ARMv7 armv7s arm64

The ARM processor is known for its low power consumption and small size, and almost all handset processors are based on arm and are widely used in embedded systems.ARMv6, ARMv7, armv7s, arm64 refers to the instruction set of the ARM processor. i386, x86_64 refers to a PC-side processor instruction set.All instruction sets are in principle backwards compatible. arm64：iPhone6s | iphone6s plus｜iPhone6｜ iPhone6 plus｜iPhone5S | iPad Air｜ iPad mini2(iPad mini with Retina Display)
armv7s：iPhone5｜iPhone5C｜iPad4(iPad with Retina Display)
armv7：iPhone4｜iPhone4S｜iPad｜iPad2｜iPad3(The New iPad)｜iPad mini｜iPod Touch 3G｜iPod Touch4

i386是针对intel通用微处理器32位处理器
x86_64是针对x86架构的64位处理器

模拟器32位处理器测试需要i386架构，
模拟器64位处理器测试需要x86_64架构，
真机32位处理器需要armv7,或者armv7s架构，
真机64位处理器需要arm64架构。There are three main options related to the instruction set in Xcode:1,architectures: This option specifies the packets that the project can be compiled into to support which instruction set. Since the project compiles the corresponding binary packets for each instruction set, the more supported instruction sets, the greater the corresponding generated IPA package. 2,valid architectures: Limits the range of instruction sets that can be supported by the project. That is, the instruction set that the project ultimately supports is within the scope defined by valid architectures, so the set of instructions that the project eventually compiles will be determined by the intersection of the instruction set defined by the Architetures and valid architectures options.3,build Active Architecture only: Sets whether to compile only the set of instructions supported by the current connected device. In general, the debug time can be specified as Yes, in order to debug the time to compile faster, release when the time specified as no, to adapt to different devices.
