It is said that I can develop IOS apps on a computer that supports virtualization, while Object-C is quite different from Java (complicated ). But I have an IOS terminal and want to get something to play. So in addition to continuing to learn about Android, I also want to fix Object-C.
Let's talk a little about it. Next, let's take a look at our Learning conten

Android, these layouts are called ViewGroup objects, and each viewgroup contains one or more sets of view.Step TwoTo focus on the basics of a set of layouts, we want to remove all the existing content from the main layout file so that we can design from scratch. As we mentioned earlier, you can use Java code to create your own layouts or view, but many of the tools
