I am creating an app that uses Google Place. Before I used to use Yahoo's api and had to use a url that was responsible for local search that was provided by yahoo. The url was following:
http://local.yahooapis.com/LocalSearchService/V3/localSearch?appid=SF0DVEvV34G4GnXEDU4SXniaDebJ_UvC1G1IuikVz3vpOJrBpyD.VqCJCVJHMh99He3iFz1Rzoqxb0b7Z.0-
Now since yahoo's api is discontinued I have decided to switch over to Google Place. But I cannot find an Url to use. I just dowlod the framework and use the api key. Where can I find such url for Google Place.
Register for the Google Places API by following the linke provided below:
https://code.google.com/apis/console
Refer Code Link for places Auto Search
https://github.com/AdamBCo/ABCGooglePlacesAutocomplete
NSString *const apiKey = #"*****23xAHRvnOf2BVG8o";
NSString * searchWord = #"search some place "
NSString *urlString = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=%#&types=establishment|geocode&radius=500&language=en&key=%#",searchWord,apiKey];
pragma mark - Network Methods
-(void)retrieveGooglePlaceInformation:(NSString *)searchWord withCompletion:(void (^)(BOOL isSuccess, NSError *error))completion {
if (!searchWord) {
return;
}
searchWord = searchWord.lowercaseString;
self.searchResults = [NSMutableArray array];
if ([self.searchResultsCache objectForKey:searchWord]) {
NSArray * pastResults = [self.searchResultsCache objectForKey:searchWord];
self.searchResults = [NSMutableArray arrayWithArray:pastResults];
completion(YES, nil);
} else {
NSString *urlString = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=%#&types=establishment|geocode&radius=500&language=en&key=%#",searchWord,apiKey];
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

Hi fairly new to iOS just trying to connect the app to an API and get my token using Authentication. I have tried a lot of different options and just can't seem to get my head around it. All i'm trying to do is obtain my token. Can anyone see where I'm going wrong? The API documentation is here: https://simplybook.me/en/api/developer-api
NSURL *url = [NSURL URLWithString:#"http://user-api.simplybook.me/login/"];
NSURLSession *session = [NSURLSession sharedSession];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:#"myloginname" forHTTPHeaderField:#"X-Company-Login"];
[request setValue:#"mytokenhere" forHTTPHeaderField:#"X-Token"];
NSURLSessionDataTask *downloadTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (!error) {
id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSArray * resultDict =[json objectForKey:#"name"];
NSLog(#"%#", resultDict);
} else {
NSLog(#"%#", error);
}
}];
[downloadTask resume];
Instead of declaring NSURLSession like this:
NSURLSession *session = [NSURLSession sharedSession];
Try this instead:
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:#"https://user-api.simplybook.me/login/"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
And also, make sure you've declared the NSURLSessionDelegate protocol in your header file.
I will give you sample code for getting token but this is regarding to the access and refresh token.You can understand it very clearly now.
ViewController.m
- (void)viewDidLoad {
[super viewDidLoad];

I make a call to the youtube API to get the title of a video. I then want to display the title of the video on the screen in a table. How do I access the title after the block has finished executing?
Here's the code to get the title
-(void)getVideoTitle:(NSString *)urlStr success:(void (^)(NSDictionary *responseDict))success{
urlStr = [NSString stringWithFormat:#"https://www.googleapis.com/youtube/v3/videos?part=contentDetails%%2C+snippet%%2C+statistics&id=%#&key={API_KEY}",urlStr];
NSURL *url = [[NSURL alloc] initWithString:urlStr];
// Create your request
NSURLRequest *request = [NSURLRequest requestWithURL:url];
// Send the request asynchronously
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *connectionError) {
// Callback, parse the data and check for errors
if (data && !connectionError) {
NSError *jsonError;
NSDictionary *jsonResult = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&jsonError];
if (!jsonError) {
success(jsonResult);
// NSLog(#"Response from YouTube: %#", jsonResult);
}
}
}] resume];
}
Here's how I call the above function:
[self getVideoTitle:#"zB4I68XVPzQ" success:^(NSDictionary *responseDict){
NSArray *itemsArray = [responseDict valueForKey:#"items"];
NSDictionary *item = itemsArray[0];
NSDictionary* snippet = [item valueForKey:#"snippet"];
NSString *title = [snippet valueForKey:#"title"];
}];
How do I get access the title variable outside the block after the block has finished executing?
I have tried the following with no luck
dispatch_async(dispatch_get_main_queue(), ^{
[self updateMyUserInterfaceOrSomething];
});
In your code:
NSString* recievedTitle __block = nil; //title is here, after block below run
[self getVideoTitle:#"zB4I68XVPzQ" success:^(NSDictionary *responseDict){
NSArray *itemsArray = [responseDict valueForKey:#"items"];
NSDictionary *item = itemsArray[0];
NSDictionary* snippet = [item valueForKey:#"snippet"];
recievedTitle = [snippet valueForKey:#"title"]; //here you write it
// or
NSString *title = [snippet valueForKey:#"title"];
[self updateInterfaceWithTitle: title]
}];
///
- (void)updateInterfaceWithTitle:(NSString*)title{
//use title here
}
I have an iOS app with a table view and I want to get the table items from an extern php file which gives me a json string. Now I try to store the data from the php file to the data variable. Here is my code:
- (NSMutableArray *)data {
if(!_data){
_data = [[NSMutableArray alloc] init];
NSURLSession *session = [NSURLSession sharedSession];
NSString *url = [NSString stringWithFormat:#"http://www.example.net/something/bla.php"];
NSURLSessionDataTask *dataTask = [session dataTaskWithURL:[NSURL URLWithString:url] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSString *errorCode = [json valueForKey:#"error"];
if([errorCode isEqualToString:#"e0"]){
NSArray *persons = [json objectForKey:#"persons"];
for (int i = 0; i < [persons count]; i++) {
NSString *person = [[persons objectAtIndex:i] objectForKey:#"name"];
[_data addObject:person];
}
}
NSLog(#"3.: %#", _data); // Full
}];
[dataTask resume];
NSLog(#"2.: %#", _data); // Empty
}
NSLog(#"1.: %#", _data); // Empty
return _data;
}
How can I return the result of the url session now? As you can see on my comments, the _data array is only filled on NSLog 3 and it is empty on 1 and 2. Would be nice if someone could tell me what I must change.
In Below code run so i get a response from url but when i try to get encodedPoints it give me a null value. also i update RegexKitLite but prob. not solve. Any suggestion are welcome Thank you advance.
NSString* saddr = [NSString stringWithFormat:#"%f,%f", f.latitude, f.longitude];
NSString* daddr = [NSString stringWithFormat:#"%f,%f", t.latitude, t.longitude];
NSString* apiUrlStr = [NSString stringWithFormat:#"http://maps.googleapis.com/maps/api/directions/json?origin=%#&destination=%#&sensor=false", saddr, daddr];
// http://maps.googleapis.com/maps/api/directions/json?origin=41.029598,28.972985&destination=41.033586,28.984546&sensor=false%EF%BB%BF%EF%BB%BF
NSURL *apiUrl = [NSURL URLWithString:[apiUrlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSLog(#"api url: %#", apiUrl);
NSString *apiResponse = [NSString stringWithContentsOfURL:apiUrl encoding:nil error:nil];
NSString* encodedPoints = [apiResponse stringByMatching:#"points:\\\"([^\\\"]*)\\\"" capture:1L];
NSLog(#"encodedPoints: %#", encodedPoints);
if (encodedPoints) {
return [self decodePolyLine:[encodedPoints mutableCopy]];
}
else {
return NO;
}
I think its not a good way to do API request synchronously, especially when user' phone has poor internet connection, it will slow down the responsiveness of your application. So you should do an asynchronous API request with NSURLSession.
Also, the Directions API might return more than one routes for your request. So its better to use a NSArray to store your polyline points.
Sample code:
- (void)getPolyline {
NSURL *url = [[NSURL alloc] initWithString:#"https://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&key=YOUR_API_KEY"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (!error) {
NSError *jsonError;
NSDictionary *dict = (NSDictionary*)[NSJSONSerialization JSONObjectWithData:data options:nil error:&jsonError];
if (!jsonError) {
NSArray *routesArray = (NSArray*)dict[#"routes"];
NSMutableArray *points = [NSMutableArray array];
for (NSDictionary *route in routesArray) {
NSDictionary *overviewPolyline = route[#"overview_polyline"];
[points addObject:overviewPolyline[#"points"]];
}
NSLog(#"%#", points);
}
} else {
//print error message
NSLog(#"%#", [error localizedDescription]);
}
}] resume];
}
I want to post a tweet to Twitter when user taps a button in the application. I don't want to use the TWTweetComposeViewController so that the user again need to tap the Send button. I want to post tweet on tap on a button inside the application. (Using iOS Twitter Framework)
Is there any way to do this ?
Thanks
Use below code to do post image and text without showing ViewContoller . This is called silent Post.
- (void) shareOnTwitterWithMessage:(NSString *)message {
ACAccountStore *twitterAccountStore = [[ACAccountStore alloc]init];
ACAccountType *TWaccountType= [twitterAccountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[twitterAccountStore requestAccessToAccountsWithType:TWaccountType options:nil completion:
^(BOOL granted, NSError *e) {
if (granted) {
NSArray *accounts = [twitterAccountStore accountsWithAccountType:TWaccountType];
twitterAccounts = [accounts lastObject];
NSDictionary *dataDict = #{#"status": message};
[self performSelectorInBackground:#selector(postToTwitter:) withObject:dataDict];
}
else {
return ;
}
}];
}
- (void)postToTwitter:(NSDictionary *)dataDict{
NSURL *requestURL = [NSURL URLWithString:#"https://api.twitter.com/1.1/statuses/update_with_media.json"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL parameters:dataDict];
NSData *imageData = UIImagePNGRepresentation([UIImage imageNamed:#"icon#2x.png"]);
[request addMultipartData:imageData
withName:#"media[]"
type:#"image/jpeg"
filename:#"image.jpg"];
request.account = twitterAccounts;
[request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response, NSError *error) {
if(!error){
NSDictionary *list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
if(![list objectForKey:#"errors"]){
if([list objectForKey:#"error"]!=nil){
//Delegate For Fail
return ;
}
}
}
}];
}
Try this:
NSString *statusesShowEndpoint = #"https://api.twitter.com/1.1/statuses/update.json";
NSDictionary *params = #{#"status": #"Hello, my first autopost tweet..."};
NSError *clientError;
NSURLRequest *request = [[[Twitter sharedInstance] APIClient]
URLRequestWithMethod:#"POST"
URL:statusesShowEndpoint
parameters:params
error:&clientError];
if (request) {
[[[Twitter sharedInstance] APIClient]
sendTwitterRequest:request
completion:^(NSURLResponse *response,
NSData *data,
NSError *connectionError) {
if (data) {
// handle the response data e.g.
NSError *jsonError;
NSDictionary *dicResponse = [NSJSONSerialization
JSONObjectWithData:data
options:0
error:&jsonError];
NSLog(#"%#",[dicResponse description]);
}
else {
NSLog(#"Error code: %ld | Error description: %#", (long)[connectionError code], [connectionError localizedDescription]);
