如何確定圖像是從庫中還是從相機中獲取的

Question

我想通過if語句檢查是否從相機膠卷中拾取圖像或由內置相機拍攝圖像。 如何通過if語句執行此操作？ 謝謝你的幫助！

碼：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{

if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {

    toolbar.hidden = NO;
}

if (picker.sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {

    toolbar.hidden = NO;
}

if (picker.sourceType == UIImagePickerControllerSourceTypeSavedPhotosAlbum) {

    toolbar.hidden = NO;
}

else{

    toolbar.hidden = YES;
}

imgView.image = [info objectForKey:@"UIImagePickerControllerEditedImage"];

[self dismissViewControllerAnimated:YES completion:nil];
}

只需檢查sourceType ：

if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
    //image taken with camera
}
else{
    //image taken from camera roll
}

在imagePickerController:didFinishPickingMediaWithInfo:方法中執行此操作。
