1. .h文件實現?UIImagePickerControllerDelegate和?UINavigationControllerDelegate接口

?

2. 打開相機/相冊

具體函數中添加代碼：

UIImagePickerController *picker = [[UIImagePickerController alloc] init];picker.sourceType = UIImagePickerControllerSourceTypeCamera;picker.delegate = self;picker.allowsEditing = YES;[self presentViewController:picker animated:NO completion:nil];

其中，sourceType屬性代表打開?UIImagePickerController的樣式，

UIImagePickerControllerSourceTypePhotoLibrary 來自圖庫

UIImagePickerControllerSourceTypeCamera 來自相機

UIImagePickerControllerSourceTypeSavedPhotosAlbum 來自相冊

?

3. 實現代理方法

#pragma mark - UIImagePickerControllerDelegate - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info {[picker dismissViewControllerAnimated:NO completion:nil];NSString * type = [info objectForKey:UIImagePickerControllerMediaType];if ([type isEqualToString:@"public.image"]){UIImage * image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // image即為從相機/相冊獲取到的圖片} }- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {[picker dismissViewControllerAnimated:NO completion:nil]; }

?
