSUserDefaults *defaults= [NSUserDefaults standardUserDefaults];    NSString *defaultVersion = [defaults objectForKey:key];    if ([defaultVersion isEqual:currentVersion]) {       self.window.rootViewController = [[CSMainBarController alloc]init];    }else    {        CSLaunchView *indexView = [[CSLaunchView alloc]init];        self.window.rootViewController = indexView;    }

1.建立新的類來載入對應的圖片。通過UIViveController上套著UIScrollView再套上一個view.

2.載入對應的view

3.載入對應的pagecontroller
