IOS development UI debugging artifacts ---- Reveal, ios ---- reveal

UI is a very important part of iOS development. During debugging, we generally use a simulator to perform testing on a real machine before submission. Although it is quick and convenient to debug the UI effect using a simulator, it is still expected to have more powerful tools to help analyze the UI, especially when debugging the UI effect. Recently, I saw the Reveal tool and found that it is really powerful. Similar to FireBug on FireFox, the display on the UI Layer is clear and intuitive and can be conveniently used for UI debugging, it is also a powerful tool to learn how to use the UI.

This tool is now available in the official version and requires money to purchase. Fortunately, you can download the trial version for 30 days. (Http://revealapp.com), it is said that there is a free Beta version in the past, which is big if there is, please share it with me, thank you.

Installing Reveal is not complicated. To use Reveal in the project, you need to compile the framework or dylib.

1. Open the Xcode Project

2. Open the Revel tool and select Menu-> Help-> Show Reveal Library in Finder to open the Library in RevealApp.

3. Add Reveal. framework to the project. In the pop-up box, select Copy items into destination group's folder (if needed ).

4. In the Project Settings, add-ObjC-framework Reveal to the Other Linker Flags item.

If you are still using Xcode4, you also need to add-frame CFNetwork-frame QuartzCore-framework CoreGraphics

5. you can run your application on a simulator or on a real machine, but you must ensure that Reveal and your device are in the same network, and then select the Link Target in Reveal, after the application is connected, the UI is displayed. Each layer and element can be displayed and the data can be viewed.

The description here is to link Reveal to the application as a static library, or load it as a dynamic library. Of course, the settings are slightly different and need to be in AppDelegate. add the load and remove code to the m file.

The most powerful thing is that some people have developed a Reveal method to watch the UI of any app, and it is not complicated. This method belongs to the category of reverse engineering, in the UI learning is still good (http://c.blog.sina.com.cn/profile.php? Blogid = cb8a22ea89000gtw ).

In IOS development, how do I debug the interface? Must I buy a device for debugging?

There is no need for a real machine, as long as you have a simulator, you can adjust the resolution yourself.
 
Ios development problems

UI development is purely a custom control. Custom views tend to be visually displayed by users, mainly for CAAnimation and CALayer.
For example, your boss may ask you to create a TableView in the ListView (Android platform) style. At this time, you are doing a typical UI development.
Application development mainly involves program logic, Socket, and video processing frameworks. Your program runs behind and what you cannot see. For example, if your program requires webservice communication, you need to perform network processing.
The game is complicated. Basically, you need to use all of the above two.
