Question

I have app in which if there is data in local data base then it will first upload it to server before starting the application i have written the upload code in app Deleage I want that while uploading is going on how to show activiy indicator with alert.

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


     [self copyDatabaseIfNeeded];


     NSMutableArray *tempArray = [[NSMutableArray alloc] init];
     self.coffeeArray = tempArray;
     [tempArray release];

     [Coffee checkData:[self getDBPath]];


  int mytestcount=rowCount;
        NSLog(@"My Test ROw Count IS %d",mytestcount);


    if (mytestcount=0) {


    NSLog("No Data To Upload");

    }


   else {


    [Coffee getInitialDataToDisplay:[self getDBPath]];

    [self uploadData];
   }


   [self.window addSubview:[navigationController view]];

       [self.window makeKeyAndVisible];

       return YES;
      }

Displaying UIActivityIndicator for this operation requires putting it in didFinishLaunchingWithOptions of appDelegate. Perform uploading in different thread so that indicator is displayed as long as operation is carried out. The change will be as follows :

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

        [self copyDatabaseIfNeeded];
        NSMutableArray *tempArray = [[NSMutableArray alloc] init];
        self.coffeeArray = tempArray;
        [tempArray release];
        [Coffee checkData:[self getDBPath]];
        int mytestcount=rowCount;
        NSLog(@"My Test ROw Count IS %d",mytestcount);
        if (mytestcount=0) {
            NSLog("No Data To Upload");
        }
       else {
            [Coffee getInitialDataToDisplay:[self getDBPath]];
            //Set activity indicator here and perform uploading in different thread so that indicator is displayed as long as operation is carried out.  

           [self performSelector:@selector(uploadData) withObject:nil afterDelay:0];
       }
       [self.window addSubview:[navigationController view]];
       [self.window makeKeyAndVisible];
       return YES;
      }

Creating a UIActivityIndicator in an alert is not difficult task. You can do it as follows :

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@" " message:@" " delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[alert addSubview:progress];
[progress startAnimating];   
[alert show];  

You can customize your alert as you like it to be.
Hope this helps.
