swift -> solve the problem of slow display of code prompts

 

 

** It should be a BUG problem, as follows

let search_bar_box = UIView(frame: CGRect(x: 10, y: 10, width: screenWidth-boxMargin*2-10*2, height: 80-10*2));

 

If changed to

 

let search_bar_box = UIView(frame: CGRect(x: 10, y: 10, width: 80, height: 60));

 

Alternatively, define width and height as variables first 

let width = screenWidth-boxMargin*2-10*2;
let search_bar_box = UIView(frame: CGRect(x: 10, y: 10, width: width, height: 80-10*2));

will solve the problem.
