问题 How do I add Tags to a jpeg picture on UWP (universal Windows Platform) / Windows Phone 10. WindowsBase and PresentationCore not available. 回答1: Here is an example about how to write the Artist exif tag to a jpeg image in Windows Runtime.

问题 I wrote an iPhone app. Then, I changed the interface a fair bit, added higher res images, and made an iPad version of it. In a perfect world, I would like for anyone who buys the iPad version to get the iPhone version for free (though not conversely). Since Apple doesn't seem to have a way to do that (right??), my next favorite solution is to make the iPad version include the iPhone version somehow. I know that I could just convert the iPad version to "universal", but since the face of the

问题 I'm making a universal app based on the Utility App template. I've selected a universal app and the MainView.xib and MainView~iPad.xib work properly on both device types. On the iPad2, when I switch to the FlipsideView, it loads FlipsideView.xib even though there is a perfectly good FlipsideView~iPad.xib file in the project. The default xib is normal (iPhone) sized and displaying in the lower left hand corner of the iPad. I did have to create the FlipsideView~iPad xib manually. I believe I

问题 while porting our latest iPhone App to an universal app, I decided to use a iPad's SplitView Controller inside of a TabBarController. The SplitViewController is managed by AppDelegate for every Tab. All works fine, but my problem is that my MasterView (on the left of the SplitView) includes 4 Category-Buttons to change the TableViews Data. If I click one of the buttons, the TableView needs to Refresh/ReloadData, to Display the new Content of the selected category. I created a function to do

问题 I am trying to create a universal binary that supports multitasking on the iPhone 4 and can still run on the iPad. I know how to avoid compile errors for different versions of the iPhone IOS by checking if a class exists by using NSClassFromString and "respondToSelector", but is there a way to check for the existence of constants like UIBackgroundTaskInvalid? I of course can use #IFDEF, but I want to avoid this. 回答1: You do it as follows: if (NULL != &UIBackgroundTaskInvalid) { //do

问题 I am absolutely new to programming. I'm trying to create a very simple app with three TextBoxes and one final TextBlock. I want to save the input from these three TextBoxes locally so I can read and display it in a TextBlock on the bottom of the page in one string. I have read that the StreamWriter class is what I should be using. I just don't know where to start... There's basically not a lot of code so far really public sealed partial class MainPage : Page { public MainPage() { this

问题 Is there a way for me to create an Applescript as a run only application that would work on 10.5 and above? I am running Lion. Whenever I save my script as a run only application it does not work with 10.5 and gives me a "does not work with this architecture" error. The weird thing is that I saved it once and successfully launched it on the 10.5 machine but when I went to edit it and re-save it did not work anymore. Thx 回答1: You can't and Apple's documentation isn't clear. My experience,

问题 I'm trying to migrate angular 1.4 to angular4 universal for SEO purposes. Everything works well.
