#高德地图 高德地图相关位置搜索有两种方法。 ##1.webAPI (建议使用，返回值中就包含了 address 和 location, 若使用客户端api.则返回的plceID,需再进行一次lookup请求才能得到location.）

返回的内容有：具体名称 和经纬度坐标， placeID（通过id可以确定某个坐标，这儿已经返回其坐标了所以不使用）。
使用注意点：
NSString *apiStr = @"AIzaSyBlW3RlTzQlYHRnxv8j5iGt5RkJBPUvJ-g"; //API For Web 此处是你所申请的APIKey， API for web 和 API for iOS是不一样的，既然用的是web接口就要用 API for web！
##iOS手机端API

[placeArr addObject:placeModel];
}
searchResult(YES,placeArr);
}else {
NSLog(@"Error-------%@",[error localizedDescription]);
searchResult(NO,nil);
}
}];
}
//根据PlaceID获取坐标经纬度。
+ (void)gooleMapLookUpPlaceID:(NSString *)placeID lookupRsult:(LookUpResult) lookUpResult {
[GMSPlacesClient provideAPIKey:@"AIzaSyD3NJirvXWjBsVo8SPzOOqRW0F_EDydex0"];

NSLog(@"Result '%f-----%f' with placeID %@", result.coordinate.latitude,result.coordinate.longitude, result.placeID);
DVGmapPlaceModel *placeModel = [[DVGmapPlaceModel alloc]init];
placeModel.placeID = result.placeID;
placeModel.location = result.coordinate;
lookUpResult(YES,placeModel);
}else {
lookUpResult(NO,nil);
}
}];
}
使用注意点：
1.在调用autocompleteQuery:SearchString方法之前必须调用：[GMSPlacesClient provideAPIKey:@"AIzaSyD3NJirvXWjBsVo8SPzOOqRW0F_EDydex0"]; //API For iOS方法，否者会报错：
** Error-------The operation couldn’t be completed. An internal error occurred in the Places API library. If you believe this error represents a bug, please file a report using the instructions on our community and support page (https://developers.google.com/places/support).**
(笔者第一次做的时候在这儿卡了很久）；
2.再次强调 API for iOS 与 API for web 不是同一个。
