如何在ios中实现拍照或从图库选项中选择[重复]

Question

任何人都可以帮我实现一个功能 --> 当在应用中选择相机选项时，拍照或从图库选项中选择。

Answer 1

// 用于相机拍照

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [self presentViewController:picker animated:YES completion:nil];

// 用于从图库中选择图片

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:picker animated:YES completion:nil];

// 用于输出图像

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

    // output image
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.profileImageView.image = chosenImage;
    [picker dismissViewControllerAnimated:YES completion:nil];

}

别忘了添加 UIImagePickerControllerDelegate 和 UINavigationControllerDelegate。
