ios9,10 no problem, iOS8 above a login on the crash, cause assets problem

In the project development, packaged into an IPA package, found ios9,10, running very smooth, iOS8 above a run on the crash, looking for a long time, just to find the reason is assets problem, a start I put IPA package on the dandelion above the host scan code download, with itunes is also Ben collapse, The whole person is not good, check the old and the most information to find the reason

Open the IPA unzip package to locate the file, and then copy it to the desktop for easy handling

Open Terminal input

sudo xcrun--sdk iphoneos assetutil--info/users/csmd/desktop/assets.car

Find the corresponding picture properties to see if there are conflicting views encoding ARGB

Another simple way is to remove the assets inside the project and re-add it to re-package the normal operation

One or more pictures caused by the bug this has a lot of holes again packaging will not assets.car this file

Everything OK
