向前的地理编码不会给出正确的结果 [英] Forward geocoding doesnt give correct results
本文介绍了向前的地理编码不会给出正确的结果的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在某些情况下，我没有得到正确的转发地理编码结果。当我搜索某些地方或酒店时，会显示其他地方或地区的结果。我有以下代码。我研究了以下链接。
我们应该如何执行以下站点中给出的以下内容：
https://developers.google.com/places/webservice/autocomplete
包含Vict的地址请求以法语结果：
我执行了以下操作，但没有给出结果，因为我认为
- （CLLocationCoordinate2D）addressLocation {
NSError * error = nil;
// NSString * lookUpString = [NSString stringWithFormat：@http://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=true，SearchtextField ]。
// NSString * API_KEY = @AIzaSyB27SkGBzvEYKcxvZ5nmOVWvrA-6Xqf-7A;
NSString * API_KEY = @AIzaSyCHcqJcqZbP1XpU-WB4VfRct5hpdgqisSY;
NSString * lookUpString = [NSString stringWithFormat：@https://maps.googleapis.com/maps/api/geocode/json?address=%@®ion=np&key=%@，SearchtextField， API_KEY];
lookUpString = [lookUpString stringByReplacingOccurrencesOfString：@withString：@+];
NSData * jsonResponse = [NSData dataWithContentsOfURL：[NSURL URLWithString：lookUpString]];
NSDictionary * jsonDict = [NSJSONSerialization JSONObjectWithData：jsonResponse options：kNilOptions error：& error];
NSArray * locationArray = [[[[jsonDict valueForKey：@results] valueForKey：@geometry] valueForKey：@location];
NSString * statusString = [jsonDict valueForKey：@status];
if（[statusString isEqualToString：@OK]）
{
locationArray = [locationArray objectAtIndex：0];
Str_Latitude = [locationArray valueForKey：@lat];
Str_Longitude = [locationArray valueForKey：@lng];
NSLog（@LatitudeString：％@& LongitudeString：％@，Str_Latitude，Str_Longitude）;
/ * Google地点纬度经度* /
Arr_LatLong = @ [Str_Latitude，Str_Longitude];
[[NSUserDefaults standardUserDefaults] setValue：Str_Latitude forKey：@Str_Latitude];
[[NSUserDefaults standardUserDefaults] setValue：Str_Longitude forKey：@Str_Longitude];
[[NSUserDefaults standardUserDefaults] synchronize];
GogLatitude = [Str_Latitude doubleValue];
Goglongitude = [Str_Longitude doubleValue];
if（Bool_SearchField）{
[self getGoogleAddress];
Bool_SearchField = FALSE;
}其他{
}
}其他{
UIAlertView * alertview = [[UIAlertView alloc] initWithTitle： @找不到地址消息：@请确认你输入了一个有效的地址delegate：self cancelButtonTitle：@OKotherButtonTitles：nil];
[alertview show];
NSLog（@出错了，找不到地址）;
[self.tableView reloadData];
}
GogLocation.latitude = GogLatitude;
GogLocation.longitude = Goglongitude;
返回GogLocation;
}
当我在
maps.google.com它显示如下
但是，当我在我的搜索应用程序显示不同的位置，然后我搜索
解决方案
我已经完成了你在我的一个应用程序中所要求的内容，但url不同。 b
$ b
我发布每次在文本字段中输入内容时被调用的函数。
- （void）startAutocomplete {
NSString * baseUrl = [NSString stringWithFormat：@https：// maps。 googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key=AIzaSyDz3HAmNY8NsgIhtA8gtbH-QA08Lg9tej4&types=all，self.locationTextfield.text];
NSURL * url = [NSURL URLWithString：[baseUrl stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]];
NSLog（@Url：％@，url）;
NSURLRequest * request = [NSURLRequest requestWithURL：url];
[NSURLConnection sendAsynchronousRequest：request queue：[NSOperationQueue mainQueue] completionHandler：^（NSURLResponse * response，NSData * data，NSError * connectionError）{
if（connectionError！= nil ）{
[[[UIAlertView alloc] initWithTitle：nil message：connectionError.localizedDescription delegate：self cancelButtonTitle：@OKotherButtonTitles：nil] show];
} else {
NSError * error = nil;
self.searchResult = [NSJSONSerialization JSONObjectWithData：data options：0 error：& error];
//NSLog(@\"result:%@\",self.searchResult）;
[self.tableView reloadData];
}
}];
}
I didn't get correct results for Forward geocoding in certain cases. When I search for some places or hotel it shows result of some others places or areas. I have got following code. I study the following link. What url should i place to get correct results.
how can we implement the following given in following site
https://developers.google.com/places/webservice/autocomplete
A request for addresses containing "Vict" with results in French:
https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Vict&types=geocode&language=fr&key=API_KEY A request for cities containing "Vict" with results in Brazilian Portuguese:
I have implemented following but it doesn't give the results as i aspected
- (CLLocationCoordinate2D)addressLocation{
NSError *error = nil;
// NSString *lookUpString = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?address=%@&sensor=true", SearchtextField];
// NSString *API_KEY=@"AIzaSyB27SkGBzvEYKcxvZ5nmOVWvrA-6Xqf-7A";
NSString *API_KEY=@"AIzaSyCHcqJcqZbP1XpU-WB4VfRct5hpdgqisSY";
NSString *lookUpString = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/geocode/json?address=%@®ion=np&key=%@", SearchtextField,API_KEY];
lookUpString = [lookUpString stringByReplacingOccurrencesOfString:@" " withString:@"+"];
NSData *jsonResponse = [NSData dataWithContentsOfURL:[NSURL URLWithString:lookUpString]];
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonResponse options:kNilOptions error:&error];
NSArray *locationArray = [[[jsonDict valueForKey:@"results"] valueForKey:@"geometry"] valueForKey:@"location"];
NSString *statusString = [jsonDict valueForKey:@"status"];
if ([statusString isEqualToString:@"OK"])
{
locationArray = [locationArray objectAtIndex:0];
Str_Latitude= [locationArray valueForKey:@"lat"];
Str_Longitude= [locationArray valueForKey:@"lng"];
NSLog(@"LatitudeString:%@ & LongitudeString:%@", Str_Latitude, Str_Longitude);
/*Google place latitude Longitude*/
Arr_LatLong = @[Str_Latitude,Str_Longitude];
[[NSUserDefaults standardUserDefaults] setValue:Str_Latitude forKey:@"Str_Latitude"];
[[NSUserDefaults standardUserDefaults] setValue:Str_Longitude forKey:@"Str_Longitude"];
[[NSUserDefaults standardUserDefaults] synchronize];
GogLatitude = [Str_Latitude doubleValue];
Goglongitude = [Str_Longitude doubleValue];
if (Bool_SearchField) {
[self getGoogleAddress];
Bool_SearchField=FALSE;
}else{
}
}else{
UIAlertView *alertview =[[UIAlertView alloc] initWithTitle:@"Address not found" message:@"make sure you enter a valid address" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alertview show];
NSLog(@"Something went wrong, couldn't find address");
[self.tableView reloadData];
}
GogLocation.latitude = GogLatitude;
GogLocation.longitude = Goglongitude;
return GogLocation;
}
When i search for radission in
maps.google.comit shows as below
But when i search in my app it shows different locations then what I search
解决方案
I have done what you have asked in one of my apps, but the url is different.
I am posting the function that gets called each time i input something in a text field.
-(void) startAutocomplete{
NSString* baseUrl = [NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/place/queryautocomplete/json?input=%@&key=AIzaSyDz3HAmNY8NsgIhtA8gtbH-QA08Lg9tej4&types=all", self.locationTextfield.text];
NSURL *url = [NSURL URLWithString:[baseUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"Url: %@", url);
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if (connectionError!=nil) {
[[[UIAlertView alloc] initWithTitle:nil message:connectionError.localizedDescription delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil] show ] ;
}else{
NSError *error = nil;
self.searchResult= [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
//NSLog(@"result:%@",self.searchResult);
[self.tableView reloadData];
}
}];
}
