IOS uisearchbar Modify placeholder font color and size

When I modify the placeholder font color above the searchbar, my own handwritten code is exactly the same as the correct one, it doesn't recognize it, it always collapses, and the wrong content says it's not the value, it's a hell of a thing.

 Self.searchbar = [[Uisearchbar alloc]initwithframe:cgrectmake (kuiscreen_width-40, 30)];
    _searchbar.placeholder = @ "qualified";
    _searchbar.tintcolor = [Uicolor Whitecolor];
    _searchbar.translucent = YES;
    _searchbar.layer.maskstobounds = YES;
    _searchbar.layer.cornerradius = 5.0;
    _searchbar.alpha = 0.2;
    Add a background image, you can remove the gray part of the outer box [_searchbar setbackgroundimage:[uiimage New]];

    [_searchbar Settranslucent:yes];
    This enumeration can be modified for searchbar _searchbar.searchbarstyle = uisearchbarstyleprominent;
