一：定位权限
1.导入CoreLocation，MapKit库。
2.在需要弹出位置授权的界面导入头文件
import <CoreLocation/CoreLocation.h>
import <MapKit/MapKit.h>
3.info.plist文件添加3个授权
a. NSLocationWhenInUseUsageDescription （应用使用期间），
b. NSLocationAlwaysUsageDescription（始终允许），
c. NSLocationAlwaysAndWhenInUseUsageDescription（始终允许，iOS11新增）
在iOS11时，NSLocationAlwaysAndWhenInUseUsageDescription表示始终允许，NSLocationAlwaysUsageDescription在功能上被降级为为“应用使用期间”。
如果a,b两项添加到plist里，授权提示有2个选择项
如果a,b,c 全部添加到plist里，授权提示有3个选择项
4.跳转到地图界面前，进行位置权限判断，只有允许了定位才能跳转界面。
-(void)clickToMapVC{
//确定用户的位置服务是否启用,位置服务在设置中是否被禁用
BOOL enable =[CLLocationManager locationServicesEnabled];
NSInteger status =[CLLocationManager authorizationStatus];
if( !enable || status< 2){
//尚未授权位置权限
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8)
{
//系统位置授权弹窗
_locationManager =[[CLLocationManager alloc]init];
[_locationManager requestAlwaysAuthorization];
[_locationManager requestWhenInUseAuthorization];
}
}else{
if (status == kCLAuthorizationStatusDenied) {
//拒绝使用位置
UIAlertView *alterView = [[UIAlertView alloc] initWithTitle:nil message:@"地点功能需要开启位置授权" delegate:self cancelButtonTitle:@"暂不设置" otherButtonTitles:@"现在去设置", nil];
[alterView show];
}else{
//允许使用位置
MapLocationVC *mapVC =[[MapLocationVC alloc]init];
mapVC.fromComment =YES;
mapVC.delegate =self;
if ([self.delegate respondsToSelector:@selector(presentVC:)]) {
[self.delegate presentVC:mapVC];
}
}
}
}
二：打开第三方地图
//导航到目的地，endLocation为目的地经纬度
-(void)navThirdMapWithLocation:(CLLocationCoordinate2D)endLocation
NSMutableArray *mapsA = [NSMutableArray array];
//苹果原生地图方法和其他不一样
NSMutableDictionary *iosMapDic = [NSMutableDictionary dictionary];
iosMapDic[@"title"] = @"苹果地图";
iosMapDic[@"url"] = [NSString stringWithFormat:@"%f-%f",endLocation.latitude,endLocation.longitude];
[mapsA addObject:iosMapDic];
//高德地图
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
gaodeMapDic[@"title"] = @"高德地图";
NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",@"导航功能",@"nav123456",endLocation.latitude,endLocation.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
gaodeMapDic[@"url"] = urlString;
[mapsA addObject:gaodeMapDic];
}
//腾讯地图
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {

CLLocationCoordinate2D afterLocation =endLocation;

qqMapDic[@"url"] = urlString;
[mapsA addObject:qqMapDic];
}
//百度地图

baiduMapDic[@"title"] = @"百度地图";
//坐标转换

baiduMapDic[@"url"] = urlString;
[mapsA addObject:baiduMapDic];
}
//谷歌地图
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
NSMutableDictionary *googleMapDic = [NSMutableDictionary dictionary];

googleMapDic[@"url"] = urlString;
[mapsA addObject:googleMapDic];
}
//手机地图个数判断
if (mapsA.count > 0) {
//选择
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"使用导航" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
NSInteger index = mapsA.count;
for (int i = 0; i < index; i++) {
NSString *title = mapsA[i][@"title"];
NSString *urlString = mapsA[i][@"url"];
//苹果原生地图方法
if (i == 0) {
UIAlertAction *iosAntion = [UIAlertAction actionWithTitle:title style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
[self navAppleMap:urlString];
}];
[alertVC addAction:iosAntion];
continue;
}
UIAlertAction *action = [UIAlertAction actionWithTitle:title style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
}];
[alertVC addAction:action];
}
UIAlertAction *cancleAct = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
}];
[alertVC addAction:cancleAct];
if ([self.delegate respondsToSelector:@selector(presentVC:)]) {
[self.delegate presentVC:alertVC];
}
}else{
[MBProgressHUD showError:@"未检测到地图应用"];
}
}
//跳转到原生苹果地图
-
(void)navAppleMap:(NSString *)urlString{
NSArray *location = [urlString componentsSeparatedByString:@"-"];
CGFloat latitude = [location[0] floatValue];
CGFloat longitude = [location[1] floatValue];//终点坐标转换
CLLocationCoordinate2D afterLocation =CLLocationCoordinate2DMake(latitude, longitude);
//用户位置
MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
//终点位置
MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:afterLocation addressDictionary:nil] ];
//目的地名称
toLocation.name = @"地图上的点";//endLocation坐标对应的目的地名称
NSArray *items = @[currentLoc,toLocation];
NSDictionary *dic = @{
MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
MKLaunchOptionsMapTypeKey : [NSNumber numberWithInteger:MKMapTypeStandard],
MKLaunchOptionsShowsTrafficKey : @(YES)
