我想自定义搜索栏,我的意思是白盒子。我可以做吗?有关于此的一些文件吗?有没有办法隐藏白框,但不是字母。我可以至少让盒子变小吗?我的意思是减少身高
通过IOS 5.0你有机会使用
[[UISearchBar appearance] setSearchFieldBackgroundImage:[UIImage imageNamed:@"searchbar.png"]forState:UIControlStateNormal];
这是我正在寻找的解决方案:子类化UISearchBar,并覆盖方法layoutSubviews
- (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;
那里的尝试很少,包括子类UISearchBar,并且它是layoutSubviews
或drawLayer:
。在iOS 5之后,最好的方法是使用UIAppearance。
// 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];
使用以下代码透明搜索栏
// Set it to your UISearchBar appearance
[[UISearchBar appearance] setBackgroundColor:[UIColor clearColor]];
[[UISearchBar appearance] setBackgroundImage:backgroundImage];
[[UISearchBar appearance] setSearchFieldBackgroundImage:searchFieldImage
forState:UIControlStateNormal];
Swift中的一些例子
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)
(UITextField.appearance(whenContainedInInstancesOf:[UISearchBar.self]))。defaultFxtAttributes = [NSForegroundColorAttributeName:UIColor.white]
