1. Project 생성
Single View Application
2. Lib 추가
MobileCoreServices.framework
3. UIViewController(기본적으로 생성되어 있던) UI 구성
사진을 표시할 UIImageView *imageView
카메라로 연결할 버튼 : UIButton *cameraBtn
앨범으로 연결할 버튼 : UIButton *albumBtn
4. 델리게이트
UIImagePickerControllerDelegate
UINavigationControllerDelegate
기본 UIViewController에 추가
.h >
#import <MobileCoreServices/MobileCoreServices.h>
@interface XXXXXXViewController : UIViewController
<UIImagePickerControllerDelegate, UINavigationControllerDelegate>
@property (assign, nonatomic) BOOL newMedia;
@property (strong, nonatomic) IBOutlet UIImageView *imageView <- GUI의 UIImageVIew와 연결
.m >
@synthesize imageView;
@synthesize newMedia;
5. 버튼의 이벤트 핸들러
이벤트 핸들러를 작성하고,
GUI의 버튼과 이벤트 핸들러를 연결
.m에서
// 카메라 버튼을 눌렀을 때의 이벤트 핸들러
- (IBAction)useCamera:(id)sender {
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker animated:YES];
newMedia = YES;
}
}
//Album버튼을 눌렀을 때의 이벤트 핸들러
- (IBAction)useCameraRoll:(id)sender {
if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeSavedPhotosAlbum]){
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imagePicker.allowsEditing = NO;
[self presentModalViewController:imagePicker animated:YES];
newMedia = NO;
}
}
.m에서
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:YES];
if([mediaType isEqualToString:(NSString *)kUTTypeImage]){
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
if (newMedia) UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:finishedSavingWithError:contextInfo:), nil);
}else if([mediaType isEqualToString:kUTTypeMovie]){
// for movie
}
}
- (void) image:(UIImage *) image finishedSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
if(error){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Save failed" message:@"Failed to save image" delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker{
[self dismissModalViewControllerAnimated:YES];
}
