(1) download the ipa installation package on the 91 assistant and other websites. For Android, it should be in apk format. This is only for iOS. For example, download it to your computer.

(2) find it and right-click "ARCHIVE", which is equivalent to decompression.

(3) Finally, find the decompressed file, right-click the package content, and the resources are all in it.

Or install iTools, back up the app on your phone to your computer, and then perform the same operation.

How can I develop applications on the iOS operating platform?

App development on the IOS platform is mobile development and requires the following:
1. first, you must have a development platform, that is, development tools. IOS platform development tools are provided by Apple, including Xcode, Interface Builder, Instruments, and IOS simulators, these have been integrated into the Xcode development tool. The current version is more than 4 o'clock, that is, the Xcode development tool is required.
2. The above is a development tool. At present, the development tool only provides the Mac operating system version, and does not have Xcode development tools under the Windows operating system. Therefore, to use Xcode as a development tool, you must use the Mac operating system. To put it simply, you need an Apple computer, which is expensive. There are two other ways: (1) install the Apple system in your computer, which is commonly known as the Black apple. (2) install the apple System in the virtual machine. This mainly depends on whether your computer configuration is good enough, install a virtual machine, and then install the apple System in the virtual machine.
3. With the Mac operating system, and then installing the Xcode development environment in the Mac operating system, your entire IOS development environment is ready.
4. furthermore, it is the programming content. Apple applications use the Objective-C programming language. Normally, if you have the basics of a programming language (such as C/C ++ and java) and then learn Objective-C, you will learn the language faster, you can write the application code in the development environment.
5. You are familiar with the basic development environment, the development language, and then you can learn something deeper, such as some development frameworks.
6. real machine testing: After you write out the available programs, you need to perform a real machine test on your applications. At this time, you need devices with IOS operating systems, such as Iphone, Ipad, and Itouch.

This is probably the case. Score. Thank you!
