The issue asks how to programmatically present the QMUISearchController search page. To answer, examine the QMUI iOS documentation and source code, particularly the QMUISearchController class and its usage in demo examples. Check if there is a public method like showSearch or presentSearchController. Look at the repository's demo app for patterns.
