iphone http Request
1. Sync
NSURL *url = [NSURL URLWithString:kURLPath];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLResponse *response;
NSError *error = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:&response error:&error];
if(data == nil) { NSLog(@”%@”, [error description]);
}
2. ASync
NSURL *url = [NSURL URLWithString:kURLString];
NSURLRequest *request = [NSURLRequest requestWithURL:url]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
NSUrlConnectionDelegate 사용
NSURLConnectionDelegate Header 응답
Body 전송
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)aResponse { response = [aResponse retain];
if ([response expectedContentLength] < 0) { [connection cancel];
}
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)aData {
// 다운로드한 데이터를 추가 [receiveData appendData:aData];
}
NSURLConnectionDelegate
전송 완료
오류 처리
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
UIImage *image = [UIImage imageWithData:receiveData] [self.imageView setImage:image];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Connection Error"
[alert show]; [alert release];
}
message:[error description] delegate:self
cancelButtonTitle:@"Close" otherButtonTitles:nil];
ASIHTTPRequest
HTTP 요청과 응답 관련 라이브러리 간편한 사용성 보안 및 인증 지원 Queue를 활용한 다중 다운로드 지원

메모리 관리 기법 3가지
1. retain realse
2. pool 을 사용
main.m 을 사용..
3. gabage collection
2. pool 을 사용
main.m 을 사용..
NSAutoRealsePool pool = ... alloc
....
[pool drain]
중첩해서 사용도 가능하다..
3. gabage collection
iphone map 이용하기
1. Map SDK 를 추가하고
2. xlb 의 map view 에 delegate 를 추가한다.
