问题 I'd like to be able to transfer files from a MacOS app to a connected iOS devices, so a related iOS app can open them - effectively replicating iTunes music functionality, but not for musc. Is this possible? I know you can set an iOS app to have file sharing enables so you can drop files into it with iTunes, but I'd prefer to do it in my own app. 回答1: This library came up in another question on SO recently: https://bitbucket.org/tristero/mobiledeviceaccess/ - I don't know anything about it

问题 I have created an NSTokenField in my xib. I'd like to display tokens with different colors inside that tokenField. Meaning: some tokens will be blue, the rest will be red (according to their content). Is that possible? The following code doesn't work for me. I hope someone can help me out: - (id)tokenField:(NSTokenField *)tokenField representedObjectForEditingString:(NSString *)editingString { id returnRepresentedObject = nil; NSTokenFieldCell *tf = [[NSTokenFieldCell alloc] init]; tf

问题 I'm a complete beginner to Swift, so this may be a silly question, but I can't figure out how this works... I have a view with a button inside which calls the following code: let window = NSWindow() window.center() window.title = "test" window.makeKeyAndOrderFront(self) When I click the button the window opens just for a moment and disappears a few milliseconds later. Can anyone help me with that? It seems I have a quite serious misunderstanding about views in Cocoa ;-) Thanks Tom 回答1: The

问题 1) Do I understand correctly that to draw using vertex arrays or VBOs I need for all my attributes to either call glBindAttribLocation before the shader program linkage or call glGetAttribLocation after the shader program was successfully linked and then use the bound/obtained index in the glVertexAttribPointer and glEnableVertexAttribArray calls? To be more specific: these three functions - glGetAttribLocation, glVertexAttribPointer and glEnableVertexAttribArray - they all have an input

问题 I'm currently using CoreAudio in macOS to determine if a specific audio input device is in use. I'm trying to find a little more information about what's going on with that device if it is in use, but struggling to find any information on how to do this. 1) Is it possible to find the application that is currently using a specific audio input device? 2) Is it possible to determine if an application is using an audio device (input or output) and has the device currently muted in that specific

问题 I have to use System.Windows.Forms for my C# course in school but I own a Macbook and Visual Studio says that it doesn't exist. I read that I could use WinForms if I installed Mono and then compile and run it from terminal using mcs hello.cs -pkg:dotnet . "hello.cs" is just a Hello World program using System.Windows.Forms... it compiles but when I do mono hello.exe it says: WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at

问题 I'm using a NSToolbar and I'm trying to change the color to a white instead of the default gray. How can I accomplish that? 回答1: Since the toolbar integrates into the window title bar, you need to draw both the title bar and the toolbar. Which basically means you need to take over drawing for the entire window. This requires "swizzling" which, while it works well, is not supported by Apple and therefore may get your app rejected from the app store. Basically you need to inject your own code
