问题 Here is a screenshot of a UIAlertController . I was just playing around custom fonts and textfield properties but I was unable to accomplish the following: clear background of the UITextField no ugly border (black box) as shown below As I dived more into the code and iOS runtime headers, I was able to modify border and background color but the above issue still remains as those properties belong to a container UITextView . Changing background to clearColor doesn't help. Has anybody ever

问题 I'm totally new to swift (and iOS programming at all), but I started messing around with it (it wasn't a good idea when everything is still beta version :D). So I tried to figure it out by myself, but still nothing. Even tried to add subview containing picker without any success. So can any one help me? 回答1: Well this is my final code which worked for me. It is a mix by a few ideas. The main reasons that I will accept my answer is that my code is in Swift, my code uses UIAlertController, my

问题 Due to strange behavior of UIActionSheet in iOS 8, I have implemented UIAlertController with UIAction as buttons in it. I would like to change the entire background of the UIAlertController. But I can't find any ways to do it. Tried even with, actionController.view.backgroundColor = [UIColor blackColor]; But didn't help me out. Any inputs on this regard will be appreciable. Thanks in advance. 回答1: You have to step some views deeper: let subview = actionController.view.subviews.first! as

问题 I have this code: var zdjecieGlowne: UIImage? = nil let alert = UIAlertController(title:"MyTitle", message: "My Message Box ", preferredStyle: UIAlertControllerStyle.alert) let saveAction = UIAlertAction(title: "MyTitle", style: .default, handler: nil) //saveAction.setValue(UIImage(named: "logo")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal), forKey: "image") saveAction.setValue(zdjecieGlowne, forKey: "image") dump(zdjecieGlowne) alert.addAction(saveAction) alert.addAction

One of the options in the Alert Controller should take them directly to location services (for the OS, not the app). Right now, I've gotten as far as being able to send the user to permissions for my specific app, but not for the overall OS location settings. Is there a way to send the user directly to the OS Location settings from the UIAlertController? Here is the current code (located

问题 I would like to present a UIAlertController with 2 buttons. One button should close the alert and the second should perform an action but remain the alert on screen. Is there some configuration that can be done to action that it won't close the alert?
