i don't know how modify original searchicon's color.

enter image description here

you can use custom image of white search icon, search bar not modify supplied image. set custom image, use method. (link documentation.)

- (void)setimage:(uiimage *)iconimage forsearchbaricon:(uisearchbaricon)icon            state:(uicontrolstate)state;

example code: 

[searchbar setimage:[uiimage imagenamed:@"searchicon"]    forsearchbaricon:uisearchbariconsearch               state:uicontrolstatenormal];

in swift: 

searchbar.setimage(uiimage(named: "searchicon"), for: .search, state: .normal)
