Touch through UIImageView?

由 流过昼夜 提交于 2020-01-14 07:29:05
问题 I have a transparent UIImageView with a button behind it. How can I touch "through" it and press the button underneath it? Thanks 回答1: Use UIImageView.userInteractionEnabled = NO; That prevents it from receiving touches and all the touches will go through it. 来源： https://stackoverflow.com/questions/7060410/touch-through-uiimageview

UUID is unique? iphone

由 南笙酒味 提交于 2020-01-14 05:57:12
问题 Can i save an UUID in an external database in order to check if the user posts his message only one time from his iphone? I have searched and i have found that there is no way to save a NSString value after the app has been deleted. Am i right? 回答1: When an app is deleted, all of its data is deleted too. You could store the UUID on a remote server, however the iPhone's UUID will be the same regardless of how many times your app is deleted and reinstalled. Note that this can be a security

Compose a Message with predefined link attached from iOS app into Facebook Messenger

由 六眼飞鱼酱① 提交于 2020-01-14 05:52:07
问题 I am using fb-messenger://compose to open Facebook Messenger Composer, but I need to attach a predefined link into the composer. I don't want to use action sheet for that. I also saw this answer - Facebook Messenger Compose Predefined Message Which may seem similar but is a wrong answer because it is Facebook SDK and not Facebook Messenger. I looked at Facebook Messenger SDK for iOS - https://developers.facebook.com/docs/messenger/ios under Basic Integration \ Sharing Content and all I could

iPhone SDK Present Value function

由 核能气质少年 提交于 2020-01-14 05:45:27
问题 Present value is the value on a given date of a future payment or series of future payments, discounted to reflect the time value of money and other factors such as investment risk. Present value calculations are widely used in business and economics to provide a means to compare cash flows at different times on a meaningful "like to like" basis. http://en.wikipedia.org/wiki/Present_value What would be the best way to tackle this in an Objective-C function? double retire62 = [benefit62.text

Add statements for higher version?

由 ☆樱花仙子☆ 提交于 2020-01-14 01:56:32
问题 I am using 1.6 i.e. API 4 to build my application. There are couple of commands that are supported by higher versions. I want to write those commands and make application more compatible for higher versons. Like, I use Tabs. I want to use setLeftStripDrawable and setRightStripDrawable, but they are supported by API 8. I write something like : // I want these lines to come into affect only if the device SDK is greater than 7 as SDK of below 7, doesn't support these methods. if (android.os

如何在 .NET 项目中开启不安全代码（以便启用 unsafe fixed 等关键字）

由 二次信任 提交于 2020-01-14 01:54:45
有小伙伴希望在 .NET 代码中使用指针，操作非托管资源，于是可能使用到 unsafe fixed 关键字。但使用此关键字的前提是需要在项目中开启不安全代码。 本文介绍如何在项目中开启不安全代码。 本文内容 入门方法 高级方法 临时方法 其他说明 入门方法 第一步：在你需要启用不安全代码的项目上点击右键，然后选择属性： 第二步：在“生成”标签下，勾选上“允许不安全代码”： 第三步：切换到 Release 配置，再勾上一次“允许不安全代码”（确保 Debug 和 Release 都打开） 方法结束。 如果你一开始选择了“所有配置”，那么就不需要分别在 Debug 和 Release 下打开了，一次打开即可。 高级方法 推荐 如果你使用 .NET Core / .NET Standard 项目，那么你可以修改项目文件来实现，这样项目文件会更加清真。 第一步：在你需要启用不安全代码的项目上点击右键，然后选择编辑项目文件： 第二步：在你的项目文件的属性组中添加一行 <AllowUnsafeBlocks>true</AllowUnsafeBlocks> ： 我已经把需要新增的行高亮出来了 <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework

esp8266 SDK开发之编译流程

由 丶灬走出姿态 提交于 2020-01-13 21:06:21
最近刚完成自己8266的小项目，已经发布在github上，有兴趣的朋友可以看一下 github地址： esp-ujn 1. 通过MQTT协议与服务器交互 2. 内置HTTP服务器，支持通过浏览器进行参数配置 编译流程分析 我们在编译8266代码时可以使用项目中的 gen_misc.sh （Windows下为 gen_misc.bat ）脚本，选择合适的参数后就会在 sdk/bin/ 文件夹中生成可烧录的文件，如 eagle.flash.bin ， eagle.irom0text.bin 。 但这样存在的问题是每次编译时都需要选择一遍编译参数，所以一般会使用 make 命令进行编译，如： make COMPILE=gcc BOOT=none APP=0 SPI_SPEED=40 SPI_MODE=QIO SPI_SIZE_MAP=4 这是因为 gen_misc.sh 的作用仅仅是供用户选择编译参数，最终的编译过程是通过 make 命令依据Makefile文件中定义的若干规则来进行的。接下来通过如下几个方面来探讨整个编译流程 Makefile的组织形式 烧录文件的生成过程 Makefile的执行过程 一、Makefile的组织形式 SDK中Makefile文件以树形结构组织。总体上分为3类：主文件，项目配置文件，库配置文件。 |--sdk/ |----Makefile |---

Firefox 5, 6, 7 and XULRunner: Which versions are which?

由 会有一股神秘感。 提交于 2020-01-13 20:35:32
问题 I'm trying to recompile a Firefox extension that has binary components for use with Firefox 5 now that the beta is out. According to this I need to rebuild the binary components. What I can't figure out is which xulrunner to download and build against from here. Is there a table that matches up FF versions (5, 6, 7) with code names (Beta, Central, Aurora) with Xul Runner versions (2, etc)? Any decent guide would be great. Update It looks like the SDK / Mozilla version number has been changed

Are Flex charts available in the free Flex SDK?

由 只谈情不闲聊 提交于 2020-01-13 19:22:23
问题 Hmmmm... It appears that charts are only available through the Flex SDK that comes built-in with Flex Builder. This is a problem, since I want to use Flex 3.3, and Flex Builder came with 3.2. Eclipse is also ticking me off, and I prefer to use a different IDE (FlashDevelop). Any way around this? And is there anything else that isn't included the the free SDK that I should be aware of? 回答1: The charts are only available with the professional Flex Builder plugin. If you have a FB license,

vlc-android编译

首先关于什么是vlc我这里就不多介绍了，毕竟搜索到这里的大家都是知道的。 这两天一直在弄vlc android的编译，确实很多坑，但是好在最后还是编译出来了(SDK APP我是没编译出来毕竟对Gradle之类的不太懂) 编译一律参考官方wiki https://wiki.videolan.org/AndroidCompile/ 下面给大家介绍一下我的编(cai)译(keng)历程 环境ubuntu 18.04 (1) 按照官方wiki说的安装一些包 (2) SDK与NDK的安装与配置 NDK下载地址： https://developer.android.google.cn/ndk/downloads/older_releases.html 这里需要参考官方的说明来选择下载的包，比如我编译的版本需要NDK r18b SDK下载，这里就不要单独下载SDK了最简单的方法就是下载Android Studio这位大哥会帮您把SDK给下载完毕的 下载地址: https://developer.android.google.cn/studio/#downloads NDK解压完，Android Studio安装完以后呢，就要配置一下对应的环境变量 在home目录下 然后在文档的最后加入 当然这是我的路径，您还得根据自己的实际情况修改路径 使环境变量生效 (3) JDK的安装与配置
