Body
copied!<p>I'm having a problem here:</p> <p>I have a C function:</p> <pre><code>int my_connect(int sockfd, const struct sockaddr *serv_addr, socklen_t addrlen) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; alertViewDelegate = [FirewallRest alloc]; [alertViewDelegate retain]; //ALog(@"1"); int error; //ALog(@"2"); char hostname[NI_MAXHOST] = ""; //ALog(@"3"); error = getnameinfo(serv_addr, addrlen, hostname, NI_MAXHOST, NULL, 0, 0); //ALog(@"4"); if (error !=0) { ALog(@"coudldn't resolve hostname or internal connect"); [pool release]; return orig__connect(sockfd, serv_addr, addrlen); } if (error == 0) { ALog(@"hostname: %s", hostname); NSString *hostFirst = [NSString stringWithCString:hostname]; NSString *host = [hostFirst stringByReplacingOccurrencesOfString:@"www." withString:@""]; NSString *msg = [@"tries to contact: " stringByAppendingString:host]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"asdf" message:msg delegate:alertViewDelegate cancelButtonTitle:@"Never allow!" otherButtonTitles:@"1", @"2",@"3", nil]; [alert show]; [alert release]; waitingForResponse = YES; while (waitingForResponse == YES) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; ALog(@"running Loop1?"); [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; ALog(@"running Loop2?"); [pool drain]; } ALog(@"continues"); return orig__connect(sockfd, serv_addr, addrlen); ... </code></pre> <p>It should wait till the UIAlertViewDelegate method (in it's own class) sets waitingForResponse == NO.</p> <pre><code>extern BOOL waitingForResponse; @implementation FirewallRest - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { //NSLog(@"buttonIndex: %@", buttonIndex); if (buttonIndex == 0){ NSLog(@"0"); waitingForResponse = NO; } if (buttonIndex == 1){ NSLog(@"1"); waitingForResponse = NO; } if (buttonIndex == 2){ NSLog(@"2"); waitingForResponse = NO; } if (buttonIndex == 3){ NSLog(@"3"); waitingForResponse = NO; } } </code></pre> <p>but somehow that doesn't work :/</p> <p>does anyone have an idea? or a better way to do this? (I'm not very used to C and objC in one app ;))</p> <p>Thanks in advance for any help</p>
