How to change Searchbar's Placeholder font and size in iOS13

Swift 5:

 if let textfield = searchBar.value(forKey: "searchField") as? UITextField {
                let atrString = NSAttributedString(string: "Search",
                                                   attributes: [.foregroundColor : color,
                                                                .font : UIFont.systemFont(ofSize: 10, weight: .bold)])
                textfield.attributedPlaceholder = atrString

            }

How to change text color of PlaceHolder in UISearchBar? (iOS 13)

As you already mentioned, your code works only in viewDidAppear, which makes the placeholder to flicker from the default gray color to the preferred color.

However, there seem to be a time before viewDidAppear (I couldn't figure it out when exactly), to change the placeholder before the view actually appears.

I suppose, this may be connected to how iOS handles light/dark mode and/or an iOS bug.

The solution I came out with that works around the issue:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if #available(iOS 13.0, *) {
        let placeholder = NSAttributedString(string: "Search",
                                             attributes: [
                                                .foregroundColor: UIColor.white
        ])
        let searchTextField = searchBar.searchTextField

        // Key workaround to be able to set attributedPlaceholder
        DispatchQueue.global().async {
            DispatchQueue.main.async {
                searchTextField.attributedPlaceholder = placeholder
            }
        }
    }
}

There seem to be no performance and/or other downside to this method.

If anybody else comes with a better approach, feel free to collaborate.

UISearchBar change placeholder color

for iOS5+ use the appearance proxy

[[UILabel appearanceWhenContainedIn:[UISearchBar class], nil] setTextColor:[UIColor redColor]];

How can I change the UISearchBar search text color?

You have to access the UITextField inside the UISearchBar. You can do that by using valueForKey("searchField")

var textFieldInsideSearchBar = yourSearchbar.valueForKey("searchField") as? UITextField

textFieldInsideSearchBar?.textColor = yourcolor

Swift 3 update

let textFieldInsideSearchBar = yourSearchbar.value(forKey: "searchField") as? UITextField

textFieldInsideSearchBar?.textColor = yourcolor

How to change inside background color of UISearchBar component on iOS

Use this code to change the searchBar's UITextField backgroundImage:

UITextField *searchField;
NSUInteger numViews = [searchBar.subviews count];
for (int i = 0; i < numViews; i++) {
    if ([[searchBar.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
        searchField = [searchBar.subviews objectAtIndex:i];
    }
}
if (searchField) {
    searchField.textColor = [UIColor whiteColor];
    [searchField setBackground: [UIImage imageNamed:@"yourImage"]]; //set your gray background image here
    [searchField setBorderStyle:UITextBorderStyleNone];
}

Use the below code to change the UISearchBarIcon:

 UIImageView *searchIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourSearchBarIconImage"]];
searchIcon.frame = CGRectMake(10, 10, 24, 24);
[searchBar addSubview:searchIcon];
[searchIcon release];

Also, to change the searchBar icon you can use the following built-in method on UISearchBar (which is available from iOS 5+):

- (void)setImage:(UIImage *)iconImage forSearchBarIcon:(UISearchBarIcon)icon state:(UIControlState)state

Here you can set 4 types of UISearchBarIcon i.e.:

1. UISearchBarIconBookmark
2. UISearchBarIconClear
3. UISearchBarIconResultsList
4. UISearchBarIconSearch

I hope this help you...
