更改以编程方式创建的UISearchBar的字体

Question

I have found that the code in my AppDelegate :

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil]
 setFont:[UIFont systemFontOfSize:14]];

works to change the font of a UISearchBar created from IB. No problems there.

However, if I create the UISearchBar in code as such:

UISearchBar *bar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
bar.placeholder = @"test";
[self.view addSubview:bar];

Then the above UITextField appearance code has no effect. Is there a way to change the font of a programmatically created UISearchBar ?

Thank you!

Answer 1

尝试一下，它在iOS 5.0及更高版本上运行良好：（也适用于iOS 7）

[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setFont:[UIFont fontWithName:@"League Gothic" size:20]];

Answer 2

You can try this

UITextField *textField = [[searchBar subviews] objectAtIndex:1];
[textField setFont:[UIFont fontWithName:@"Helvetica" size:25]];

Answer 3

You can use this

UITextField *textField = [self.searchBar valueForKey: @"_searchField"];
[textField setFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:17.0]];

Hope this will help.
