I am new to iOS and working on the GOOGLE-MAP-SDK. Everything is going very well, but I am not able to use the annotations in this case due to which I am not able to locate my positions which I fetched from the placeAPI of Google.
So kindly help me out with my errors.
Code File
-(IBAction)search:(id)sender
{
NSString *url = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/search/json?location=30.7343000,76.7933000&radius=500&types=food&name&sensor=true&key=AIzaSyCGeIN7gCxU8baq3e5eL0DU3_JHeWyKzic"];
//Formulate the string as URL object.
NSURL *googleRequestURL=[NSURL URLWithString:url];
// Retrieve the results of the URL.
dispatch_async(kBgQueue, ^{
NSData* data = [NSData dataWithContentsOfURL: googleRequestURL];
[self performSelectorOnMainThread:#selector(fetchedData:) withObject:data waitUntilDone:YES];
});
}
- (void)fetchedData:(NSData *)responseData {
//parse out the json data
NSError* error;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions
error:&error];
//The results from Google will be an array obtained from the NSDictionary object with the key "results".
NSArray* places = [json objectForKey:#"results"];
//Write out the data to the console.
NSLog(#"Google Data: %#", places);
}
Here is the code from which I will receive the data and want to display it on the Google map. NSLog(#"Google Data: %#", places); is giving me the out put...

i want to take 450
from the following:
NSString {status:0,val:450}
using objective c:
{status:0,val:450}
Please suggest me answer
I cannot completely understand your question . I think you have you have an JSON data like:
{
status:0;
val:450;
}
If you want this data in your app. You want to do
NSURL *blogURL = [NSURL URLWithString:#"https://your url here"];
NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];
NSError *error = nil;
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
NSDictionary *data = [dataDictionary objectForKey:#"status"];
NSDictionary *item = [data objectForKey:#"val"];
Your JSON Data get in Dictionary format. You can access the Data using the Key. In here your keys are status and val.
I hope this links are help for you.

I have implemented the google place search API in IOS and enabled the API in the developer console and used the below code but its shows error that "This IP, site or mobile application is not authorized to use this API key. Request received from IP address 122.173.223.114, with empty refer"
After regenerate the API key its shows API key is expired and after sometime its shows the same above errors. Please help someone.
-(void) queryGooglePlaces: (NSString *) googleType {
// Build the url string to send to Google. NOTE: The kGOOGLE_API_KEY is a constant that should contain your own API key that you obtain from Google. See this link for more info:
// https://developers.google.com/maps/documentation/places/#Authentication
NSString *url = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/search/json?location=%f,%f&radius=%#&types=%#&sensor=true&key=%#", appDel.objLocationManager.location.coordinate.latitude, appDel.objLocationManager.location.coordinate.longitude, [NSString stringWithFormat:#"%i", appDel.currenDist],googleType, kGOOGLE_API_KEY];
//Formulate the string as a URL object.
NSURL *googleRequestURL=[NSURL URLWithString:url];
// Retrieve the results of the URL.
dispatch_async(kBgQueue, ^{

}
-(void)fetchedData:(NSData *)responseData {
//parse out the json data
if (responseData==nil) {
}else{
NSError* error;
NSDictionary* json = [NSJSONSerialization

options:kNilOptions
error:&error];
//The results from Google will be an array obtained from the NSDictionary object with the key "results".
NSArray* places = [json objectForKey:#"results"];
//Write out the data to the console.
NSLog(#"Google Data: %#", json);
}
}
I did it with use of AFNetworking class Try this one,
#define kGoogleAutoCompleteAPI #"https://maps.googleapis.com/maps/api/place/autocomplete/json?key=%#&input=%#"
-(void)getAutoCompletePlaces:(NSString *)searchKey
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// set request timeout
manager.requestSerializer.timeoutInterval = 5;
NSString *url = [[NSString stringWithFormat:kGoogleAutoCompleteAPI,GoogleDirectionAPI,searchKey] stringByReplacingOccurrencesOfString:#" " withString:#"+"];
NSLog(#"API : %#",url);
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
[MBProgressHUD hideHUDForView:self.view animated:YES];
NSDictionary *JSON = responseObject;
predictions = [NSMutableArray array];
// success
AutomCompletePlaces *places = [AutomCompletePlaces modelObjectWithDictionary:JSON];
[arrSuggestionData removeAllObjects];
if (!arrSuggestionData) {
arrSuggestionData = [NSMutableArray array];
}
for (Predictions *pred in places.predictions)
{
[arrSuggestionData addObject:pred.predictionsDescription];
}
[self.Tbl_suggestion reloadData];
} failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
}
NSString *connection = #"http:"(link);
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSError *error = nil;
NSURL *url = [NSURL URLWithString:connection];
NSString *json = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];
NSLog(#"\nJSON: %# \n Error: %#", json, error);
if(!error) {
NSData *jsonData = [json dataUsingEncoding:NSUTF8StringEncoding];
NSLog(#"%#",jsonData);
NSMutableArray *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];
NSLog(#"JSON: %#", jsonDict);
}
});
The above code returns :
JSON: "{\"value\":[{\"Id\":\" }}
but
NSData is 69746963 735c222c 5c224973 41767469 76655c22 3a5c2231 5c222c
and jsonDict returns (null).
I am confused what may be going on.
Can somebody please help me figure it out.
I am trying to get the JSON data but it returns null.
Thanks
You say the server gave you this:
JSON: "{\"value\":[{\"Id\":\" }}
If I remove the backslashes that were added by the NSLog command, the actual JSON that you received was
{"value":[{"Id":" }}
That isn't valid JSON. That's all there is to it; the server sent you rubbish data, and there is no way to get any information from it. Contact the people creating the server software and ask them to fix the problem.
And you really, really need to distinguish between what an object really contains, and what NSLog prints. NSLog prints the contents of an NSData object by displaying each byte as two hexadecimal digits.
Try one of these (array or dictionary) without converting it into JSON, depending on what u want :
NSString *connection = #"http://(link)";
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{
NSDictionary *jsonDict = [NSDictionary dictionaryWithContentsOfURL:[NSURL URLWithString:connection]];
NSArray *jsonArray = [NSArray arrayWithContentsOfURL:[NSURL URLWithString:connection]];
NSLog(#"DICT: %# ARRAY: %#", jsonDict, jsonArray);
});
I haven't tried it, please paste results?
By the look of your NSString response, it starts with { and ends with } which means it is a NSDictionary.
Change :
NSMutableArray *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];
to :
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:jsonData options:nil error:&error];
I'been trying to parse JSON data retrieved from my server, but when the server sends JSON with accents or question marks, it shows as null values.
It would be great if someone could help me solve this issue.
Here is my code
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urls=[NSString stringWithFormat:#"http://myserver.myserver/myserver"];
NSLog(#"%#",urls);
NSURL *url =[NSURL URLWithString:urls];
NSData* data = [NSData dataWithContentsOfURL:url];
//fetch the data to the JSON Foundation opject.
[self performSelectorOnMainThread:#selector(fetchedData:)
withObject:data waitUntilDone:YES];
}
- (void)fetchedData:(NSData *)responseData {
//parse out the json data
NSError* error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
//process the JSON Foundation object to the view.
[self processData:json];
}
-(void)processData:(NSDictionary *) JSONObject{
NSString *kl = [JSONObject valueForKey:#"qlk"];
NSString *an= [JSONObject valueForKey:#"alk"];
NSString *bn = [JSONObject valueForKey:#"blk"];
NSString *cn =[JSONObject valueForKey:#"clk"];
NSString *dn =[JSONObject valueForKey:#"dlk"];
NSString *correcta =[JSONObject valueForKey:#"rlk"];
qkl.text=pregunta;
akl.text =an;
bkl.text =bn;
ckl.text=cn;
dkl.text=dn;
}
And the JSON
{ "qlk": "¿De qué color es el caballo blanco de Simon Bolivar?", "alk": "Negro", "blk": "Cafe", "clk": "Blanco", "dlk": "Rojo", "rlk": "c" }
Thanks.
I am building an app that makes use of google places api,i use this url
the desired link doesnt produce any results when i use it in the browser
and i use json to parse the data coming from google places but i get this unusual warning which says NSString may not respond to JSONValue
the code is as follows
-(IBAction)nearbyLocations:(id)sender
{
NSString *url=[NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/search/json?location=37.329558,122.025002&radius=500&types=atm&sensor=false&key=AIzaSyCIZ8MxCoMsfgj0ytE7azXGfjs_E__2Nhw"];
NSURL *googleRequestURL=[NSURL URLWithString:url];
dispatch_async(kBgQueue, ^{
NSData* data = [NSData dataWithContentsOfURL: googleRequestURL];
[self performSelectorOnMainThread:#selector(fetchedData:) withObject:data waitUntilDone:YES];
});
}
-(void)fetchedData:(NSData *)responseData
{
//parse out the json data
//NSError* error;
NSString *jsonString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"%#",jsonString);
NSDictionary* json =[jsonString JSONValue];
//[NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
//The results from Google will be an array obtained from the NSDictionary object with the key "results".
NSArray* places = [json objectForKey:#"results"];
//Write out the data to the console.
NSLog(#"Google Data: %#", places);
}
You need a larger radius. In the URL you provided, I changed radius=500 to radius=5000 and it works. New URL. Basically there are no ATMs within 500 meters of that lat/long, but there are ATMs within 5000 meters.
That's one issue. The other issue is in Tsar's comment to your question.
