The above code is manually implemented by adding 4 labels to the table cell and displaying the relevant content, running the effect

Another way to achieve this effect is to use storyboard, which is implemented with nib. However, before with a senior communication, I learned that in the future work with the code to achieve a more view layout, because it will solve a lot of problems. Before doing all of the use of storyboard, although now feel that it will be easier to use, but to the development of large-scale app when the Who know,right? Therefore, you also need to improve the ability to implement layout with code.
