iOS-trip-search

类似滴滴主界面的搜索功能

前述

• 工程基于iOS 地图和搜索SDK实现
• 高德官网申请Key.
• 阅读开发指南.
• 运行demo请先执行pod install --repo-update 安装依赖库，完成后打开.xcworkspace 文件

核心难点

Objective-C

// 显示搜索&城市列表
- (void)showCityListViewOnlyCity:(BOOL)onlyCity
{
    [self.navigationController setNavigationBarHidden:YES animated:YES];
    [self.cityListView reset];
    self.searchResultView.poiArray = nil;
    
    self.searchBar.doubleSearchModeEnable = !onlyCity;
    self.searchBar.seachCity = [MyCityManager sharedInstance].currentCity;
    
    self.searchResultView.hidden = onlyCity;
    if (!onlyCity) {
        [self updateSearchResultForCurrentCity];
    }
    
    [self.searchBar reset];
    [self.searchBar becomeFirstResponder];
    
    [UIView animateWithDuration:0.3 animations:^{
        self.listContainerView.frame = CGRectMake(kTableViewMargin, kTableViewMargin + kNaviBarHeight, self.listContainerView.frame.size.width, self.listContainerView.frame.size.height);
        
        self.searchBar.frame = CGRectMake(0, 0, self.view.bounds.size.width, kNaviBarHeight);
    }];
}

// 隐藏搜索&城市列表
- (void)hideCityListView
{
    [self.navigationController setNavigationBarHidden:NO animated:YES];
    [self.searchBar resignFirstResponder];
    self.searchBar.currentSearchKeywords = nil;
    
    [UIView animateWithDuration:0.3 animations:^{
        self.listContainerView.frame = CGRectMake(kTableViewMargin, CGRectGetMaxY(self.view.bounds), self.listContainerView.frame.size.width, self.listContainerView.frame.size.height);
        
        self.searchBar.frame = CGRectMake(0, -kNaviBarHeight, self.view.bounds.size.width, kNaviBarHeight);
    }];
}

//选择城市
- (void)cityListView:(MyCityListView *)listView didCitySelected:(MyCity *)city
{
    MyCity *oldCity = [MyCityManager sharedInstance].currentCity;
    
    //单独改变当前城市
    if (!self.searchBar.doubleSearchModeEnable) {
        
        //单独改变城市时修改当前城市
        [self updateCurrentCity:city];

            self.locationView.endPOI = nil;
            self.locationView.startPOI = nil;
            // remove
            [self.mapView removeAnnotation:self.startAnnotation];
            [self.mapView removeAnnotation:self.endAnnotation];
            
        }
        
        //如果当前城市是定位城市直接进行当前定位的逆地理，否则进行地理编码获取城市位置。
        if ([city.name isEqualToString:[MyCityManager sharedInstance].locationCity.name]) {
            
            [self.mapView setCenterCoordinate:self.mapView.userLocation.location.coordinate animated:YES];
            
            [self searchReGeocodeWithLocation:[AMapGeoPoint locationWithLatitude:self.mapView.userLocation.location.coordinate.latitude longitude:self.mapView.userLocation.location.coordinate.longitude]];
        }
        else {
            [self searchGeocodeWithName:city.name];
        }
    }
    else {
        
        if (![oldCity.name isEqualToString:city.name]) {
            self.searchBar.seachCity = city; // 只修改搜索city
            [self updateSearchResultForCurrentCity];
        }
