iOS : How to fetch tweet from Twitter API 1.1 - ios

Question

Twitter has deprecated its API 1.0 and implemented new API 1.1
As per the new API we need to authentication before fetching the public time line.
I read the new API documentation here: https://dev.twitter.com/docs/api/1.1
but I have not clear idea, how to implement it in iOS.
Can anyone tell me the best way to fetch public time-line form Twitter using the API 1.1
Thanks in advance.

Answer 1

First, you need to Authenticate your request (Get permission).
second, see follow these steps:
1.Download FHSTwitterEngine Twitter Library.
2.Add the folder FHSTwitterEngine" to your project and #import "FHSTwitterEngine.h".
3.add SystemConfiguration.framework to your project.
Usage : 1.in the [ViewDidLoad] add the following code.
UIButton *logIn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
logIn.frame = CGRectMake(100, 100, 100, 100);
[logIn setTitle:#"Login" forState:UIControlStateNormal];
[logIn addTarget:self action:#selector(showLoginWindow:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:logIn];
[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:#"<consumer_key>" andSecret:#"<consumer_secret>"];
[[FHSTwitterEngine sharedEngine]setDelegate:self];
and don't forget to import the delegate FHSTwitterEngineAccessTokenDelegate.
you need to get the permission for your request, with the following method which will present Login window:
- (void)showLoginWindow:(id)sender {
[[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromViewController:self withCompletion:^(BOOL success) {
NSLog(success?#"L0L success":#"O noes!!! Loggen faylur!!!");
}];
}
when the Login window is presented, enter your Twitter Username and Password to authenticate your request.
add the following methods to your code:
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[FHSTwitterEngine sharedEngine]loadAccessToken];
NSString *username = [[FHSTwitterEngine sharedEngine]loggedInUsername];// self.engine.loggedInUsername;
if (username.length > 0) {
lbl.text = [NSString stringWithFormat:#"Logged in as %#",username];
[self listResults];
} else {
lbl.text = #"You are not logged in.";
}
}
- (void)storeAccessToken:(NSString *)accessToken {
[[NSUserDefaults standardUserDefaults]setObject:accessToken forKey:#"SavedAccessHTTPBody"];
}
- (NSString *)loadAccessToken {
return [[NSUserDefaults standardUserDefaults]objectForKey:#"SavedAccessHTTPBody"];
}
4.Now you are ready to get your request, with the following method(in this method I created a `Twitter` search for some `Hashtag`, to get the screen_name for example):
- (void)listResults {
dispatch_async(GCDBackgroundThread, ^{
#autoreleasepool {
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
// the following line contains a FHSTwitterEngine method wich do the search.
dict = [[FHSTwitterEngine sharedEngine]searchTweetsWithQuery:#"#iOS" count:100 resultType:FHSTwitterEngineResultTypeRecent unil:nil sinceID:nil maxID:nil];
// NSLog(#"%#",dict);
NSArray *results = [dict objectForKey:#"statuses"];
// NSLog(#"array text = %#",results);
for (NSDictionary *item in results) {
NSLog(#"text == %#",[item objectForKey:#"text"]);
NSLog(#"name == %#",[[item objectForKey:#"user"]objectForKey:#"name"]);
NSLog(#"screen name == %#",[[item objectForKey:#"user"]objectForKey:#"screen_name"]);
NSLog(#"pic == %#",[[item objectForKey:#"user"]objectForKey:#"profile_image_url_https"]);
}
dispatch_sync(GCDMainThread, ^{
#autoreleasepool {
UIAlertView *av = [[UIAlertView alloc]initWithTitle:#"Complete!" message:#"Your list of followers has been fetched" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[av show];
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}
});
}
});
}
That's all. I just got the screen_name from a search Query, you can get a timeline for a user using the following methods:
// statuses/user_timeline
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count;
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count sinceID:(NSString *)sinceID maxID:(NSString *)maxID;
instead of the search method above.
Note: see the FHSTwitterEngine.h to know what method you need to use.
Note: to get the <consumer_key> and the <consumer_secret> you need to

You might be interested in the following library.
https://github.com/nst/STTwitter
It is a lightweight Objective-C wrapper for Twitter REST API 1.1.
Look at the ReadMe and Demo project for examples
This is just one of the many methods the library has:
- (void)getUserTimelineWithScreenName:(NSString *)screenName
successBlock:(void(^)(NSArray *statuses))successBlock
errorBlock:(void(^)(NSError *error))errorBlock;
