iOS è una struttura statica o dinamica?

Question

Questa potrebbe sembrare una domanda stupida, ma se si dispone di un file thirdParty.framework, puoi dire se è statico o dinamico? Voglio dire, hanno un aspetto diverso se guardi dentro?

Answer 1

Può essere o.

Solo iOS8 + consente i framework dinamici nel pacchetto di app, tuttavia.

Il modo per scoprirlo è quello di guardare in .framework e utilizzare il comando file sul file principale:

$ cd iOS/Crashlytics.framework 
$ ls -l 
total 9984 
-rwxr-xr-x 1 andy staff 4710656 11 Sep 17:11 Crashlytics 
drwxr-xr-x 8 andy staff  272 11 Sep 17:11 Headers 
-rw-r--r-- 1 andy staff  1553 11 Sep 17:11 Info.plist 
drwxr-xr-x 3 andy staff  102 11 Sep 17:11 Modules 
-rwxr-xr-x 1 andy staff 146164 11 Sep 17:11 run 
-rwxr-xr-x 1 andy staff 241688 11 Sep 17:11 submit 
$ file Crashlytics 
Crashlytics: Mach-O universal binary with 5 architectures 
Crashlytics (for architecture armv7): current ar archive random library 
Crashlytics (for architecture armv7s): current ar archive random library 
Crashlytics (for architecture i386): current ar archive random library 
Crashlytics (for architecture x86_64): current ar archive random library 
Crashlytics (for architecture arm64): current ar archive random library 

Dove ar archive significa "libreria statica".
