[iOS Objective-C] 공유하기 - 메시지, 카카오톡, 페이스북, 트위터...

준비할것

- 카카오톡 API 홈페이지 들어가서 준비를 한다.
- 나머지 프레임 워크도 추가한다.

#import <MessageUI/MessageUI.h>
#import <KakaoOpenSDK/KakaoOpenSDK.h>
#import <Social/Social.h>
#import <Accounts/Accounts.h>

MFMessageComposeViewControllerDelegate 델리게이트를 등록한다. 메시지 전송 팝업을 컨트롤 할때 사용한다.

@interface ViewController () <MFMessageComposeViewControllerDelegate> {

}
@end

아래 코드는 실제 동작하는 코드

- (void) shareWithIndex:(NSInteger)buttonIndex text:(NSString *)text image:(UIImage *)image imageURLString:(NSString *)imageurl/*카톡 이미지 공유에서 쓰임*/ url:(NSURL *)url { if (buttonIndex==0) { // 문자 메세지 [self shareMessageWithText:text image:image url:url]; } else if (buttonIndex==1) { // 카카오톡 if ([KOAppCall canOpenKakaoTalkAppLink]) { // 카카오톡 공유 [self kakaoWithText:text image:image imageURLString:imageurl url:url]; } else { // 카카오톡 설치 [self openInstallKakaoAlert]; } } else if (buttonIndex==2) { // 페이스북 [self shareWithServiceType:SLServiceTypeFacebook Text:text image:image url:url]; } else if (buttonIndex==3) { // 트위터 [self shareWithServiceType:SLServiceTypeTwitter Text:text image:image url:url]; } } #pragma mark - 메시지 - (void) shareMessageWithText:(NSString *)text image:(UIImage *)image url:(NSURL *)url { if(![MFMessageComposeViewController canSendText]) { UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"메시지 보내기 기능을 지원하지 않습니다." message:@" " delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [warningAlert show]; return; } else { MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init]; if([MFMessageComposeViewController canSendText]) { controller.body = [NSString stringWithFormat:@"%@\n\n%@", text, url]; // controller.recipients = recipients; controller.messageComposeDelegate = self; NSData *data = UIImageJPEGRepresentation(image, 0); [controller addAttachmentData:data typeIdentifier:@"image/jpg" filename:@"thumbnail"]; [self presentViewController:controller animated:YES completion:nil]; } } } #pragma mark - 메시지 전송 delegate - (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result { [controller dismissViewControllerAnimated:YES completion:nil]; } #pragma mark - 카카오톡 - (void) kakaoWithText:(NSString *)text image:(UIImage *)image imageURLString:(NSString *)imageurl url:(NSURL *)url { // 카카오톡 KakaoTalkLinkAction *androidAppAction = [KakaoTalkLinkAction createAppAction:KakaoTalkLinkActionOSPlatformAndroid devicetype:KakaoTalkLinkActionDeviceTypePhone marketparam:nil execparam:@{@"kakaoFromData":[NSString stringWithFormat:@"{seq:\"%@\", type:\"%@\"}", self.dataInfo[@"contentsSeq"], self.dataInfo[@"contentsType"]]}]; KakaoTalkLinkAction *iphoneAppAction = [KakaoTalkLinkAction createAppAction:KakaoTalkLinkActionOSPlatformIOS devicetype:KakaoTalkLinkActionDeviceTypePhone marketparam:nil execparam:@{@"kakaoFromData":[NSString stringWithFormat:@"{seq:\"%@\", type:\"%@\"}", self.dataInfo[@"contentsSeq"], self.dataInfo[@"contentsType"]]}]; NSString *buttonTitle = @"앱으로 이동"; NSMutableArray *linkArray = [NSMutableArray array]; KakaoTalkLinkObject *button = [KakaoTalkLinkObject createAppButton:buttonTitle actions:@[androidAppAction, iphoneAppAction]]; [linkArray addObject:button]; /*[NSString stringWithFormat:@"%@ (%@)",[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleDisplayName"], LOC(@"msg_invite_kakao", @"경영전문대학원 MBA 모바일 주소록 앱")]*/ if (text) { KakaoTalkLinkObject *label; label = [KakaoTalkLinkObject createLabel:text]; [linkArray addObject:text]; } if (imageurl && image) { KakaoTalkLinkObject *kimage = [KakaoTalkLinkObject createImage:imageurl/*self.dataInfo[@"thumbnail1"]*/ width:image.size.width height:image.size.height]; [linkArray addObject:kimage]; } [KOAppCall openKakaoTalkAppLink:linkArray]; } - (void) openInstallKakaoAlert { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"카카오톡이 설치되어 있지 않습니다." message:@"카카오톡을 설치하겠습니까?"// @"Do you want to install the KakaoTalk?" delegate:self cancelButtonTitle:@"취소" otherButtonTitles:@"확인", nil]; alert.tag = 141; [alert show]; } #pragma mark - Alert View Delegate - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (alertView.tag==141) { if (buttonIndex==[alertView cancelButtonIndex]) { // cancel } else { // 카카오톡 링크로 이동 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/kr/app/id362057947"]]; } } } #pragma mark - 페이스북 트위터 - (void) shareWithServiceType:(NSString *)serviceType Text:(NSString *)text image:(UIImage *)image url:(NSURL *)url { if ([SLComposeViewController isAvailableForServiceType:serviceType]) { SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:serviceType]; if (text) [mySLComposerSheet setInitialText:text]; if (image) [mySLComposerSheet addImage:image]; if (url) [mySLComposerSheet addURL:url]; [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) { switch (result) { case SLComposeViewControllerResultCancelled: NSLog(@"Post Canceled"); break; case SLComposeViewControllerResultDone: NSLog(@"Post Sucessful"); break; default: break; } }]; [self presentViewController:mySLComposerSheet animated:YES completion:nil]; } else { [[[UIAlertView alloc] initWithTitle:@"실패" message:@" " delegate:nil cancelButtonTitle:@"확인" otherButtonTitles:nil] show]; } }

페이스북, 트윗 등등 다른 기본 소셜 공유기능을 사용하려면

SOCIAL_EXTERN NSString *const SLServiceTypeTwitter NS_AVAILABLE(10_8, 6_0);
SOCIAL_EXTERN NSString *const SLServiceTypeFacebook NS_AVAILABLE(10_8, 6_0);
SOCIAL_EXTERN NSString *const SLServiceTypeSinaWeibo NS_AVAILABLE(10_8, 6_0);
SOCIAL_EXTERN NSString *const SLServiceTypeTencentWeibo NS_AVAILABLE(10_9, 7_0);
SOCIAL_EXTERN NSString *const SLServiceTypeLinkedIn NS_AVAILABLE(10_9, NA);

상수 스트링을 사용하면 된다. 이 포스팅에서는 SLServiceTypeFacebook, SLServiceTypeTwitter 만 사용했다.
