Building for iOS Simulator, but the linked framework '****.framework' was built for iOS

由 可紊 提交于 2020-12-21 06:21:12
问题 I cannot run my app on simulators anymore. Online suggested that I edit my project.pbxproj, but that does not appear to work. How do I reclaim the ability to run my project on my simulator (and remain able to do so on a device)? I am working on another project that uses many of the same frameworks, but it runs on a simulator. What would cause a similar framework to work in one project but not in another? 回答1: Xcode 12.3 In my case I solved this problem by simply setting Validate Workspace to

How to add salt to AES Encryption in iOS and decrypting it using objective c

问题 I have appended the IV to the AES Encryption/decryption code by using objective c in iOS and able to decrypt and encrypt the same. Right now I am trying to add the salt to the AES Encryption but unfortunately its not working for me. Here is the code: I have also edited with Android salt generation code for just to check whether my salt generation is valid or not in iOS Encryption code: + (NSData*)encryptData:(NSData*)data key:(NSData*)key error:(NSError **)error; { NSData *salt = [self

Xcode快捷键

其实就是设置里面的快捷键变成了文字版，费了我不少工夫。。。希望对大家有帮助 可能有些新手刚用mac，不知与windows键对应，现在说明一下，command相当于ms键盘的win键，option相当于alt，键值一样，系统偏好设置里面可以更改。 xcode相关： 关于xcode 可设 偏好设置 command+, 清空缓存 可设 隐藏xcode command+h 隐藏其它 command+option+h 显示全部 可设 退出xcode command+q 文件相关： 新建项目 command+shift+n 新建文件 command+n 新建空文件 command+control+n 打开 command+o 在新窗口中打开 command+option+o 快速打开 command+shift+d / command+shift+alt+d (不知区别是什么) 清空最近打开文件 可设 清空最近打开项目 可设 Get Info command+i 显示检查器？ command+option+i (效果和Get Info一样，不知区别) 关闭窗口 command+w 关闭所有窗口 command+option+w 关闭当前项目 command+control+w 关闭当前文件 command+shift+w 保存文件 command+s 保存所有文件 command+option

30 分钟集成融云 IM 即时通讯

最近公司要做一个社交 app，对于时间就是金钱的当今社会，招聘大量人才去搭建通讯系统肯定是不划算的，花费人力物力财力做出来的 app，可能还没人用。那就瞎了。所以毋庸置疑，一拍即合，用第三方的。就开始了对于目前市面上主流的第三方 IM SDK 进行调研。其中有腾讯云，网易云信，融云，环信等。列出了一堆对比条件，最后领导拍板用哪个。末端程序员是没有选择权的。好好搬砖就可以了~要明白自己的身份，嘎嘎 过程不说了，最后选择了用融云，废话不多说，直接勒~这里只介绍一下如何快速集成，让俩人聊起来，这也算是一个里程碑啊。对于程序员来说，聊不起来可就毁了，领导都特么奶凶奶凶的~~~ 1.先到融云官网 进行注册，这个可以让你们产品经理或者啥领导去做，可以用公司的邮箱，别用自己的吧，后期自己换了地儿，对公司也是损失不是。注册后添加应用，拿到 appkey 2.xcode 创建一个新工程，或者找自己公司的项目，这里我推荐使用 pod 方式管理第三方，方便快捷，省时省力。因为手动方式太落后了，且配置繁琐，稍有遗漏就会报错，有些报错排查起来费时费力费心费电，所以还是老老实实的用 pod 吧。不听老人言，吃亏在眼前，听哥的没错，融云文档写了如何用 pod，几行命令的事。弄完后，也就是把 SDK 集成好了，跑一下工程，如果不报错，祝贺你兄嘚，马上可以聊天了，看下一步 3.需要在 appDelegate

排查指南 | 关于 mPaaS-iOS 小程序打不开问题的解决方案

由 风格不统一 提交于 2020-12-15 10:32:11
简介： 让天下没有打不开的小程序！！！ 在我们集成 mPaaS 插件并使用小程序的过程中，很多开发者遇到了打不开小程序的问题。今天就举例说明，开发者在完成基本接入后，尝试打开 H5 应用，但容器页面显示错误提示“设置标签”时，应该如何解决。 常见原因 mPaaS 框架在打开一个H5应用前，首先需要获知该应用离线包的基本信息。 因此客户端会主动通过RPC接口alipay.client.getUnionResource去拉取离线包信息。如果离线包信息获取失败，或没有命中要打开的目标应用，容器会提示错误 “系统繁忙，请稍后再试”。 针对这类问题，排查方向包括：检查 RPC 请求是否正常、检查环境和离线包发布是否匹配等。 问题排查步骤 （一）检查 RPC 请求是否正常 客户端需要主动拉取离线包信息，而拉取过程依赖 RPC 请求，如果RPC 链路存在问题，则无法正常获取离线包信息，导致加载失败。要确认 RPC 请求是否存在问题，需要在 Xcode 控制台中搜索 alipay.client.getUnionResource 观察 RPC 请求是否正常返回。如果存在错误，一般的错误代码包括 7XXX 或 3XXX 系列等，例如： 正常返回样例（result-status 为 1000）： Demo[83767:2555863] [mPaaSLog] APMobileNetwork alipay
