Color from Green to Red with Percentage

由 杀马特。学长 韩版系。学妹 提交于 2021-02-19 04:58:45
问题 i am trying to create a custom UIColor from Green to Red depends on a Percentage Value, but i have no idea how can i do something like that? Any ideas? 回答1: Something along these lines should work, if you just want a linear mix: func mixGreenAndRed(greenAmount: Float) -> UIColor { return UIColor(red: (1.0 - greenAmount), green: greenAmount, blue: 0.0, alpha: 1.0) } That one will blend through RGB (0.5, 0.5, 0), though—a kind of ugly orange—so you might want to do this instead, which will just

How to modify a cell of UITableView from another ViewController

由 烈酒焚心 提交于 2021-02-19 04:19:23
问题 In VC#1, I have a UITableView. When I tap on a cell, I am brought to VC#2 where information about that cell is displayed. I want to be able to press a button in VC#2 which changes the title of the cell it corresponds with in VC#1, but I am confused on how to do this? Should I create a variable in VC#2 to save the indexPath for the cell that was tapped, and then call a function in VC#1 from VC#2 that uses that indexPath to update the cell? If I did this, wouldn't VC#1 need to be static so I

didSelectRowAtIndexPath indexpath after filter UISearchController - Swift

由 只谈情不闲聊 提交于 2021-02-19 04:18:02
问题 I’m implementing a search bar with an UISearchController within a sectioned table. So far so good. The main issue is that when the the filtered results come along, it’s a whole new table with no sections and fewer rows. When selecting the row, I perform a segue to that position in the array, but the detailed view is expecting that exact row or index from the main array, which I can’t get from the filtered array of objects, which may be [0] [1] [2] in 300 elements. I guess I can compare the

How to pass non interpolated data OpenGL ES (GLSL)

由 我是研究僧i 提交于 2021-02-19 03:57:07
问题 I'm trying to pass simple FLOAT value from vertex to fragment shader. How can I pass it "as is" without interpolation? On desktop I could use flat varying to disable interpolation, is there something similar in openGL es or the only way is through texture? 回答1: GLSL ES does currently not support the flat keyword, so the only way is to use the same float value in all the triangle vertices. The same answer was given here: In opengl es 2, is there a way to prevent interpolation of varyings 回答2:

苹果App Store和iTunes曝出重大安全漏洞

由 ≯℡__Kan透↙ 提交于 2021-02-19 03:45:07
最近安全专家在苹果公司的App Store和iTunes发票系统中发现了一个重大漏洞。攻击者利用该漏洞可以劫持会话，恶意操控发票。Vulnerability Lab的安全研究员Benjamin Kunz Mejri本周公布其发现的这个漏洞。该重大的注入缺陷是应用程序端输入验证web漏洞。该安全研究员在公告中表示，通过这个漏洞远程攻击者可以向存在缺陷的内容功能和服务模块中注入恶意脚本代码。　 Mejri介绍表示攻击者可以利用该漏洞的方式是，更换恶意脚本代码，控制发票模块中的name值。如果该设备是在苹果店内购买的，后端就会利用name值将其编码添加操控条件，从而可以在发票发送给卖家之前生成发票。这样会导致的后果是在苹果发票中有应用程序端脚本代码执行。该漏洞的严重性评级为CVSS 5.8(通用脆弱性评级体系)。 此外网络攻击者还可以通过持续的操作环境与其他苹果应用商店用户的账号互动来控制这个漏洞，不管这些用户是发送方还是接收方都不会影响他们利用这个漏洞。该安全研究员表示，发票是提供给卖家和买家双方的，这会给买家、卖家或者苹果网页管理员/开发者带来很大的风险。 攻击者还能够利用这个漏洞来劫持用户会话，不断发起钓鱼攻击，创建链接到外部资源的持久重定向，操控被影响或相连的服务模块。 以下是概念验证视频，这名研究员还公开了利用这个安全漏洞的步骤。 Mejri
