使用ASIHTTPRequest

Question

我不知道是否有人可以幫我解決問題如何保持INAPP購買下載當設備進入睡眠模式使用ASIHTTPREQUEST時，我做了一個應用程序，其中包含一些音樂文件在應用程序中購買和下載，但是如果用戶購買並開始下載相冊，例如，如果他的手機在睡覺，它會停止下載！ 與欣賞方面的任何意見，

-(void) downloadAlbum:(NSNumber *)Albumid { 
//NSLog(@"%@",Albumid); 
//myTable.scrollEnabled = NO; 
[[UIApplication sharedApplication] setIdleTimerDisabled:YES]; 

if (CurrentSongID<=CurrentAlbumCount) { 
    if (isDownload==FALSE) {  

     Reachability* internetReach = [[Reachability reachabilityForInternetConnection] retain]; 
     [internetReach startNotifier]; 
     NetworkStatus netStatus = [internetReach currentReachabilityStatus]; 

     switch (netStatus) 
     { 
      case NotReachable: 
      { UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Top 10" message: @"Check Internet Connectivity" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil];
