iOS 调用地图导航

在IOS6.0系统后，兼容iOS5.0与iOS6.0地图导航，需要分两个步骤

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)//用来获取手机的系统，判断系统是多少

    CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
    CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
    
    if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下，调用google map
        
        NSString *urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude];
        //        @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude
        urlString =  [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        NSURL *aURL = [NSURL URLWithString:urlString];
        [[UIApplication sharedApplication] openURL:aURL];
    } else { // 直接调用ios自己带的apple map
        
        MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
        MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil]];
        toLocation.name = @"to name";
        
        [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
                       launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
        
    }

　　

如果不想使用苹果自带的地图的话，也可以使用第三方的地图，如百度、Google　Maps、高德等

使用前，先判断设备上是否已安装应用

百度地图：

if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"baidumap://map/"]])

参考

高德地图：

if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"iosamap://"]])

参考

Google Maps：

if ([[UIApplicationsharedApplication]canOpenURL:[NSURLURLWithString:@"comgooglemaps://"]])

参考

示例代码

- (void)availableMapsApps {
    [self.availableMaps removeAllObjects];
    
    CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
    CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
    NSString *toName = @"to name";
    
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]){
        NSString *urlString = [NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:%@&mode=transit",
                               startCoor.latitude, startCoor.longitude, endCoor.latitude, endCoor.longitude, toName];
        
        NSDictionary *dic = @{@"name": @"百度地图",
                              @"url": urlString};
        [self.availableMaps addObject:dic];
    }
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSString *urlString = [NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=applicationScheme&poiname=fangheng&poiid=BGVIS&lat=%f&lon=%f&dev=0&style=3",
                               @"云华时代", endCoor.latitude, endCoor.longitude];
        
        NSDictionary *dic = @{@"name": @"高德地图",
                              @"url": urlString};
        [self.availableMaps addObject:dic];
    }
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
        NSString *urlString = [NSString stringWithFormat:@"comgooglemaps://?saddr=&daddr=%f,%f¢er=%f,%f&directionsmode=transit", endCoor.latitude, endCoor.longitude, startCoor.latitude, startCoor.longitude];
        
        NSDictionary *dic = @{@"name": @"Google Maps",
                              @"url": urlString};
        [self.availableMaps addObject:dic];
    }
}

　　显示一个ActionSheet

[self availableMapsApps];
    UIActionSheet *action = [[UIActionSheet alloc] init];
    
    [action addButtonWithTitle:@"使用系统自带地图导航"];
    for (NSDictionary *dic in self.availableMaps) {
        [action addButtonWithTitle:[NSString stringWithFormat:@"使用%@导航", dic[@"name"]]];
    }
    [action addButtonWithTitle:@"取消"];
    action.cancelButtonIndex = self.availableMaps.count + 1;
    action.delegate = self;
    [action showInView:self.view];

　　实现delegate

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        CLLocationCoordinate2D startCoor = self.mapView.userLocation.location.coordinate;
        CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude+0.01, startCoor.longitude+0.01);
        
        if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下，调用google map
            
            NSString *urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude];
            //        @"http://maps.apple.com/?saddr=%f,%f&daddr=%f,%f",startCoor.latitude,startCoor.longitude,endCoor.latitude,endCoor.longitude
            urlString =  [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            NSURL *aURL = [NSURL URLWithString:urlString];
            [[UIApplication sharedApplication] openURL:aURL];
        } else{// 直接调用ios自己带的apple map
