The iOS SDK project introduces third-party library Framework files

Problem: sometimes the.h file is not found

The reason is location.

Solution:

Method 1: Add an item to the project do not select Copy items if need

The diagram below:

#import

Method 2: Method 1: Add an item to the project Select Copy items if need, then import the head file as shown in the following figure:

#import < alipaysdk. h> or “alipaysdk.h”

Again, this is an SDK project, not a normal engineering project
