[英]Set rounded corners and border to background(Not the UITextField) of UISearchBar in ios7
[英]Remove Border of UISearchBar in iOS7
我正在尝试删除 iOS 7 中 UISearchBar 的边框。在 iOS 6 中它工作正常。 我以编程方式创建了 UISearchBar。 我尝试了几乎所有来自 Stack Overflow 和 Google 的东西。
SearchBar 正在寻找
我想要达到的目标
我尝试了下面提到的所有这些东西
searchBar.layer.borderWidth = 1;
searchBar.layer.borderColor = [[UIColor whiteColor] CGColor];
和
for (id img in searchBar.subviews)
{
if ([img isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
[img removeFromSuperview];
}
}
和
for (UIView *sub in self.tableView.tableHeaderView.subviews) {
if ([sub isKindOfClass:[UIImageView class]]) {
sub.hidden = YES;
}
}
但仍然没有成功。
在 IB 的搜索栏属性中设置搜索样式 = 最小
或者
Swift:
searchBar.searchBarStyle = UISearchBarStyleMinimal;
Swift 3:
searchBar.searchBarStyle = .minimal;
将 searchBarStyle 设置为 UISearchBarStyleMinimal 弄乱了我的颜色设置,因此这样做可以解决问题。
[self.searchField setBackgroundImage:[[UIImage alloc]init]];
对于那些在 Swift 4 中寻找这个选项的人:
searchField.setBackgroundImage(UIImage(), for: .any, barMetrics: UIBarMetrics.default)
对于 Swift,这两行就足够了:
self.search.isTranslucent = false
self.search.backgroundImage = UIImage()
然后,应用所需的颜色:
self.search.barTintColor = .red
我找到了解决方案:设置barTintColor
的UISearchBar
到clearColor
topSearchBar.barTintColor = [UIColor clearColor];
这仅适用于
.borderStyle = UITextBorderStyleLine
; .
我的实验结论,
如果你在 iOS7 及以上,并且如果你会设置, searchBar.barTintColor = [UIColor clearColor];
那么您将无法自定义UISearchBar
背景颜色。
如果您将searchBarStyle
设置为UISearchBarStyleMinimal
那么它会弄乱UISearchBar
的颜色,正如@Rich Fox 所说。
所以, [self.searchField setBackgroundImage:[[UIImage alloc]init]];
去除边框的解决方案。
使用示例更新:
UISearchBar *search = [[UISearchBar alloc] init];
search.tag = kTagSearchBar;
search.delegate = self;
search.tintColor = [UIColor redColor];
search.searchBarStyle = UISearchBarStyleMinimal;
search.frame = CGRectMake(0, 0, 320, 50);
search.placeholder = @"Search";
search.barTintColor = [UIColor blueColor];
search.translucent = NO;
search.opaque = NO;
search.showsCancelButton = NO;
[search setBackgroundImage:[[UIImage alloc] init]];
[self.view addSubview:search];
//customize textfield inside UISearchBar
@try {
for (id object in [[[search subviews] firstObject] subviews])
{
if (object && [object isKindOfClass:[UITextField class]])
{
UITextField *textFieldObject = (UITextField *)object;
textFieldObject.backgroundColor = [UIColor whiteColor];
textFieldObject.borderStyle = UITextBorderStyleLine;
textFieldObject.layer.borderColor = [UIColor blueColor].CGColor;
textFieldObject.layer.borderWidth = 1.0;
break;
}
}
}
@catch (NSException *exception) {
NSLog(@"Error while customizing UISearchBar");
}
@finally {
}
会给你:
不仅barTintColor
, backgroundImage
和backgroundColor
都没有为我做这件事,但把它们一起做对我barTintColor
:
self.searchBar.translucent = NO;
self.searchBar.barTintColor = [styleManager currentSearchBarTintColor];
self.searchBar.backgroundImage = [UIImage new];
self.searchBar.backgroundColor = [styleManager currentSearchBarTintColor];
好的。 有很多答案,但它们太复杂了。 我找到了这个解决方案:
斯威夫特 3 (4)
searchBar.setBackgroundImage(UIImage(), for: .top, barMetrics: .default)
searchBar.backgroundColor = .primary
.primary 在哪里
extension UIColor {
static var primary:UIColor {
return "#5163F4".color
}
}
self.searchBar.translucent = NO;
self.searchBar.opaque = NO;
if ([self.searchBar respondsToSelector:@selector(setSearchBarStyle:)]) {
self.searchBar.searchBarStyle = UISearchBarStyleMinimal;
}
// iOS 7 remove 1 px bottom border
if ([self.searchBar respondsToSelector:@selector(setBarTintColor:)]) {
self.searchBar.barTintColor = [UIColor clearColor];
}
self.searchBar.barStyle = UIBarStyleDefault;
// to remove the 1px bottom border iOS 5, 6
[self.searchBar setBackgroundImage:[UIImage imageWithColor:[UIColor clearColor] andSize:CGSizeMake(1.0f, 1.0f)]];
代码的顺序似乎很重要。 如果我在 searchBarStyle 之前设置 barStyle,它就不起作用。
Xcode 7.2 中的 Swift 2.1,这对我有用。
self.searchController.searchBar.backgroundImage = UIImage()
我的完整代码如下。
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
self.searchController.searchBar.sizeToFit()
tableView.sectionIndexBackgroundColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.backgroundColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.barTintColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.backgroundImage = UIImage()
definesPresentationContext = true
tableView.tableHeaderView = searchController.searchBar
- (void)createNavigationBar
{
_searchBar = [[UISearchBar alloc]init];
_searchBar.backgroundColor = [UIColor whiteColor];
_searchBar.placeholder = @"Search";
_searchBar.translatesAutoresizingMaskIntoConstraints = NO;
self.navigationItem.titleView = _searchBar;
NSDictionary *viewsDictionary = @{@"SearchBar":_searchBar};
NSArray *constraint_POS_V = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|-5-[SearchBar(30)]|"
options:0
metrics:nil
views:viewsDictionary];
NSArray *constraint_POS_H = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|-15-[SearchBar]-15-|"
options:0
metrics:nil
views:viewsDictionary];
[_searchBar.superview addConstraints:constraint_POS_V];
[_searchBar.superview addConstraints:constraint_POS_H];
}
