What are the advantages of armv7 over armv6 when compiling iPhone apps?

由 怎甘沉沦 提交于 2019-11-27 05:00:14
问题 If there are any advantages at all... couldn't find anything conclusive in the docs. Apparently armv7 is for newer version of iOS... is it faster? smaller? Better at X? 回答1: One of the bigger differences is that the armv6 architecture has hardware support for double precision floating point arithmetic, while armv7 only provides legacy software support for double precision floating point arithmetic. To compensate, the armv7 architecture has a "NEON" unit that provides blindingly fast hardware

问题 I stumbled upon a problem on a project that I need to work on. The project use Cocoapods for managing its libraries. I run pod install as usual to get started but xcode give me errors.

I tried to remove all the Cocoapods related file from the project and running pod install again, but it still doesn't solved the

Why use armeabi-v7a code over armeabi code?

由 此生再无相见时 提交于 2019-11-26 21:26:21
In my current project I make use of multiple .so files. These are located at the armeabi and armeabi-v7a folder. Unfortunately one of the .so files is a 6MB and I need to reduce file size. Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder. According to the NDK documentation, armeabi-v7a code is extended armeabi code which can contain extra CPU instructions. This all goes beyond my expertise, but I question why one would like to have both armeabi-v7a and armeabi code. There must be a good reason to have both, right? On my test devices

What are all the supported ios devices that can run on armv7s and arm64. In other words, which market would i be excluding if I did not include armv7 in my build architectures? I'm curious about armv7s, not armv7. I thought this would be a basic google search but failing to find a clear answer. I find this as the best source for knowing basic of all iOS devices: Original Link: iOS Support Matrix PDF version: iOS Support Matrix PDF 4.4 NOTE: iOS Support Matrix is not updating the image very frequently. For up to date information use official Apple link given in the Reference section. Other

Building ffmpeg iOS libraries for armv7, armv7s, arm64, i386 and universal

由 混江龙づ霸主 提交于 2019-11-26 20:31:55
问题 I have seen several scripts to build FFmpeg API for armv7, 7s and i386 but couldn't find anything which would work for armv64 as well. Some of the answers on other threads of this forum suggested to prepare a separate library for arm64 but it does not work well with rest of the architectures. Hence I need a script which can work for all the supported architectures for iOS including armv7, armv7s, armv64 and i386. 回答1: I have use below scripts for making FFmpeg build for arm64 https://github

How to support both armv6 and armv7s for release build in xcode 4.5

由 空扰寡人 提交于 2019-11-26 00:56:49
问题 I know that this is not possible and Apple planned it this way to force the users to upgrade their devices. But I just want to know if there is some workaround or hacks in able to do this? The client insists that we should still support armv6 because of a still \"large\" percentage of the app users. I know a command called lipo to merge static libraries and I read somewhere that we can also use it to merge ipa files but I\'m not sure how its exactly done. I did a couple of searching around
