Ios 将ImagePicker从“更改为”；使用照片“；至；保存照片

我的应用程序中有一个部件，用户可以在其中快速拍照并将其保存到相机卷中。我唯一想做的是，在拍摄完照片后，它会用方形裁剪器（我猜就是这样）出现在屏幕上，然后在底部写上“重新拍摄”和“使用照片”。我想让那个使用照片的人说“保存照片”（不管怎么说，它就是这么做的）。有什么办法可以这样做吗？ 这是我的密码

- (IBAction)takePhoto:(UIButton *)sender {

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

[self presentViewController:picker animated:YES completion:NULL];
}

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

UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
self.imageView.image = chosenImage;
UIImageWriteToSavedPhotosAlbum(chosenImage, nil, nil, nil);
[picker dismissViewControllerAnimated:YES completion:NULL];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

[picker dismissViewControllerAnimated:YES completion:NULL];
}

您可以将“取消”按钮更改为您想要的任何标题：

添加UINavigationControllerDelegate委托给您的viewController，您将单击按钮并显示相机

在viewController中添加以下代码：

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {

[[UIApplication sharedApplication] setStatusBarHidden:YES];
[self changeCancelToAnythingUWantOf:viewController andReplacementString:@"Your Replacement String"];

}

你可以通过递归的方式找到这个

func buttonWithTitle(forView view: UIView, title: String) -> UIButton? {
    guard view.subviews.count > 0 else { return nil }
    var needButton: UIButton? = nil
    for subview in view.subviews {
        if subview is UIButton {
            let button = subview as! UIButton
            if button.titleLabel?.text == title {
                return button
            }
        }

        needButton = buttonWithTitle(forView: subview, title: title)
        if needButton != nil { return needButton }
    }

    return needButton
}

第一个swizzling Bundle

private func swizzle（ubundle:bundle.Type）{
[（#选择器（bundle.localizedString（forKey:value:table:）），
#选择器（bundle.rd_localizedString（forKey:value:table:））]
.forEach{原件，插入
guard let originalMethod=class_getInstanceMethod（捆绑，原始），
让swizzledMethod=class_getInstanceMethod（bundle，swizzled）else{return}
设didAddMethod=class\u addMethod(
捆
起初的
方法_getImplementation（swizzledMethod），
方法\u getTypeEncoding（swizzledMethod）
)
if-didAddMethod{
类替换方法(
捆
嗖嗖地一声，
方法_getImplementation（原始方法），
方法\获取类型编码（原始方法）
)
}否则{
方法交换实施（原始方法、swizzledMethod）
}
}
}
私有变量hasSwizzled=false
扩展包{
最终公共类函数
doBadSwizzleStuff（）{
守卫！哈斯威兹勒索其他人{返回}
hasSwizzled=true
swizzle（自我）
}
@objc内部函数rd_本地化字符串（forKey:String，value:String？，table:String？->String{
设bundle=bundle.main
return bundle.rd_localizedString（forKey:forKey，value:value，table:table）
}
}

第二步为UIImagePickerController创建本地化字符串 下面是我看到的带有键的文件内容（带有标准英文值），它们可以自我解释

卡默劳伊 PhotoLibraryServices.String PhotoLibrary.strings PhotosUI.strings 第三，实现本地化类

不，无法更改按钮的标题。是否有解决方法？还有，有没有办法摆脱方形作物之类的东西？只拍摄完整照片？可能使用您自己的相机视图覆盖和“重拍/保存”屏幕，而不是启用

属性。这不适用于更改“使用照片”按钮文本，因为它不在这些视图中。有什么想法吗？谢谢所以，不要使用默认的摄像头控件，请下载示例代码：（苹果的示例代码可能有你想要的）

func buttonWithTitle(forView view: UIView, title: String) -> UIButton? {
    guard view.subviews.count > 0 else { return nil }
    var needButton: UIButton? = nil
    for subview in view.subviews {
        if subview is UIButton {
            let button = subview as! UIButton
            if button.titleLabel?.text == title {
                return button
            }
        }

        needButton = buttonWithTitle(forView: subview, title: title)
        if needButton != nil { return needButton }
    }

    return needButton
}
