IOS---uitableviewcell adaptive row height (non-AutoLayout)

Title, the program is to use non-AutoLayout write UITableView adaptive Row height, after the author will write a AutoLayout based on the adaptive row height of the small demo.
PS: This applet only applies to children who just touch iOS, only for reference, no technical, big God do not spray.
