ios开发之--搜索框的使用（PYSearchViewController的使用）

最近需要开发搜索框，比较了以前的各个版本的搜索框，UISearchDisplayController和UISearchController的使用，以后再做记录，随着ios11的更新，一些控件发生了，改变，不过也不影响我们，这里我根据大神封装的PYSearchViewController，重新小小的封装了下，加了个自定义导航，效果图如下：

大神封装的已经很好了，具体代码如下：

在大神封装的类库里面的PYSearchViewController类的第251行，添加如下代码；

 //改变导航背景颜色
    [UINavigationBar appearance].barTintColor = MainColor;

和上面的那个方法，可以自己自定义导航栏的背景颜色，和字体的颜色！

 

分享一个自定义导航，没什么两点，只是做记录用：

        }
            break;
        default:
            break;
    }
}

-(void)clickLeftBtn:(UIButton *)sender
{
    if (self.delegate && [self.delegate respondsToSelector:@selector(leftBtnAction:)]) {
        [self.delegate leftBtnAction:sender];
    }
}

-(void)clickRightBtn:(UIButton *)sender
{
    if (self.delegate && [self.delegate respondsToSelector:@selector(rightBtnAction:)]) {
        [self.delegate rightBtnAction:sender];
    }
}


@end

具体调用：

1，声明代理

@interface ViewController ()<CustomNavigationBarDelegate>

2，引用

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.navigationController.navigationBarHidden = YES;
    
    CustomNavigationBar *nav = [[CustomNavigationBar alloc]initWithFrame:CGRectMake(0, 0, KscreenW, 64) withTitle:@"首页" withLeftBtnHidden:NO withRightBtn:NO];
    nav.delegate = self;
    nav.rightBtnType = BtnTypeSearch;
    [self.view addSubview:nav];
}

3，然后实现两个代理方法：

-(void)leftBtnAction:(id)sender
{
    
}

-(void)rightBtnAction:(id)sender
{

}

这样就可以了！不过就是我还没有晚上手势返回那个功能，有兴趣的可以研究下，也就一行代码的事！

 

下面就是搜索框的使用：

1，引入代理

@interface ViewController ()<PYSearchViewControllerDelegate>

2，调用PYSearchViewController

-(void)rightBtnAction:(id)sender
{
    // 1. 创建热门搜索
    NSArray *hotSeaches = @[@"Java", @"Python", @"Objective-C", @"Swift", @"C", @"C++", @"PHP", @"C#", @"Perl", @"Go", @"JavaScript", @"R", @"Ruby", @"MATLAB"];
    // 2. 创建控制器
    PYSearchViewController *searchViewController = [PYSearchViewController searchViewControllerWithHotSearches:hotSeaches searchBarPlaceholder:@"搜索" didSearchBlock:^(PYSearchViewController *searchViewController, UISearchBar *searchBar, NSString *searchText) {
        // 开始搜索执行以下代码
        // 如：跳转到指定控制器
        [searchViewController.navigationController pushViewController:[[PYTempViewController alloc] init] animated:YES];
    }];
    // 3. 设置风格
    //        searchViewController.hotSearchStyle = PYHotSearchStyleNormalTag; // 热门搜索风格根据选择
    searchViewController.searchHistoryStyle = PYHotSearchStyleDefault; // 搜索历史风格为default
    // 5. 跳转到搜索控制器
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:searchViewController];
    [self presentViewController:nav  animated:NO completion:nil];
}

3，在搜索结果控制器PYTempViewController里面，会出现一个问题，从这个页面返回的时候，PYSearchViewController页面的导航栏不见了，解决方法如下：

@interface PYTempViewController ()<CustomNavigationBarDelegate>
{
    CustomNavigationBar *customBar;;
}

@end

@implementation PYTempViewController

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [customBar removeFromSuperview];
    self.navigationController.navigationBarHidden = NO;
}

- (void)viewWillAppear:(BOOL)animated
{
    self.navigationController.navigationBarHidden = YES;
    
    customBar = [[CustomNavigationBar alloc]initWithFrame:CGRectMake(0, 0, KscreenW, 64) withTitle:@"搜索结果" withLeftBtnHidden:NO withRightBtn:YES];
    customBar.delegate = self;
    [self.view addSubview:customBar];
}

把上述两个方法添加到控制器里面即可！

这样一个搜索框就完成了！很美观，定制型也很高，感谢大神们的无私奉献！
