最近公司需要做範圍內打卡的功能，所以研究了下高德地圖的SDK，首先註冊申請key就不多講了，百度有很詳細的資料，下面主要記錄下實現方法。demo地址在最下方：下載後自行更新cocoapod檔案下載依賴即可執行

包含功能1、定位 2、逆地理位置3、設定範圍打卡 4、自定義指標選定位置

我用的是pod管理工程，這是所有的sdk檔案

pod 'AFNetworking'

pod 'FMDB'

pod 'YYKit'

pod 'AMap3DMap'

pod 'AMapSearch'

更新下載好cocoapod依賴之後在appdelegate裡面設定關鍵key

// 配置高德地圖

[AMapServices

在這裡我們用的是MAMapView，而不是用的manager網上有很多方法都是用的manager，我感覺既然有地圖試圖為什麼不直接用呢？

// 設定打卡地點經緯度

@property (nonatomic,strong)NSString *localLongitude;

@property (nonatomic,strong)NSString *localLatitude;

// 高德地圖

@property (nonatomic

//全域性的大頭針

@property(nonatomic,strong)MAPointAnnotation *pointAnnotation;

// 定位當前位置的經緯度

@property (nonatomic,strong)NSString *userLongitude;

@property (nonatomic,strong)NSString *userLatitude;

在viewdidappear裡面家在資訊

// 進入介面就以定位點為地圖中心

[self.mapViewsetCenterCoordinate:CLLocationCoordinate2DMake

// 將繪製的圖形新增到地圖上

[self.mapViewaddOverlays:self.circles];

在viewdidload載入地圖資訊

// https配置

[AMapServicessharedServices].enableHTTPS =YES;

// 初始化地圖

self.mapView = [[MAMapViewalloc]initWithFrame:CGRectMake(0,NAVIGATIONBAR_HEIGHT,SCREEN_WIDTH,SCREEN_HEIGHT -NAVIGATIONBAR_HEIGHT)];

self.mapView.delegate =self;

// 顯示定位小藍點

self.mapView.showsUserLocation =YES;

self.mapView.showsCompass =NO;

//建立手勢物件

UILongPressGestureRecognizer *tap =[[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(longPress:)];

[_mapViewaddGestureRecognizer:tap];

//全域性的大頭針

_pointAnnotation = [[MAPointAnnotationalloc]init];

_pointAnnotation.coordinate =CLLocationCoordinate2DMake([self.userLatitudedoubleValue], [self.userLongitudedoubleValue]);

[_mapViewaddAnnotation:_pointAnnotation];

[_mapViewsetCenterCoordinate:CLLocationCoordinate2DMake([self.userLatitudedoubleValue], [self.userLongitudedoubleValue])animated:YES];

// 追蹤使用者的location更新

self.mapView.userTrackingMode =MAUserTrackingModeFollow;

// 放大等級

[self.mapViewsetZoomLevel:16animated:YES];

[self.viewaddSubview:self.mapView];

下面是設定代理方法，動態開啟需要選中一個點作為開啟地點，我們新增一個長按手勢獲取動態位置，然後作為打卡點，通過獲得的經緯度逆地理位置資訊顯示在title上，然後與定位獲得的經緯度比較判定是否滿足打卡範圍。這樣就完整實現了定位打卡的功能。

下面是長按手勢方法

//自定義大頭針我這裡只是把大頭針變成一張自定義的圖片

- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation

{

if ([annotationisKindOfClass:[MAPointAnnotationclass]])

{

staticNSString *reuseIndetifier =@"annotationReuseIndetifier";

MAAnnotationView *annotationView = (MAAnnotationView *)[mapViewdequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];

if (annotationView ==nil)

{

annotationView = [[MAAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:reuseIndetifier];

}

annotationView.image = [UIImageimageNamed:@"locationPoint_select"];

//設定中心點偏移，使得標註底部中間點成為經緯度對應點

annotationView.centerOffset =CGPointMake(0, -18);

return annotationView;

}

returnnil;

}

- (void)longPress:(UIGestureRecognizer*)gestureRecognizer{

//if (gestureRecognizer.state == UIGestureRecognizerStateEnded){

//return;

//}

[_mapViewremoveAnnotation:_pointAnnotation];

//座標轉換

CGPoint touchPoint = [gestureRecognizer locationInView:_mapView];

CLLocationCoordinate2D touchMapCoordinate =

[_mapViewconvertPoint:touchPointtoCoordinateFromView:_mapView];

_pointAnnotation.coordinate = touchMapCoordinate;

//_pointAnnotation.title = @"設定名字";

[_mapViewaddAnnotation:_pointAnnotation];

[selfsetLocationWithLatitude:touchMapCoordinate.latitudeAndLongitude:touchMapCoordinate.longitude];

}

- (void)setLocationWithLatitude:(CLLocationDegrees)latitude AndLongitude:(CLLocationDegrees)longitude{

NSString *latitudeStr = [NSStringstringWithFormat:@"%f",latitude];

NSString *longitudeStr = [NSStringstringWithFormat:@"%f",longitude];

NSLog(@"自己加的%@%@",latitudeStr,longitudeStr);

//反編碼經緯度---->位置資訊

CLLocation *location=[[CLLocationalloc]initWithLatitude:latitudelongitude:longitude];

CLGeocoder *geocoder=[[CLGeocoderalloc]init];

[geocoder reverseGeocodeLocation:locationcompletionHandler:^(NSArray *placemarks,NSError *error) {

if (error) {

NSLog(@"反編碼失敗:%@",error);

[selfpresentAlertControllerWithTitle:@"提示"message:[NSStringstringWithFormat:@"該網點經緯度資訊有誤，請重新標註"]cancelTitle:@"好的"];

}else{

self.localLatitude = latitudeStr;

self.localLongitude = longitudeStr;

// 重新繪製打卡範圍

[selfsetAddress];

//NSLog(@"反編碼成功:%@",placemarks);

CLPlacemark *placemark=[placemarkslastObject];

//NSLog(@"%@",placemark.addressDictionary[@"FormattedAddressLines"]);

NSDictionary *addressDic=placemark.addressDictionary;

NSString *state=[addressDicobjectForKey:@"State"];

NSString *city=[addressDicobjectForKey:@"City"];

NSString *subLocality=[addressDicobjectForKey:@"SubLocality"];

NSString *street=[addressDicobjectForKey:@"Street"];

NSString *Thoroughfare=[addressDicobjectForKey:@"Thoroughfare"];

NSString *strLocation;

if (street.length ==0 || street ==NULL || [streetisEqualToString:@"(null)"]) {

strLocation= [NSStringstringWithFormat:@"%@",subLocality];

}elseif (Thoroughfare.length ==0 || Thoroughfare == NULL || [ThoroughfareisEqualToString:@"(null)"]||([streetisEqualToString:Thoroughfare])){

strLocation= [NSStringstringWithFormat:@"%@%@",subLocality,street];

}else{

strLocation= [NSStringstringWithFormat:@"%@%@%@",subLocality,street,Thoroughfare];

}

NSLog(@"%@%@%@",state,city,strLocation);

self.title = strLocation;

}

}];

}

其他功能參考一下高德地圖，可是實現長按出現選定位置資訊，反編譯出地理資訊，名稱等。
