過去2日間これを試してきましたが、答えがわかりません。私はすべてを検索しましたが、答えは見つかりませんでした。
質問は、アプリでカメラを起動するボタンがあることです (写真のみを撮るため)。カメラは開きますが、写真を撮って右下に表示されている「USE」をクリックするとクラッシュします。また、カメラが開くと、写真を撮る前に「キャンセル」をクリックすると再びクラッシュします。
ブレークポイントを使用してみましたが、「USE」ボタンをクリックすると、この行でクラッシュすることがわかりました
[picker dismissViewControllerAnimated:YES completion:Nil]
iPad（iOS6）でテストしています。
ボタンコードは次のとおりです。
-(IBAction)getAlbum:(id)sender {
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
NSArray *media = [UIImagePickerController
availableMediaTypesForSourceType: UIImagePickerControllerSourceTypeCamera];
if ([media containsObject:(NSString*)kUTTypeImage] == YES) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
//picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
[picker setMediaTypes:[NSArray arrayWithObject:(NSString *)kUTTypeImage]];
picker.delegate = self;
//[self presentModalViewController:picker animated:YES]; //Since [Modal](http://stackoverflow.com/questions/12445190/dismissmodalviewcontrolleranimated-deprecated) has been removed
[self presentViewController:picker animated:YES completion:Nil];
//[picker release];
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unsupported!"
message:@"Camera does not support photo capturing."
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Unavailable!"
message:@"This device does not have a camera."
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
imagePickerController メソッドはこちら:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSLog(@"Media Info: %@", info);
NSString *mediaType = [info valueForKey:UIImagePickerControllerMediaType];
if([mediaType isEqualToString:(NSString*)kUTTypeImage]) {
UIImage *photoTaken = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
//Save Photo to library only if it wasnt already saved i.e. its just been taken
if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
UIImageWriteToSavedPhotosAlbum(photoTaken, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
}
selectedLogoImg.image=photoTaken; //selectedLogoImg is the imageView
[self.clipartItemView addSubview:selectedLogoImg]; // To detect touch and move it I place it as a subview of self.clipartItemView
}
//[picker dismissModalViewControllerAnimated:YES];
[picker dismissViewControllerAnimated:YES completion:Nil]
//[picker release];
//[picker dismissViewControllerAnimated:YES completion:^{
// NSLog(@"Dismiss completed");
//}];
}
ここにdidFinishSavingWithErrorコード：
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
UIAlertView *alert;
//NSLog(@"Image:%@", image);
if (error) {
alert = [[UIAlertView alloc] initWithTitle:@"Error!"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
}
imagePickerControllerDidCancel コードは次のとおりです。
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
//[picker dismissModalViewControllerAnimated:YES];
/*[picker dismissViewControllerAnimated:YES completion:^{
[self.view sendSubviewToBack:cardGalleryView];
}];*/
[picker dismissViewControllerAnimated:YES completion:Nil];
}
