在開發(fā)過程中，有時(shí)候系統(tǒng)給的searchBar和項(xiàng)目的風(fēng)格不相同举反，有時(shí)候需要圓弧邊角的searchBar懊直，如圖：

現(xiàn)在分享他的實(shí)現(xiàn)。
方法一：用系統(tǒng)自帶的searchBar：
UISearchBar *searchBar = [[UISearchBar alloc] init];
searchBar.delegate = self;
searchBar.frame = CGRectMake(10, 28, SCREEN_WIDTH - 20, 32);
searchBar.backgroundColor = [UIColor redColor];
searchBar.layer.cornerRadius = 16;
searchBar.layer.masksToBounds = YES;
[searchBar.layer setBorderWidth:8];
[searchBar.layer setBorderColor:[UIColor whiteColor].CGColor]; //設(shè)置邊框?yàn)榘咨? searchBar.placeholder = @"請輸入關(guān)鍵詞來查找房源";
[self.view addSubview:searchBar];
方法二：用UITextField改裝成searchBar：
UIView *searchView = [[UIView alloc] initWithFrame:CGRectMake(0, 64, self.view.frame.size.width, 40*(self.view.frame.size.height/568))];
searchView.backgroundColor = [UIColor clearColor];
UIImageView *searchBg = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"citySelectbg"]];
searchBg.frame = CGRectMake(0, 0, searchView.frame.size.width, searchView.frame.size.height);
[searchView addSubview:searchBg];
//搜索框
_searchText = [[UITextField alloc]initWithFrame:CGRectMake(30*(self.view.frame.size.width/320), 0, self.view.frame.size.width-30, searchView.frame.size.height)];
_searchText.backgroundColor = [UIColor greenColor];
_searchText.font = [UIFont systemFontOfSize:13];
_searchText.placeholder = @"請輸入城市名稱或首字母查詢";
_searchText.returnKeyType = UIReturnKeySearch;
_searchText.textColor = [UIColor colorWithRed:58/255.0 green:58/255.0 blue:58/255.0 alpha:1];
_searchText.delegate = self;
[_searchText addTarget:self action:@selector(textChange:) forControlEvents:UIControlEventEditingChanged];
[searchView addSubview:_searchText];
[self.view addSubview:searchView];
第二個(gè)方法實(shí)現(xiàn)的界面如圖：

把綠色改成clearColor后：

看上去就像是一個(gè)searchBar火鼻。
@"citySelectbg"：
