iphone download several files
- by Floo
hi all !
In my app i need to download several plist.
to download a plist i use the NSURLconnection
in my code i use an UIAlertView with a UIActivityIndicator then when the download is finished i add a button to the alert to dismiss it.
To download the plist i use somewhere in my code an NSURL set to the adresse where the plist is, next i set a NSURLRequest with the url cache policy and a timeout interval.
Then i set my NSMutableData to the NSURL connection with a NSURLRequest.
In the delegate didReceiveData: i append data to my mutable data object, in the didFailWithError: i handle error. And finaly in the connectionDidFinishLoading i serialize my data to a plist so i can write to file my plist, and release my alertview.
My problem is : how can i do if i have sevetal file to download because the connectionDidFinishLoading is called each time my NSURLConnection is finished but i want to release my UiAlert when everything is finished. But when the first plist is downloaded my code in the connectionDidFinishLoading will fire.
here is my code :
in the view did load :
// set the UiAlert in the view did load
NSURL *theUrl = [NSURL URLWithString:@"http://adress.com/plist/myPlist.plist"];
NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
self.plistConnection = [[ NSURLConnection alloc] initwithRequest:theRequest delegate:self startImmediatly:YES];
//plistConnection is a NSURLConnection
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[incomingPListData appendData:data];
}
-(void)connection:(NSURLConnection *)connectionDidFailWithError:(NSError *)error {
// handle error here
}
-(void)connectionDidFinisloading:(NSURLConnection *) connection {
NSPropertyListFormat format;
NSString *serialErrorString;
NSData *plist = [NSPropertyListSerialisation propertyListFromData:incomingPlistData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&serialErrorString];
if (serialErrorString) {//error}
else { // create path and write plist to path}
// change message and title of the alert
so if i want todownload an another file where do i put the request the connection and how can i tell the didFinishLoading to fire code when all my file are downloaded.
thanks to all
