Jak zmienić kolor tła komponentu UISearchBar w systemie iOS
Wiem jak usunąć / zmienić UISearchBar
kolor tła wokół pola wyszukiwania:
[[self.searchBar.subviews objectAtIndex:0] removeFromSuperview];
self.searchBar.backgroundColor = [UIColor grayColor];
Ale Nie wiem jak to zrobić w środku w ten sposób:
To musi być zgodne z iOS 4.3+.18 answers
Użyj tego kodu, aby zmienić pasek wyszukiwania 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];
}
Użyj poniższego kodu, aby zmienić UISearchBarIcon
:
UIImageView *searchIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourSearchBarIconImage"]];
searchIcon.frame = CGRectMake(10, 10, 24, 24);
[searchBar addSubview:searchIcon];
[searchIcon release];
Ponadto, aby zmienić ikonę paska wyszukiwania, możesz użyć następującej wbudowanej metody na UISearchBar
(która jest dostępna z iOS 5+):
- (void)setImage:(UIImage *)iconImage forSearchBarIcon:(UISearchBarIcon)icon state:(UIControlState)state
Tutaj możesz ustawić 4 typy UISearchBarIcon
tj.:
UISearchBarIconBookmark
UISearchBarIconClear
UISearchBarIconResultsList
UISearchBarIconSearch

Po prostu dostosuj samo pole tekstowe.
Po prostu to robię i działa dobrze dla mnie (iOS 7).
UITextField *txfSearchField = [_searchBar valueForKey:@"_searchField"];
txfSearchField.backgroundColor = [UIColor redColor];
W ten sposób nie trzeba tworzyć obrazu, rozmiar, itp...

Rozwiązanie, które nie obejmuje żadnego prywatnego API ! :)
Obecnie (prawdopodobnie od iOS 5 ) możesz to zrobić, dla jednego koloru, w ten sposób:
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setBackgroundColor:[UIColor redColor]];
Należy jednak pamiętać, że ze względu na wygląd zmiana będzie globalna dla aplikacji (może to być zaleta lub wada rozwiązania).
Dla Swift możesz użyć (będzie działać na iOS 9 i nowszych):
if #available(iOS 9.0, *) {
UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).backgroundColor = UIColor.darkGrayColor()
}
Nie potrzebujesz #available
Jeśli twój projekt obsługuje iOS 9 i nowsze.
Jeśli potrzebujesz wsparcia dla wcześniejszych wersji iOS i chcesz korzystać z Swift spójrz na to pytanie.

Rozszerzenie UISearchBar
extension UISearchBar {
private func getViewElement<T>(type: T.Type) -> T? {
let svs = subviews.flatMap { $0.subviews }
guard let element = (svs.filter { $0 is T }).first as? T else { return nil }
return element
}
func setTextFieldColor(color: UIColor) {
if let textField = getViewElement(type: UITextField.self) {
switch searchBarStyle {
case .minimal:
textField.layer.backgroundColor = color.cgColor
textField.layer.cornerRadius = 6
case .prominent, .default:
textField.backgroundColor = color
}
}
}
}
Użycie
let searchBar = UISearchBar(frame: CGRect(x: 0, y: 20, width: UIScreen.main.bounds.width, height: 44))
//searchBar.searchBarStyle = .prominent
view.addSubview(searchBar)
searchBar.placeholder = "placeholder"
searchBar.setTextFieldColor(color: UIColor.green.withAlphaComponent(0.3))
Wynik 1
searchBar.searchBarStyle = .prominent // or default
Wynik 2
searchBar.searchBarStyle = .minimal

Zgodnie z UISearchBar documentation :
Powinieneś użyć tej funkcji dla iOS 5.0+.
- (void)setSearchFieldBackgroundImage:(UIImage *)backgroundImage forState:(UIControlState)state
Przykład użycia:
[mySearchBar setSearchFieldBackgroundImage:myImage forState:UIControlStateNormal];
Niestety, w iOS 4 musisz wrócić do mniej wyrafinowanych metod. Zobacz inne odpowiedzi.Warning: date(): Invalid date.timezone value 'Europe/Kyiv', we selected the timezone 'UTC' for now. in /var/www/agent_stack/data/www/doraprojects.net/template/agent.layouts/content.php on line 54

Jak mówi Accatyyc dla iOS5 + użyj setSearchFieldBackgroundImage, ale albo musisz utworzyć grafikę, albo wykonaj następujące czynności:
CGSize size = CGSizeMake(30, 30);
// create context with transparent background
UIGraphicsBeginImageContextWithOptions(size, NO, [UIScreen mainScreen].scale);
// Add a clip before drawing anything, in the shape of an rounded rect
[[UIBezierPath bezierPathWithRoundedRect:CGRectMake(0,0,30,30)
cornerRadius:5.0] addClip];
[[UIColor grayColor] setFill];
UIRectFill(CGRectMake(0, 0, size.width, size.height));
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[self.searchBar setSearchFieldBackgroundImage:image forState:UIControlStateNormal];

A co z apple way?
UISearchBar.appearance().setSearchFieldBackgroundImage(myImage, for: .normal)
Możesz ustawić dowolny obraz na swoim projekcie!
Ale jeśli chcesz utworzyć cały programmaticle, ca zrobić to
Moje rozwiązanie na Swift 3
let searchFieldBackgroundImage = UIImage(color: .searchBarBackground, size: CGSize(width: 44, height: 30))?.withRoundCorners(4)
UISearchBar.appearance().setSearchFieldBackgroundImage(searchFieldBackgroundImage, for: .normal)
Gdzie używam helpers extension
public extension UIImage {
public convenience init?(color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) {
let rect = CGRect(origin: .zero, size: size)
UIGraphicsBeginImageContextWithOptions(rect.size, false, 0.0)
color.setFill()
UIRectFill(rect)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
guard let cgImage = image?.cgImage else { return nil }
self.init(cgImage: cgImage)
}
public func withRoundCorners(_ cornerRadius: CGFloat) -> UIImage? {
UIGraphicsBeginImageContextWithOptions(size, false, scale)
let rect = CGRect(origin: CGPoint.zero, size: size)
let context = UIGraphicsGetCurrentContext()
let path = UIBezierPath(roundedRect: rect, cornerRadius: cornerRadius)
context?.beginPath()
context?.addPath(path.cgPath)
context?.closePath()
context?.clip()
draw(at: CGPoint.zero)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext();
return image;
}
}

Uznałem, że jest to najlepszy sposób na dostosowanie wyglądu różnych atrybutów paska wyszukiwania w Swift 2.2 i iOS 8 + za pomocą UISearchBarStyle.Minimal
searchBar = UISearchBar(frame: CGRectZero)
searchBar.tintColor = UIColor.whiteColor() // color of bar button items
searchBar.barTintColor = UIColor.fadedBlueColor() // color of text field background
searchBar.backgroundColor = UIColor.clearColor() // color of box surrounding text field
searchBar.searchBarStyle = UISearchBarStyle.Minimal
// Edit search field properties
if let searchField = searchBar.valueForKey("_searchField") as? UITextField {
if searchField.respondsToSelector(Selector("setAttributedPlaceholder:")) {
let placeholder = "Search"
let attributedString = NSMutableAttributedString(string: placeholder)
let range = NSRange(location: 0, length: placeholder.characters.count)
let color = UIColor(white: 1.0, alpha: 0.7)
attributedString.addAttribute(NSForegroundColorAttributeName, value: color, range: range)
attributedString.addAttribute(NSFontAttributeName, value: UIFont(name: "AvenirNext-Medium", size: 15)!, range: range)
searchField.attributedPlaceholder = attributedString
searchField.clearButtonMode = UITextFieldViewMode.WhileEditing
searchField.textColor = .whiteColor()
}
}
// Set Search Icon
let searchIcon = UIImage(named: "search-bar-icon")
searchBar.setImage(searchIcon, forSearchBarIcon: .Search, state: .Normal)
// Set Clear Icon
let clearIcon = UIImage(named: "clear-icon")
searchBar.setImage(clearIcon, forSearchBarIcon: .Clear, state: .Normal)
// Add to nav bar
searchBar.sizeToFit()
navigationItem.titleView = searchBar

Bez użycia prywatnych API:
for (UIView* subview in [[self.searchBar.subviews lastObject] subviews]) {
if ([subview isKindOfClass:[UITextField class]]) {
UITextField *textField = (UITextField*)subview;
[textField setBackgroundColor:[UIColor redColor]];
}
}

Lepszym rozwiązaniem jest ustawienie wyglądu UITextField
wewnątrz UISearchBar
[[UITextField appearanceWhenContainedIn:[UISearchBar class], nil] setBackgroundColor:[UIColor grayColor]];

Po prostu przejrzyj wszystkie widoki za pomocą metody kategorii (zweryfikowanej w iOS 7 i nie używającej prywatnego API):
@implementation UISearchBar (MyAdditions)
- (void)changeDefaultBackgroundColor:(UIColor *)color {
for (UIView *subview in self.subviews) {
for (UIView *subSubview in subview.subviews) {
if ([subSubview isKindOfClass:[UITextField class]]) {
UITextField *searchField = (UITextField *)subSubview;
searchField.backgroundColor = color;
break;
}
}
}
}
@end
Więc po zaimportowaniu kategorii do swojej klasy, użyj jej tak:
[self.searchBar changeDefaultBackgroundColor:[UIColor grayColor]];
Pamiętaj, że jeśli umieścisz tę natychmiast po linii [[UISearchBar alloc] init]
, to nie będzie ona jeszcze działać, ponieważ podglądy paska wyszukiwania są nadal tworzone. Umieść go kilka linii w dół po skonfigurowaniu reszty paska wyszukiwania.

// Override point for customization after application launch.
// Remove lag on oppening the keyboard for the first time
UITextField *lagFreeField = [[UITextField alloc] init];
[self.window addSubview:lagFreeField];
[lagFreeField becomeFirstResponder];
[lagFreeField resignFirstResponder];
[lagFreeField removeFromSuperview];
//searchBar background color change
[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setBackgroundColor:[UIColor greenColor]];
[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTextColor:[UIColor blackColor];
return YES;

@EvGeniy Ilyin rozwiązanie EvGeniy Ilyin jest najlepsze. Na podstawie tego rozwiązania napisałem wersję Objective-C.
Utwórz kategorię UIImage
i Zareklamuj dwie metody klas w UIImage+YourCategory.h
+ (UIImage *)imageWithColor:(UIColor *)color withSize:(CGRect)imageRect;
+ (UIImage *)roundImage:(UIImage *)image withRadius:(CGFloat)radius;
Zaimplementuj metody w UIImage+YourCategory.m
// create image with your color
+ (UIImage *)imageWithColor:(UIColor *)color withSize:(CGRect)imageRect
{
UIGraphicsBeginImageContext(imageRect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context, [color CGColor]);
CGContextFillRect(context, imageRect);
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
// get a rounded-corner image from UIImage instance with your radius
+ (UIImage *)roundImage:(UIImage *)image withRadius:(CGFloat)radius
{
CGRect rect = CGRectMake(0.0, 0.0, 0.0, 0.0);
rect.size = image.size;
UIGraphicsBeginImageContextWithOptions(image.size, NO, [UIScreen mainScreen].scale);
UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:rect
cornerRadius:radius];
[path addClip];
[image drawInRect:rect];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
Make your own UISearchBar
in your ViewController
CGRect rect = CGRectMake(0.0, 0.0, 44.0, 30.0);
UIImage *colorImage = [UIImage imageWithColor:[UIColor yourColor] withSize:rect];
UIImage *finalImage = [UIImage roundImage:colorImage withRadius:4.0];
[yourSearchBar setSearchFieldBackgroundImage:finalImage forState:UIControlStateNormal];
