Cant access NString after callback in [NSURLConnection sendSynchronousRequest]
- by John ClearZ
Hi I am trying to get a cookie from a site which I can do no problem. The problem arises when I try and save the cookie to a NSString in a holder class or anywhere else for that matter and try and access it outside the delegate method where it is first created.
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
int i;
NSString* c;
NSArray* all = [NSHTTPCookie cookiesWithResponseHeaderFields:[response allHeaderFields] forURL:[NSURL URLWithString:@"http://johncleary.net"]];
//NSLog(@"RESPONSE HEADERS: \n%@", [response allHeaderFields]);
for (i=0;i<[all count];i++)
{
NSHTTPCookie* cc = [all objectAtIndex: i];
c = [NSString stringWithFormat: @"%@=%@", [cc name], [cc value]];
[Cookie setCookie: c];
NSLog([Cookie cookie]) // Prints the cookie fine.
}
[receivedData setLength:0];
}
I can see and print the cookie when I am in the method but I cant when trying to access it form anywhere else even though it gets stored in the holder class
@interface Cookie : NSObject
{
NSString* cookie;
}
+ (NSString*) cookie;
+ (void) setCookie: (NSString*) cookieValue;
@end
int main (void)
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
JCLogin* login;
login = [JCLogin new];
[login DoLogin];
NSLog([Cookie cookie]); // Crashes the program
[pool drain];
return 0;
}
