OC 简单的高德地图使用

1.使用pod的方法导入高德SDK

	pod 'AMap2DMap-NO-IDFA'#2D高德地图
    pod 'AMapSearch-NO-IDFA'#高德地图搜索
    pod 'AMapLocation-NO-IDFA'#高德地图定位

pod install

2.在AppDelegate.m文件中开启地图服务

/**配置高德地图*/
    //配置HTTPS可用
    [AMapServices sharedServices].enableHTTPS = YES;
    //配置高德地图key
    [AMapServices sharedServices].apiKey = @"高德地图key";

3.创建一个控制器实现简单的地图运用：

#import "AMapViewController.h"

@interface AMapViewController ()<MAMapViewDelegate,AMapSearchDelegate,UITextFieldDelegate,UITableViewDelegate,UITableViewDataSource>
@property (nonatomic, strong)MAMapView *mapView;
@property (nonatomic, strong)AMapSearchAPI *search;

@property (nonatomic, strong)UITextField *searchT;
@property (nonatomic, strong)UITableView *tab;
@property (nonatomic, strong)NSArray *results;
@end

@implementation AMapViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.mapView = [[MAMapView alloc]initWithFrame:CGRectMake(0, 0, UI_SCREEN_WIDTH, UI_SCREEN_HEIGHT / 2)];
    self.mapView.mapType = MAMapTypeStandard;
    [self.view addSubview:self.mapView];
    //比例尺不显示
    self.mapView.showsScale = NO;
    //指南针不显示
    self.mapView.showsCompass = NO;
    //代理
    self.mapView.delegate = self;
    
    [self showUserLocation];
    [self addPointAnnotationWithCoordinate:CLLocationCoordinate2DMake(30.28,120.15) Title:@"系统大头针" subTitle:@"系统大头针描述"];
    //初始化搜索API
    self.search = [[AMapSearchAPI alloc]init];
    self.search.delegate = self;
    //设置搜索
    self.searchT = [[UITextField alloc]initWithFrame:CGRectMake(0, self.mapView.maxY - HeightForNagivationBarAndStatusBar, UI_SCREEN_WIDTH, 40)];
    self.searchT.backgroundColor = [UIColor whiteColor];
    self.searchT.placeholder = @"请输入搜索内容";
    self.searchT.delegate = self;
    [self.view addSubview:self.searchT];
    //搜索结果列表
    self.tab = [[UITableView alloc]initWithFrame:CGRectMake(0, self.searchT.maxY, UI_SCREEN_WIDTH, UI_SCREEN_HEIGHT - HeightForNagivationBarAndStatusBar - HOME_INDICATOR_HEIGHT - self.searchT.maxY)];
    self.tab.delegate = self;
    self.tab.dataSource = self;
    [self.view addSubview:self.tab];
    self.results = [NSArray array];
    
}
