A lot of people jailbreak their iOS device in order to unlock it to play games for free and that means all the game resources(textures, models,etc) can be utilized by anyone else. Is there any way to put the resources into a package or other formats in unity to avoid cracking on iOS? Thanks a lot!

This isn’t really true.
When you build a project for iOS from Unity it compiles and packages up everything (some obfuscation is performed also).
These hackers tend to just work out what copy protection you have to prevent it running on the jailbroken device. They aren’t interested and typically don’t bother with trying to extract the texture and model resources.
In saying that however you could utilize AssetBundles to distribute assets post installation.
