In this article we will show you 10 questions you might want to ask before developing the iOS platform (iPhone, ipad, ipod) application. 1. Which platform should we target?

We all know that using macros is not only convenient, but also can improve development efficiency. Here's a summary of some of the common macros in the iOS development process that will continue to be added. Objective-c Whether the string is empty #define KSTRINGISEMPTY (str) ([str iskindofclass:[nsnull class]] | | |-str = NIL | | [STR length] 1.
