iOS share extension dismiss keyboard

阅读更多关于 iOS share extension dismiss keyboard

I'm implementing a share extension for my app, so far everything is going good except I can't seem to dismiss the keyboard that automatically opens using the default layout/storyboard. I'm keeping the default design/layout (SLComposeServiceViewController) which includes the preview image and UITextview, the UITextview automatically gets in focus which opens the keyboard. Normally this is fine, but if you're not logged in my app I display an UIAlertController saying you need to login to share. The problem is the keyboard opens at the same time as the alert. I've tried [self.view endEditing:YES]

Inside Activation rules there is the rule to allow text, but the extension is not available when I select the text. 回答1: You need to turn on NSExtensionActivationSupportsWebURLWithMaxCount to make extension available in Safari. When you create a non-UI action extension target from the template, an Action.js file is automatically created. Edit the file to send back the selected text using document.getSelection().toString() 来源：

I'm trying to create an iOS game and I have it so that when the item is touched and moved it is dragged. When it is dragged the mouse is snapped to the center of the sprite.

Here are the functions dealing with touch input override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) { var papers = 0 for touch in (touches as!

问题 I'm currently developing an iOS application that integrates Facebook and I'm having a bit of a problem while investigating this with Swift (with ObjC I have no problems).

The issue is the following: When the user clicks on the location in the MapView it goes to an empty collection view. If the user pulls to refresh, the spinner is active but the images do not load. However, if the user goes back to the MapView and then clicks on the location again, the images are loaded in the collection view. Of course we are trying to get the images loaded when the user first goes to the

Determine if a copy to UIPasteboard was successful or not

阅读更多关于 Determine if a copy to UIPasteboard was successful or not

问题 I'm programmatically copying an image to the UIPasteboard, and I want to determine if the copy was successful or not. Specifically, I'm creating an custom keyboard on iOS 8, where some of the keys will copy an image to the pasteboard for the user to paste in a textfield. UIPasteboard *pasteBoard = [UIPasteboard generalPasteboard]; [pasteBoard setImage:[UIImage imageNamed:anImage]]; To do this, the user must allow "Full Access" on the keyboard. So I either have to have a way to determine if
