问题 When I'm using a UIActivityViewController , after the user chooses an activity (such as Mail or Message), I can not change the text color for the status bar nor the text/tint color of the Cancel and Send navigation bar buttons. For the bar buttons, in the AppDelegate I've tried using: [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]]; And nothing happens. However I am able to set the navigation bar title with this: [[UINavigationBar appearance] setTitleTextAttributes:

问题 I've already looked at related questions here and here, and I have implemented the suggested answers to no avail. I have a UIBarButtonItem on a UIToolbar, with Connection for Send Action to btnTBAction_touch: In the ViewController's class header I have: @property (nonatomic, strong) UIActivityViewController *activityViewController; The related method in the class implementation: - (IBAction)btnTBAction_touch:(id)sender { NSString *string = @"Some string"; NSURL *url = [[NSURL alloc]

问题 When a UIActivityViewController is called on the iPhone in this app, it works perfectly, but when called on a iPad, the app crashes. Below is the code I used: func shareButtonPress() { //when the share button is pressed, default share phrase is added, cropped image of highscore is added var sharingItems = [AnyObject]() var shareButtonHighscore = NSUserDefaults.standardUserDefaults().objectForKey("highscore") as Int! sharingItems.append("Just hit \(shareButtonHighscore)! Beat it! #Swath")

My app is in Swift but the 1Password is in Objective-C. Here's the code I'm using for the ActivityViewController: @IBAction func _shareButton(sender: UIButton) { var shareContent = _searchBar.text if let myWebsite = NSURL(string: "\(

问题 I am currently doing some updates for an iOS application. For the update I am going to take advantage of iOS6 capabilities. I am using a UIActivityViewController to get this done as well as some custom UIActivity activities. The main issue I am having is that there is no "Cancel" or "Close" button. The only way you can exit out of the activity view is if you either post something to a social network, or act like you are going to and then cancel. NSArray* dataToShare = [[NSArray alloc]

问题 Following up from this question, how would I go about using UIActivityViewController to specify the file type of a file I am sharing over airdrop? 回答1: Worked it out: let myFileManager = FileManager.default var activityArray = [NSURL]() activityArray.removeAll() for (i, data) in dataToShare.enumerated() { let docsurl = try! myFileManager.url(for:.documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) let myurl = docsurl.appendingPathComponent("shareData\(i).gymProf") var
