iOS UISearchBar搜索框

 

 

#import "ViewController.h"

@interface ViewController ()<UISearchBarDelegate>
/** 搜索框 */
@property (nonatomic, weak) UISearchBar *searchBar;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 64, [UIScreen mainScreen].bounds.size.width, 40)];
    //设置提示文字
   self.searchBar.placeholder = @"搜索";
    //设置边框背景图片
   self. searchBar.backgroundImage = [UIImage imageNamed:@"searchBar_BG"];
    //设置代理
    self.searchBar.delegate = self;
    //添加到视图
    [self.view addSubview:self.searchBar];
}


@end

就可以简单运行UISearchBar了

正式项目中往往要做成懒加载样式
