问题
When I run below code with iOS 6.0, Its working
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[account requestAccessToAccountsWithType:accountType options:nil
completion:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
//MY CODE
}
});
}];
and When I run this code with iOS 5.0 or 5.1, It crashes with following output,
*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '-[ACAccountStore requestAccessToAccountsWithType:options:completion:]:
unrecognized selector sent to instance 0x68a57c0'
Don't know about this weird crash log..
Please tell me, How to get rid of this..
回答1:
Use below method:
[account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
{
if (granted) {
//Your code
}
}
}];

This is a bit late, but the reason you're getting that error is that requestAccessToAccountsWithType:options:completion: is new in iOS 6.
In iOS 5 and earlier use the requestAccessToAccountsWithType:withCompletionHandler method instead (this method is deprecated in iOS 6)
See the docs: https://developer.apple.com/library/ios/documentation/Accounts/Reference/ACAccountStoreClassRef/Reference/Reference.html#//apple_ref/doc/uid/TP40011021-CH1-SW12

Try update for this:
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
// iOS 6
if ( [account respondsToSelector:@selector(requestAccessToAccountsWithType: options: completion:)] )
{
[account requestAccessToAccountsWithType:accountType options:nil
completion:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
//MY CODE
}
});
}];
}
// iOS 5
else if ( [account respondsToSelector:@selector(requestAccessToAccountsWithType: withCompletionHandler:)] )
{
[account requestAccessToAccountsWithType:accountType
withCompletionHandler:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
//MY CODE
}
});
}];
}
else
{
// iOS 4 or less
}

Thanks @CReaTuS, I want to clarify this up to some more bit, Note that in case of iOS6 we make SLRequest where in iOS5 we have to perform request using TWRequest. See below-
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
if ( [accountStore respondsToSelector:@selector(requestAccessToAccountsWithType: options: completion:)] )
{
[accountStore requestAccessToAccountsWithType:accountType options:nil
completion:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
if ([accountsArray count] > 0) {
// Grab the initial Twitter account to tweet from.
ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
NSMutableDictionary *tempDict = [[NSMutableDictionary alloc] init];
[tempDict setValue:@"Twitter_Name" forKey:@"screen_name"];
[tempDict setValue:@"true" forKey:@"follow"];
//Code specific to iOS6 or later
SLRequest *followRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:[NSURL URLWithString:@"https://api.twitter.com/1.1/friendships/create.json"] parameters:tempDict];
// To unfollow hit URL-https://api.twitter.com/1.1/friendships/destroy.json
[followRequest setAccount:twitterAccount];
[followRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
NSString *output = [NSString stringWithFormat:@"HTTP response status: %i", [urlResponse statusCode]];
NSLog(@"%@", output);
if (error) {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show follow request failed
});
}
else {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show success
});
}
}];
}
}
});
}];
}
else if ( [accountStore respondsToSelector:@selector(requestAccessToAccountsWithType: withCompletionHandler:)] )
{
[accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
if ([accountsArray count] > 0) {
// Grab the initial Twitter account to tweet from.
ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
NSMutableDictionary *tempDict = [[NSMutableDictionary alloc] init];
[tempDict setValue:@"Twitter_Name" forKey:@"screen_name"];
[tempDict setValue:@"true" forKey:@"follow"];
//Code specific to iOS5
TWRequest *followRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"https://api.twitter.com/1/friendships/create.json"]
parameters:tempDict
requestMethod:TWRequestMethodPOST];
[followRequest setAccount:twitterAccount];
[followRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
NSString *output = [NSString stringWithFormat:@"HTTP response status: %i", [urlResponse statusCode]];
NSLog(@"%@", output);
if (error) {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show follow request failed
});
}
else {
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show success
});
}
}];
}
}
});
}];
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
//Update UI to show follow request completely failed
});
}
Happy coding :)
