随声附和 提交于 2021-02-10 13:27:49
问题 I have a situation where I have to reposition the map box compass view to a different location. The compassView is now rotating when I rotate the map taking some other point as its(compassView) axis and gives me a weird outcome. Screenshot is attached, the black mapBox default compass icon is rotating, refer the screenshots. Is this a MapBox sdk bug? if so, are there any work around? And tweaks? I am confused. Expert advices needed. Thanks in advance. 回答1: Hey I found another method where I

https://zhuanlan.zhihu.com/p/104210726 武汉新型肺炎让这个春节变得痛心和揪心,也打乱了不少人的计划。我老家就在湖北,虽然本人并没有回老家,但是有不少亲朋好友在那边。此外,因为项目合作关系,我过去两年也差不多有一半的时间呆在武汉。 但是,作为一个普通人,既非政府官员又非医护人员,或是可以直接提供贡献的相关工作人员,如果没有被感染,那么不管是不是在武汉,春节期间唯一能做的就是,老老实实做个宅男宅女,为2020年重新做一下规划,顺便给自己充充电。 《银河系漫游指南》中的一句话曾经风行整个宇宙,那就是"Don't panic",”不要恐慌“。 另外,在我们这个星球上也有一个勇敢的人反复说过,我们无论面对任何困难,都不要害怕,微笑着面对它,奥利给! 欢迎继续我们的学习。 更改欢迎的文字内容 虽然“Hello World”足够经典,但是似乎有点过于无趣。接下来我们可以尝试着更改一下要显示的文本内容。 1.在Canvas中,点击”Hello World”。 当你选中这段文本时,会看到在Canvas视图和代码编辑器中相应的文本都会被高亮。 在Canvas视图中: 在代码编辑器中: 之所以”Hello World”在两个地方同时被高亮,是因为它们代表着同一个事物的两种观察方式。 代码编辑器中使用代码的形式显示了用户界面的内容

编译FFmpeg

编译FFmpeg,这是一个古老的话题,但是小程还是介绍一遍,就当是记录。 小程之前介绍怎么给视频添加水印时,就已经提到FFmpeg的编译,因为需要在编译时指定滤镜的功能,读者可以关注“广州小程”微信公众号并查阅这篇文章(音视频->FFmpeg应用)。 但是,在手机盛行的时代,读者可能更需要的是能在iOS或Android平台上运行的FFmpeg,而对于命令行的ffmpeg,读者可以在个人电脑上面使用(因为它简洁易操作),也可以在服务程序中使用(安装FFmpeg后直接调用ffmpeg命令),比如小程经常在自己的mac机上使用ffmpeg命令。 本文介绍如何编译出iOS或Android平台使用的FFmpeg链接库。 正如编译macos平台使用的FFmpeg一样,编译iOS或Android平台使用的FFmpeg,主线也是先configure再make,只不过,有更多的细节需要考虑。 小程使用的是macos系统。 (1)编译环境准备 (a)pkg-config FFmpeg在编译时经常使用到第三方库(比如x264、rtmp等),编译器在查找这些第三方库的头文件与库文件时,需要使用到程序pkg-config。 pkg-conifig给编译器提供路径与链接选项。第三方库在make install时会生成pc后缀的文件并拷贝到系统目录,而pkg-config就是从这个pc文件读取出路径信息。

iOS 13.4 Crashes app with vague message: precondition failure: type check failed: 101, expected Text, got _HiddenModifier

问题 Sorry to be vague in the description here, but this has caused my app to be completely DOA when a user attempts to use my search feature. This did not happen before iOS 13.4 and the error message is not helpful at all. Cant find any info. Has anyone run into this? where could it be? The app crashes at the point where in my SwiftUI file, I populate the view using a ForEach from an array, which is an observable object: ForEach(self.listArray.searchDataArray, id: \.self) { fetchedData in Ill

问题 I am using phone verification in my flutter app. My goal is to have the following flow: 1. user enters phone number 2. user is sent verification code 3. user enters code and is signed in. On android, that is the flow I get. On ios, however, it goes 1. user enters phone number 2. reCAPCHA page opens to make sure I'm not a robot 3. user is sent verification code 4. user enters code and is signed in (this happens on ios emulator). I want to get rid of the reCAPCHA page. Some people recommended

问题 I’m trying to include openmp to my Xcode C++ project. I have changed my compiler in Xcode to LLVM GCC 4.2, added ”-fopenmp” as a CFlag and enabled OpenMP support in xcode as well. But it still says ”‘omp.h’ file not found” and i am unable to build the project. Does anyone know what could be wrong and how to fix this? 回答1: I have had the same problem. Try going to the project navigator using the panel at the left side. Select your project (the one with the blue icon), and a different main

Cocoa Key Equivalent in Menu is not working

孤街浪徒 提交于 2021-02-10 05:51:53
问题 I have created a NSStatusItem and I have assigned two key equivalents within interface builder (Xcode 4.0). These are for the preference menu cmd-, and the quit option cmd-q. Both of these will work when the Menu is highlighted/open but will not work otherwise even if the application is the foremost. Any ideas on why this is happening or how I can change this? 回答1: The operating system passes key events that it doesn't handle to the front application, which compares them to any key
