UIAlertAction按钮文本左对齐

问题描述：

我想将 UIAlertAction 文本对齐方式与左对齐，并添加图标，如图所示。我花了很多时间在谷歌上获得解决方案，但没有找到正确的答案。警报标题的每个正文帖子都不是警报操作标题。

I want to align UIAlertAction text alignment to Left and add the icon as in image shown. I spent lot of time on google to get the solution but not found the right answer. Every body post for the alert title not for the alert action title.

请建议我使用 swift 的正确方法。

Please suggest me the right way for swift.

谢谢!!

你可以用下面的例子来做到这一点码。简单明了。

You can do that with bellow example code. Easy and Simple.

Swift 4

let actionSheetAlertController: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
actionSheetAlertController.addAction(cancelActionButton)


let documentsActionButton = UIAlertAction(title: "Documents", style: .default, handler: nil)
actionSheetAlertController.addAction(documentsActionButton)
documentsActionButton.setValue(#imageLiteral(resourceName: "doccument"), forKey: "image")
documentsActionButton.setValue(kCAAlignmentLeft, forKey: "titleTextAlignment")

let cameraActionButton = UIAlertAction(title: "Camera", style: .default, handler: nil)
actionSheetAlertController.addAction(cameraActionButton)
cameraActionButton.setValue(#imageLiteral(resourceName: "camera"), forKey: "image")
cameraActionButton.setValue(kCAAlignmentLeft, forKey: "titleTextAlignment")

let galleryActionButton = UIAlertAction(title: "Gallery", style: .default, handler: nil)
actionSheetAlertController.addAction(galleryActionButton)
galleryActionButton.setValue(#imageLiteral(resourceName: "gallery"), forKey: "image")
galleryActionButton.setValue(kCAAlignmentLeft, forKey: "titleTextAlignment")

actionSheetAlertController.view.tintColor = kTHEME_COLOR
self.present(actionSheetAlertController, animated: true, completion: nil)
