One less editor to pack in build Setting

Build Active Architecture Only sets Release to NO to contain all compilers

This property is set to YES for faster compilation on Debug, which only compiles the current architecture version.

and set to no, all versions are compiled.

this is the architecture corresponding to the device:

  
ARMv8/ARM64: iPhone 6(Plus), iPhone 5s, iPad Air(2), Retina iPadMini(2,3)
   
ARMv7s: iPhone 5, iPhone 5c, iPad 4 
   
ARMv7: iPhone 3GS, iPhone 4, iPhone 4S, iPod 3G/4G/5G, iPad, iPad2, iPad 3, iPadMini   
   
ARMv6: iPhone, iPhone 3G, iPod 1G/2G
  

The compiled version is backward compatible. For example, if you set this value to yes, the compiled version with iphone4 will run with armv7, and iphone5 will also run, but the device with armv6 will not.

therefore, debug can choose to set to yes, release to no, to adapt to different devices.

• delete the cached data (Organizer-> Projects-> Derived Data tap ‘Delete… ‘
• insure that for this XIB the proper versioning is set (select XIB, 3rd Xcode tab on right, File options:
• close the project
• quit Xcode
• reopen Xcode, then the product
• try again

when I use git push, hexo deploy and similar operations, I often see an error message ttyname failed: Inappropriate ioctl for device. How does this work, not 0 errors,0 warnings work?The solution to this problem is documented here.

problem cause

Ubuntu knows that not everyone will perform graphical logins on the root account, so in the default .profile file it is set to generate a false error in this case. As you can see, there is a line at the end of the /root/.profile.

mesg n || true

what is this?This is to prevent programs like talk from writing to your console, which is especially important if you are logging into your root account via a text session. || true is to prevent an error when the request for tty fails from causing the shell script to abort.

put this sentence in the .profile file, which allows you to execute this sentence every time you run bash. When you run from a painting without a TTY device, you will see an error, and this will not affect other programs, just a message will be displayed.

solution

is harmless, but it’s not comfortable to see the error message all the time, so get rid of it.

change /root/. Profile filemesg n || true to the following.

tty -s && mesg n || true

this allows mesg not to send a message when there is no tty, but to continue calling when there is one. Now you can see that ttyname failed: impatient ioctl for device.

I installed the python environment and PyQt5 library

---

solution:

CMD command line input PIP list to view the installed python library

1, first uninstall PyQt5, enter PIP uninstall PyQt5 to uninstall

2. Find the installation location of PyQt5 after uninstalling, and directly delete the folder

3. Delete environment variables

win10: this computer — > Property – & gt; Advanced system Setup — & GT; Advanced – & gt; Environmental variable — & GT; The system variable
removes the variable named QT_QPA_PLATFORM_PLUGIN_PATH
4. Delete and reinstall PyQt5

command PIP install PyQt5
(download slow if the command line, you can go to the website https://pypi.org/project/PyQt5/#files links from thunderbolt download, download after install, remember not to the right version, don’t know which version download can on the command line input PIP install PyQt5 enter, displays are behind the download version, I download file is the following version
)

5. Configure environment variables after installation, and restart the computer after configuration.

variable name: QT_QPA_PLATFORM_PLUGIN_PATH
variable value: C:(PyQt5 installation path)\Python\ python38-32 \Lib\site-packages\PyQt5\Qt\plugins
