iphone - 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更新下载后再次调用 didFinishLaunchingWithOptions，因为我所有的函数调用都在那里。

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

- (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？

您当然可以手动第二次调用您的 App Delegate 的 didFinishLaunchingWithOptions 方法，但将所有功能放在一起可能更有意义你想在一个单独的函数中完成第二次，该函数由 both 附加到你的下载更新方法和 didFinishLaunchingWithOptions 方法的委托(delegate)调用。
