如何在应用更新下载后再次调用didFinishLaunchingWithOptions

Question

我想知道如何在应用程序更新下载后再次调用didFinishLaunchingWithOptions,因为我的所有函数调用都在那里.

self.dataArray = [self readDataJsonFromDocument];当我从网上下载数据时,我需要再次调用它.

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


    [self   UIAppearances];    

    //first load
    [self copyJsonFromBundle];

    [self copyFolderFromBundle];

    self.dataArray = [self readDataJsonFromDocument]; //i need to call this again

    // Override point for customization after application launch.
    // Add the tab bar controller's current view as a subview of the window


    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    return YES;
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {



    //NSString *downloadFolder = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"download"];

    //save to a temp file
    NSString* filePath = [NSString stringWithFormat:@"%@/temp.zip", self.documentsDir];

    //download folder
    //NSString* downloadFolder = [NSString stringWithFormat:@"%@/download", self.documentsDir];

    [self.fileManager createFileAtPath:filePath contents:self.receivedData attributes:nil];

    ZipArchive *zipArchive = [[ZipArchive alloc] init];

    if([zipArchive UnzipOpenFile:filePath]) {

//      if ([zipArchive UnzipFileTo:downloadFolder overWrite:YES]) {
        if ([zipArchive UnzipFileTo:self.documentsDir overWrite:YES]) {

            //unzipped successfully
            NSLog(@"Archive unzip Success");
            [self.fileManager removeItemAtPath:filePath error:NULL];
            [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
        } else {
            NSLog(@"Failure To Unzip Archive");             
            [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
        }

    } else  {
        NSLog(@"Failure To Open Archive");
    }


    //[self performSelectorOnMainThread:@selector(didUpdate) withObject:nil waitUntilDone:YES];

    //Update Document File
    NSString *updateUTCPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"UTCDate"];
    NSDate *currentDate = [NSDate date];
    NSArray *array = [NSArray arrayWithObject:currentDate];
    [array writeToFile:updateUTCPath atomically:YES];

}

你想做什么？

你当然可以手动调用应用程序委托的didFinishLaunchingWithOptions方法的第二次,但它可能会更有意义,把所有你想要的功能做第二次到一个单独的函数被调用方式都该附加到您的下载更新委托方法和didFinishLaunchingWithOptions方法.
