How to add a 1 pixel gray border around a UISearchBar TextField

Question

I\'m trying to figure out how to add a 1 pixel stroke gray border to my UISearchBar in my app. The Facebook Messenger app accomplishes this quite well. (see pic below).

Answer 1

Try this code:

//First add the following import and macro:
#import 
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

//Then change yourSearchBar border: 
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
    for (id object in [[[yourSearchBar subviews] objectAtIndex:0] subviews])
    {
        if ([object isKindOfClass:[UITextField class]])
        {
            UITextField *textFieldObject = (UITextField *)object;
            textFieldObject.layer.borderColor = [[UIColor grayColor] CGColor];
            textFieldObject.layer.borderWidth = 1.0;
            break;
        }
    }
}
else
{
    for (id object in [yourSearchBar subviews])
    {
        if ([object isKindOfClass:[UITextField class]])
        {
            UITextField *textFieldObject = (UITextField *)object;
            textFieldObject.layer.borderColor = [[UIColor grayColor] CGColor];
            textFieldObject.layer.borderWidth = 1.0;
            break;
        }
    }
}
