Hardware adaptation for iOS devices (for armv6, armv7, and armv7s, I think it is clear)

1. OpenGL ES version support

IPhone: devices of the iPhone 3G or earlier versions (including the iPhone 3g) only support OpenGL es1.1. devices of the iPhone 3gs or later versions (including the iPhone 3gs) Support OpenGL es1.1 and OpenGL es2.0. IPad: All iPad versions support OpenGL es1.1 and OpenGL es2.0. IPod Touch: IPOD touch2 (including iPod touch2) version devices only support OpenGL es1.1, iPod touch3 (including iPod touch3) version devices support OpenGL es1.1, openGL es2.0 is also supported, but 8 GB iPod touch3 generation does not support OpenGL es2.0. 2. armv6, armv7, and armv7s
Armv6: iPhone 2g/3G, iPod 1g/2G Armv7: iPhone 3gs/4/4S, iPod 3g/4G, iPad 1g/2g/3G Armv7s: iphone5
I personally think For this part of contentCodeIf the armv7s error is reported during a real machine test, the reason is that the armv7 command is enabled, go to xcode --> "build Settings" --> "valid ubuntures" and remove armv7s. Of course, the best way is to think about how to be compatible with armv7s, because after removing this setting, I personally think it may makeProgramUnable to run on iPhone 5, Because I do not have an iPhone 5, I cannot test this conjecture. Please use the iPhone 5 to answer my questions by the way. Thank you!
