基础代码

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 45.0f)];
        
    [self.view addSubview:search];
}

属性

搜索框风格 后两种已被禁用

typedef NS_ENUM(NSInteger, UIBarStyle) {
    UIBarStyleDefault         //白色搜索框，灰色背景
    UIBarStyleBlack           //黑色搜索框,
     
    UIBarStyleBlackOpaque      = 1, // 禁用. Use UIBarStyleBlack
    UIBarStyleBlackTranslucent = 2, // 禁用. Use UIBarStyleBlack and set the translucent property to YES
}

search.barStyle = UIBarStyleBlack;

search.barStyle = UIBarStyleDefault;

搜索框占位符

// 搜索的文本
@property(nullable,nonatomic,copy)   NSString *text;  
 // 搜索框顶部的提示信息 
@property(nullable,nonatomic,copy)   NSString *prompt;    
// 占位符，默认nil, 若有值则在输入文本后消失
@property(nullable,nonatomic,copy)   NSString *placeholder;

Demo

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.prompt = @"search‘s prompt";
    search.placeholder = @"search's placeholder";
    
    
    [self.view addSubview:search];
}

效果图

搜索框右边的按钮风格

//搜索框右侧是否显示图书按钮
@property(nonatomic)  BOOL   showsBookmarkButton __TVOS_PROHIBITED;   // default is NO
//搜索框右侧是否显示取消按钮
@property(nonatomic)  BOOL   showsCancelButton __TVOS_PROHIBITED;     // default is NO
//搜索框右侧是否显示搜索结果按钮
@property(nonatomic)  BOOL   showsSearchResultsButton NS_AVAILABLE_IOS(3_2) __TVOS_PROHIBITED; // default is NO
@property(nonatomic, getter=isSearchResultsButtonSelected) BOOL searchResultsButtonSelected NS_AVAILABLE_IOS(3_2) __TVOS_PROHIBITED;

search.showsBookmarkButton = YES; 效果

search.showsCancelButton = YES; 效果

search.showsSearchResultsButton = YES;

search.showsSearchResultsButton = YES; search.searchResultsButtonSelected = YES; 都要设置

搜索框 颜色、背景颜色

// //设置光标颜色
@property(null_resettable, nonatomic,strong) UIColor *tintColor;
//  //搜索框背景颜色
@property(nullable, nonatomic,strong) UIColor *barTintColor;

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.placeholder = @"search's placeholder";
    //设置光标颜色
    search.tintColor = [UIColor redColor];
    //搜索框背景颜色
    search.barTintColor = [UIColor greenColor];
    
    
    [self.view addSubview:search];
}

背景颜色和光标颜色改变

搜索框 样式

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.placeholder = @"search's placeholder";
    
    
    [self.view addSubview:search];
}

//搜索框样式
@property (nonatomic) UISearchBarStyle searchBarStyle;

typedef NS_ENUM(NSUInteger, UISearchBarStyle) {
    //默认样式和UISearchBarStyleProminent效果一样
    UISearchBarStyleDefault,    // currently UISearchBarStyleProminent
    UISearchBarStyleProminent,  // used my Mail, Messages and Contacts
    //没有背景
    UISearchBarStyleMinimal     // used by Calendar, Notes and Music
} 

search.searchBarStyle = UISearchBarStyleDefault; 效果

search.searchBarStyle = UISearchBarStyleProminent;

search.searchBarStyle = UISearchBarStyleMinimal; 没有背景

搜索框 附件选择按钮视图

//选择按钮试图的按钮标题
@property(nullable, nonatomic,copy) NSArray<NSString *>   *scopeButtonTitles ; 
//选中的按钮下标值 ，默认 0. 如果超出范围则忽略
@property(nonatomic) NSInteger  selectedScopeButtonIndex ;
//是否显示搜索栏的附件选择按钮视图
@property(nonatomic) BOOL     showsScopeBar;

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.placeholder = @"search's placeholder";
    
    search.showsScopeBar = YES;
    search.selectedScopeButtonIndex = 1;
    search.scopeButtonTitles = @[@"One",@"Two",@"Three"];
    
    
    [self.view addSubview:search];
}

搜索框背景图片、搜索框附属分栏条的背景颜色

@property(nullable, nonatomic,strong) UIImage *scopeBarBackgroundImage;

搜索框 背景图片和附属栏背景图片设置

// 搜索框背景图片
@property(nullable, nonatomic,strong) UIImage *backgroundImage;
// 搜索框附属分栏条的背景颜色
@property(nullable, nonatomic,strong) UIImage *scopeBarBackgroundImage;

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.placeholder = @"search's placeholder";
    
    search.showsScopeBar = YES;
    search.selectedScopeButtonIndex = 1;
    search.scopeButtonTitles = @[@"One",@"Two",@"Three"];
    
    UIImage *image = [UIImage imageNamed: @"icon"];
    search.backgroundImage = image;
    search.scopeBarBackgroundImage = [UIImage imageNamed:@"my_service"];
    
    
    [self.view addSubview:search];
}

背景图设置

搜索框 文本框的背景偏移量和文本偏移量

// 搜索框中文本框的背景偏移量
@property(nonatomic) UIOffset searchFieldBackgroundPositionAdjustment;
// 搜索框中文本框的文本偏移量
@property(nonatomic) UIOffset searchTextPositionAdjustment;

- (void)testSearchBar {
    UISearchBar *search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, HGSTATUS_FRAME_HEIGHT, HGSCREEN_WIDTH, 100.0f)];
    search.barStyle = UIBarStyleDefault;
    search.placeholder = @"search's placeholder";
    
    search.searchFieldBackgroundPositionAdjustment = UIOffsetMake(5, 3);
    search.searchTextPositionAdjustment = UIOffsetMake(10, 5);
    
    
    [self.view addSubview:search];
}

偏移量进行了修改
