検索ボックスをカスタマイズしたいのですが、白いボックスです。できますか?それについてのドキュメントはありますか?ホワイトボックスを非表示にする方法はありますが、文字は非表示にしません。少なくとも箱を小さくできますか?身長が低い
IOS 5.0を使用する機会があります
[[UISearchBar appearance] setSearchFieldBackgroundImage:[UIImage imageNamed:@"searchbar.png"]forState:UIControlStateNormal];
私が探していたソリューションは次のとおりです:UISearchBarのサブクラス化、およびメソッドlayoutSubviewsの上書き
- (void)layoutSubviews {
UITextField *searchField;
NSUInteger numViews = [self.subviews count];
for(int i = 0; i < numViews; i++) {
if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) { //conform?
searchField = [self.subviews objectAtIndex:i];
}
}
if(!(searchField == nil)) {
searchField.textColor = [UIColor whiteColor];
[searchField setBackground: [UIImage imageNamed:@"buscador.png"] ];
[searchField setBorderStyle:UITextBorderStyleNone];
}
[super layoutSubviews];
}
// Search Bar Customization
// Background Image
[self.searchDisplayController.searchBar setBackgroundImage:[[UIImage alloc]init]];
// Backgroud Color
[self.searchDisplayController.searchBar setBackgroundColor:[UIColor redColor]];
// Search Bar Cancel Button Color
[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor whiteColor]];
// set Search Bar Search icon
[self.searchDisplayController.searchBar setImage:[UIImage imageNamed:@"search_ico.png"]
forSearchBarIcon:UISearchBarIconSearch
state:UIControlStateNormal];
// set Search Bar textfield background image
[[UISearchBar appearance] setSearchFieldBackgroundImage:[UIImage imageNamed:@"search_box.png"]
forState:UIControlStateNormal];
// set Search Bar texfield corder radius
UITextField *txfSearchField = [self.searchDisplayController.searchBar valueForKey:@"_searchField"];
txfSearchField.layer.cornerRadius = 10.8f;
Swiftのいくつかの例
UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).defaultTextAttributes = [NSForegroundColorAttributeName : UIColor.whiteColor()]
UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).attributedPlaceholder = NSAttributedString(string: "", attributes: [NSForegroundColorAttributeName : UIColor.whiteColor()])
UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).tintColor = UIColor.whiteColor()
UISearchBar.appearance().setImage(UIImage(named: "searchBarSearchIcon"), forSearchBarIcon: UISearchBarIcon.Search, state: UIControlState.Normal)
UISearchBar.appearance().setImage(UIImage(), forSearchBarIcon: UISearchBarIcon.Clear, state: UIControlState.Normal)
検索バーを透過するには以下のコードを使用
// Set it to your UISearchBar appearance
[[UISearchBar appearance] setBackgroundColor:[UIColor clearColor]];
[[UISearchBar appearance] setBackgroundImage:backgroundImage];
[[UISearchBar appearance] setSearchFieldBackgroundImage:searchFieldImage
forState:UIControlStateNormal];
サブクラスUISearchBarを含むいくつかの試みがあり、それをlayoutSubviews
またはdrawLayer:
。 iOS 5以降では、UIAppearanceを使用するのが最良の方法です。
// Configure your images
UIImage *backgroundImage = [UIImage imageNamed:@"searchbar"];
UIImage *searchFieldImage = [[UIImage imageNamed:@"searchfield"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
// Set it to your UISearchBar appearance
[[UISearchBar appearance] setBackgroundImage:backgroundImage];
[[UISearchBar appearance] setSearchFieldBackgroundImage:searchFieldImage forState:UIControlStateNormal];
(UITextField.appearance(whenContainedInInstancesOf:[UISearchBar.self])).defaultTextAttributes = [NSForegroundColorAttributeName:UIColor.white]
