前言：简单版可查看 模糊搜索 1 博客
一、申明相关属性和代理
<UITableViewDelegate,UITableViewDataSource,UIGestureRecognizerDelegate,UISearchBarDelegate>
/// tableView 搜索页
@property (nonatomic , strong) UIView *tableBGView;
@property (nonatomic , strong) UITableView *tableSearchView;
//数据源
@property (nonatomic , strong) NSMutableArray *dataList;
@property (nonatomic , strong) NSMutableArray *searchList;
@property (nonatomic , copy) NSString *inputString;
**
二、创建导航栏视图 ，MSUHomeNavView**
1.MSUHomeNavView.h 中的代码
/// 返回按钮
@property (nonatomic , strong) UIButton *backArrowBtn;
/// 搜索框按钮
@property (nonatomic , strong) UISearchBar *search;
2.MSUHomeNavView.m 中的代码
- (instancetype)initWithFrame:(CGRect)frame showNavWithNumber:(NSInteger)number
{
if (self = [super initWithFrame:frame]) {
switch (number) {
case 58:
{
/// 确认订单页面
[self createbackNavViewWithTyper:number];
}
break;
default:
break;
}
}
return self;
}
- (void)createbackNavViewWithTyper:(NSInteger)typer{
/// 取消按钮
self.backArrowBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[self addSubview:_backArrowBtn];
[_backArrowBtn setTitle:@"取消" forState:UIControlStateNormal];
_backArrowBtn.titleLabel.font = [UIFont systemFontOfSize:14];
[_backArrowBtn setTitleColor:HEXCOLOR(0xffffff) forState:UIControlStateNormal];
[_backArrowBtn makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(self.top).offset(0);
make.left.equalTo(self.left).offset(14);
make.width.equalTo(30);
make.height.equalTo(40);
}];
/// 搜索框
// self.search = [[UISearchBar alloc]initWithFrame:CGRectMake(40, 6, WIDTH-40-14, 28)];
// _search.placeholder = @"搜索感兴趣的内容";
// _search.searchBarStyle = UISearchBarStyleMinimal;
// _search.backgroundImage = [self imageWithColor:WHITECOLOR size:_search.bounds.size];
// [self addSubview:_search];
self.search = [[UISearchBar alloc]initWithFrame:CGRectMake(48, 3, WIDTH-40-14, 34)];
_search.placeholder = @"搜索您的小伙伴";
_search.backgroundImage = [self imageWithColor:WHITECOLOR size:_search.bounds.size];
_search.layer.borderColor = NavColor.CGColor;
_search.layer.borderWidth = 2;
_search.layer.cornerRadius = 7;
_search.clipsToBounds = YES;
[self addSubview:_search];
}
三、控制器中代码
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.nav = [[MSUHomeNavView alloc] initWithFrame:NavRect showNavWithNumber:numer];
[self.view addSubview:_nav];
_nav.search.delegate = self;
[self createTableView];
}
/* 搜索列表视图 */
- (void)createTableView{
self.tableBGView = [[UIView alloc] initWithFrame:CGRectMake(0, 60, WIDTH, HEIGHT-60)];
_tableBGView.backgroundColor = HEXCOLOR(0xf4f4f4);
_tableBGView.hidden = YES;
[self.view addSubview:_tableBGView];
// 列表初始化
self.tableSearchView = [[UITableView alloc] initWithFrame:CGRectMake(0, 10,WIDTH ,HEIGHT-60-10) style:UITableViewStylePlain];
_tableSearchView.delegate = self;
_tableSearchView.dataSource = self;
_tableSearchView.separatorStyle = UITableViewCellSelectionStyleNone;
// _tableView.bounces = NO;
_tableSearchView.showsVerticalScrollIndicator = NO;
_tableSearchView.rowHeight = 36;
[_tableBGView addSubview:_tableSearchView];
}
