在开发过程中,有时候系统给的searchBar和项目的风格不相同,有时候需要圆弧边角的searchBar,如图:

现在分享他的实现。
方法一:用系统自带的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]; //设置边框为白色
searchBar.placeholder = @"请输入关键词来查找房源";
[self.view addSubview:searchBar];

方法二:用UITextField改装成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 = @"请输入城市名称或首字母查询";
_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];

第二个方法实现的界面如图:

把绿色改成clearColor后:

@"citySelectbg":
