如何通过代码将UISearchBar设置为黑色半透明？

Question

I know how to do this using IB, but how can I do this with just code? OR do I manually have to do the RGB?

I have:

UISearchBar * searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)];

Answer 1

You need to use the barStyle property and translucent properties together:

UISearchBar * searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)];
searchBar.barStyle = UIBarStyleBlack;
searchBar.translucent = YES;

Answer 2

I believe you can just do the following:

searchBar.barStyle = UIBarStyleBlackTranslucent;

Kool have fun :)

Answer 3

You should be able to do this via two properties in UISearchBar;

@property(nonatomic, retain) UIColor *tintColor
@property(nonatomic, assign, getter=isTranslucent) BOOL translucent

Set the tintColor to black, and set translucent to YES.

Check the reference for more info: http://developer.apple.com/library/iOS/#documentation/UIKit/Reference/UISearchBar_Class/Reference/Reference.html

Hope this does the trick!
