我正在使用更新版本的 swift。我猜在ios9中不支持alertview。那么我该如何实现这个要求从图库或相机胶卷中拍照的警报呢?
最佳答案
UIAlertView
仍然可以使用,但从 iOS 8 开始已弃用。呈现警报的首选方式是使用具有 UIAlertControllerStyleAlert
样式的 UIAlertController
.
let alertController = UIAlertController(title: "Alert title", message: "Alert Message", preferredStyle: .Alert)
let cameraRollAction = UIAlertAction(title: "Camera Roll", style: .Default) { (action) in
self.imagePicker.delegate = self
self.imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum;
self.imagePicker.allowsEditing = false
self.presentViewController(self.imagePicker, animated: true, completion: nil)
}
alertController.addAction(cameraRollAction)
let takePictureAction = UIAlertAction(title: "Take a picture", style: .Default) { (action) in
self.imagePicker.allowsEditing = false
self.imagePicker.sourceType = UIImagePickerControllerSourceType.Camera
self.imagePicker.cameraCaptureMode = .Photo
self.imagePicker.modalPresentationStyle = .FullScreen
self.presentViewController(self.imagePicker,
animated: true,
completion: nil)
}
alertController.addAction(takePictureAction)
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
}
alertController.addAction(cancelAction)
self.presentViewController(alertController, animated: true) {
}
