前言:最近因为项目需求需要做国际版本,需要把国内的高德地图换成谷歌地图GoogleMaps 。网上一查,关于GoogleMaps的坑太多,资料太少,在此献上最近忙活的成果,提供集成GoogleMaps的一些方法。
Google Maps接入 必须翻墙
参考援助
集成很简单 跟着上面的网址一步一步做就可以
最后PS:plist 文件里面的设置
在 iOS9 中需要配置 plist 文件
<key>LSApplicationQueriesSchemes</key>
<array>
<string>googlechromes</string>
<string>comgooglemaps</string>
</array>
一开始一直崩溃
后来解决啦 没有添加谷歌地图的key
定位我用的系统的定位 CLLocationManager 这就不用多说啦把。(在国内有偏差,国外是正常的,因为火星坐标 (GCJ-02))
ps 也可以使用KVO定位
- (void)viewDidLoad {
//...
[self.mapView addObserver:self forKeyPath:"myLocation" options:0 context:nil];
}
- (void)dealloc {
[_mapView removeObserver:self forKeyPath:@"myLocation"];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if([keyPath isEqualToString:@"myLocation"]) {
CLLocation *l = [object myLocation];
//...
}
}
下面开始粘代码
引入头文件
#import <GoogleMaps/GoogleMaps.h>
static NSString *const kAPIKey = @"你自己的key";
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// [GMSServices provideAPIKey:@"AIzaSyAleSTvh3HFWKnUFgJStps-nxw3opQARaw"];
if (kAPIKey.length == 0) {
// Blow up if APIKey has not yet been set.
NSString *bundleId = [[NSBundle mainBundle] bundleIdentifier];
NSString *format = @"Configure APIKey inside SDKDemoAPIKey.h for your "
@"bundle `%@`, see README.GoogleMapsDemos for more information";
@throw [NSException exceptionWithName:@"DemoAppDelegate"
reason:[NSString stringWithFormat:format, bundleId]
userInfo:nil];
}
[GMSServices provideAPIKey:kAPIKey];
return YES;
}
//地图
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.868
longitude:151.2086
zoom:12];
_mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
_mapView.delegate =self;
_mapView.settings.compassButton = YES;
_mapView.settings.myLocationButton = YES;
//大头针
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
marker.title = @"Sydney";
marker.snippet = @"Australia";
marker.map = _mapView;
// 划线
GMSMutablePath *path = [GMSMutablePath path];
[path addCoordinate:CLLocationCoordinate2DMake(@(-33.860).doubleValue,@(151.208).doubleValue)];
[path addCoordinate:CLLocationCoordinate2DMake(@(-33.860).doubleValue,@(151.008).doubleValue)];
[path addCoordinate:CLLocationCoordinate2DMake(@(-33.860).doubleValue,@(150.508).doubleValue)];
[path addCoordinate:CLLocationCoordinate2DMake(@(-32.860).doubleValue,@(150.208).doubleValue)];
GMSPolyline *rectangle = [GMSPolyline polylineWithPath:path];
rectangle.strokeWidth = 2.f;
rectangle.map = _mapView;
self.view = _mapView;
下面说几个代理方法 有些事百度的有些是自己试的,不对的话希望指出来。谢谢
/地图代理
- (void)mapView:(GMSMapView *)mapView willMove:(BOOL)gesture{
NSLog(@"gesture === %@",[NSNumber numberWithBool:gesture]);
}
//这个代理方法主要作用就是当你移动镜头也就是拖动地推的时候,就会调用这个方法
- (void)mapView:(GMSMapView *)mapView didChangeCameraPosition:(GMSCameraPosition *)position{
NSLog(@"didChangeCameraPosition ==== %@",position);
}
//这个代理方法你就可以拿到屏幕中心点的位置的经纬度了,这是一个很简单的方法。当然,这个方法是有缺陷的,就是我们只能拿到经纬度,却拿不到经纬度所对应的地址之类的一些信息。
- (void)mapView:(GMSMapView *)mapView idleAtCameraPosition:(GMSCameraPosition *)position{
NSLog(@"idleAtCameraPosition ==== %@",position);
NSLog(@"target ==== %f,%f",position.target.latitude,position.target.longitude);
//这个方法是清理掉地图上所有的东西,包括什么大头针之类的,这里的目的是为了使地图上只有一个大头针
// [_mapView clear];
// _marker = [[GMSMarker alloc] init];
// _marker.position = CLLocationCoordinate2DMake(position.target.latitude, position.target.longitude);
// _marker.icon = [UIImage imageNamed:@"bigLoc"];
// _marker.map = _mapView;
}
//这个三个代理方法要怎么解释我就真不知道了,大家伙可以试试
//开始
- (void)mapViewDidStartTileRendering:(GMSMapView *)mapView{
// NSLog(@"mapViewDidStartTileRendering ==== %@",mapView);
}
//滑动
- (void)mapViewDidFinishTileRendering:(GMSMapView *)mapView{
// NSLog(@"mapViewDidFinishTileRendering ==== %@",mapView);
}
//暂停
- (void)mapViewSnapshotReady:(GMSMapView *)mapView{
// NSLog(@"mapViewSnapshotReady ==== %@",mapView);
}
