我已经使用Twitter API获得关注者和关注者。
我已经写了这段代码。获得关注者并关注
-(void)getTwitterAccounts
{
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
// let's request access and fetch the accounts
[accountStore requestAccessToAccountsWithType:accountType
withCompletionHandler:^(BOOL granted, NSError *error)
{
// check that the user granted us access and there were no errors (such as no accounts added on the users device)
if (granted && !error)
{
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
if ([accountsArray count] > 1) {
// a user may have one or more accounts added to their device
// you need to either show a prompt or a separate view to have a user select the account(s) you need to get the followers and friends for
} else {
[self getTwitterFriendsForAccount:[accountsArray objectAtIndex:0]];
}
} else {
// handle error (show alert with information that the user has not granted your app access, etc.)
}
}];
}
-(void)getTwitterFriendsForAccount:(ACAccount*)account
{
// In this case I am creating a dictionary for the account
// Add the account screen name
NSMutableDictionary *accountDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:account.username, @"screen_name", nil];
// Add the user id (I needed it in my case, but it's not necessary for doing the requests)
[accountDictionary setObject:[[[account dictionaryWithValuesForKeys:[NSArray arrayWithObject:@"properties"]] objectForKey:@"properties"] objectForKey:@"user_id"] forKey:@"user_id"];
// Setup the URL, as you can see it's just Twitter's own API url scheme. In this case we want to receive it in JSON
NSURL *followingURL = [NSURL URLWithString:@"http://api.twitter.com/1/friends/ids.json"];
// Pass in the parameters (basically '.ids.json?screen_name=[screen_name]')
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:account.username, @"screen_name", nil];
// Setup the request
TWRequest *twitterRequest = [[TWRequest alloc] initWithURL:followingURL
parameters:parameters
requestMethod:TWRequestMethodGET];
// This is important! Set the account for the request so we can do an authenticated request. Without this you cannot get the followers for private accounts and Twitter may also return an error if you're doing too many requests
[twitterRequest setAccount:account];
// Perform the request for Twitter friends
[twitterRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if (error) {
// deal with any errors - keep in mind, though you may receive a valid response that contains an error, so you may want to look at the response and ensure no 'error:' key is present in the dictionary
}
NSError *jsonError = nil;
// Convert the response into a dictionary
NSDictionary *twitterFriends = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&jsonError];
// Grab the Ids that Twitter returned and add them to the dictionary we created earlier
[accountDictionary setObject:[twitterFriends objectForKey:@"ids"] forKey:@"friends_ids"];
NSLog(@"%@", accountDictionary);
}];
}
但是这段代码不起作用
给我错误
NSRangeException'，原因:“* -[__ NSArrayI objectAtIndex:]:索引0超出了空数组的边界” **
为什么会这样。请帮助我解决这个问题。
最佳答案
终于我得到了解决方案。
这是获取Twitter关注者和名字的解决方案
首先，您需要获取有效用户名。这个名字你可以从
此代码。
NSString * username = [FHSTwitterEngine sharedEngine].authenticatedUsername;
使用该用户名，您可以获得所需的任何内容
NSMutableDictionary * dict1 = [[FHSTwitterEngine sharedEngine]listFriendsForUser:username isID:NO withCursor:@"-1"];
NSLog(@"====> %@",[dict1 objectForKey:@"users"] ); // Here You get all the data
NSMutableArray *array=[dict1 objectForKey:@"users"];
for(int i=0;i<[array count];i++)
{
NSLog(@"names:%@",[[array objectAtIndex:i]objectForKey:@"name"]);
}
