问题 I completed this tutorial by Simon Gladman (@flexmonkey) to capture images from AVFoundation and apply a filter to the output. However, I'm struggling to find a way to replace the blur filter with my own compute shader. In other words, I need to concatenate my custom shader after the YCbCrColorConversion filter mentioned there. let commandBuffer = commandQueue.makeCommandBuffer() let commandEncoder = commandBuffer.makeComputeCommandEncoder() // pipelineState has compiled YCbCrColorConversion

问题 I'm having a problem with assets and Xcode 9 beta running on devices with iOS 10. It doesn't upload any image from assets, so on the phone I can't see any asset!

问题 Using an iPad with iOS 10 installed, I entered window.outerWidth in the browser console and got a value of 0 . OTOH, window.innerWidth correctly produced 1024 (landscape mode). In iOS 9, window.outerWidth correctly produced 1024 , so is this just a bug in the iOS 10 beta or is there a subtlety to this property that I'm missing? 回答1: The issue is more than just the iOS 10 Beta, but I doubt it is a priority for Apple Devs to fix as iOS devices don't really have an external frame on the sides of

问题 I have an ipad application that I would like to run on iPad pro, but when I run it, it only occupies one corner of the screen like so: Now, another stackoverflow question asked the same question and the response was to remove the launch screen file and not to give the OS any hardcoded information about the device size it's going to run on.

问题 Why does Xcode 8 (iOS 10) print [LogMessageLogging] <private> in the console, when I call the map view? Can any one give some suggestions? 回答1: Privacy The unified logging system considers dynamic strings and complex dynamic objects to be private , and does not collect them automatically. To ensure the privacy of users, it is recommended that log messages consist strictly of static strings and numbers . In situations where it is necessary to capture a dynamic string, you may explicitly
