iOS - Customizing Cancel button of UISearchBar - ios

Question

In my iOS5 iPhone application, i'm setting the tint color of search bar using following code:
searchBar.tintColor = UIColorMake(#"#EFEFEF");
RGB value of #efefef is (239,239,239)
Its working fine. But when cancel button appears the text "Cancel" is not visible. Can I customize only the cancel button with transparent black and white text on that?
is it possible to customize?

Answer 1

You can customize the Cancel button on iOS 5 by using the appearance proxy.
You need to change appearance of UIBarButtonItem when contained in UISearchBar.
For example to change the title font of the Cancel button you can use:
NSDictionary *attributes =
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor], UITextAttributeTextColor,
[UIColor colorWithRed:0 green:0 blue:0 alpha:0.5], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset,
[UIFont systemFontOfSize:12], UITextAttributeFont,
nil];
[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil]
setTitleTextAttributes:attributes forState:UIControlStateNormal];
[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil]
setTitleTextAttributes:attributes forState:UIControlStateHighlighted];

Answer 2

You could search for UISearchBar subViews and locate the cancel button, it is dangerous to do so, since the button could change
For example you could add this in your viewWillAppear
- (void) viewWillAppear:(BOOL)animated
{
//show the cancel button in your search bar
searchBar.showsCancelButton = YES;
//Iterate the searchbar sub views
for (UIView *subView in searchBar.subviews) {
//Find the button
if([subView isKindOfClass:[UIButton class]])
{
//Change its properties
UIButton *cancelButton = (UIButton *)[sb.subviews lastObject];
cancelButton.titleLabel.text = #"Changed";
}
}
}
As i said before this could change, its a hack to do so, you better stick with the original, or create your own search bar.

Answer 3

Since iOS5 you can edit the Navigationbar, Toolbar, Tabbar and some more with this code...
NSDictionary *textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor darkGrayColor],
UITextAttributeTextColor,
[UIColor whiteColor],
UITextAttributeTextShadowColor, nil];
[[UINavigationBar appearance] setTitleTextAttributes:textTitleOptions];
I haven´t tested it with a searchbar, but it should work similar.

Answer 4

This method works in IOS7
for (UIView *view in searchBar.subviews)
{
for (id subview in view.subviews)
{
if ( [subview isKindOfClass:[UIButton class]] )
{
// customize cancel button
UIButton* cancelBtn = (UIButton*)subview;
[cancelBtn setEnabled:YES];
break;
}
}
}
