Question

I’m Developing an iPad application where I need to download file from the Webservice and I don’t want it affect any other process running on the foreground.

I am displaying the data from the local database in my app and also this data is coming from the web service.

Help Is Appreciated.

Thank You Very Much in advance.

Few thoughts:

1. you can run the download process on separate thread.

2. Write a class as below

@interface FileDownloader : NSOperation

//with following methods:

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:
                         [NSURLRequest requestWithURL:
                          [NSURL URLWithString:fileRecord.fileURLString]] delegate:self startImmediately:YES];
