Я пытаюсь загрузить http://www.vesseltracker.com/earth/vesseltrackerlight.kmz, но не получаю все кусочки.
Я пытался:
NSData *data = [NSData dataWithContentsOfURL: serverURL options: 0 error: &error];
безрезультатно
затем переключился на
- (void)startDownloadingURL:(NSURL*) url
{
// Create the request.
NSURLRequest *theRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// create the connection with the request
// and start loading the data
NSLog(@"SNNetworkController.startDownloadingURL [%@]", url);
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
// Create the NSMutableData to hold the received data.
// receivedData is an instance variable declared elsewhere.
receivedData = [[NSMutableData data] retain];
} else {
// inform the user that the download failed.
NSLog(@"SNNetworkController.startDownloadingURL Download failed!");
}
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
// This method is called when the server has determined that it
// has enough information to create the NSURLResponse.
// It can be called multiple times, for example in the case of a
// redirect, so each time we reset the data.
// receivedData is an instance variable declared elsewhere.
[receivedData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
// Append the new data to receivedData.
// receivedData is an instance variable declared elsewhere.
[receivedData appendData:data];
}
- (void)connection:(NSURLConnection *)connection
didFailWithError:(NSError *)error
{
// release the connection, and the data object
[connection release];
// receivedData is declared as a method instance elsewhere
[receivedData release];
// inform the user
NSLog(@"SNNetworkController.didFailWithError Download failed! Error - %@",
[error localizedDescription]);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
// do something with the data
// receivedData is declared as a method instance elsewhere
NSLog(@"SNNetworkController.downloadDidFinish Succeeded! Received %d bytes of data",[receivedData length]);
// release the connection, and the data object
[connection release];
[receivedData release];
}
Но мне не повезло.Он всегда занимает 567 байт (должно быть около 4 КБ). Я думаю, что он может начать распаковываться и давать сбой ....
