私はiOS6用のFacebookとTwitterを使用しています。うまくいっています。しかし、アラートビューを表示しているとき、アプリはTwitterとFacebookの両方でクラッシュしています。
以下はFacebookのコードです。この行にコメント[alert show]; すると、うまく機能しています。どこに間違いがあるのかわかりません。
-(IBAction)signInWithTweetPresses:(id)sender
{
if([TWTweetComposeViewController canSendTweet])
{
self.view.userInteractionEnabled=NO;
self.navigationController.navigationBar.userInteractionEnabled=NO;
[self.spinner startAnimating];
NSLog(@"signInWithTweetPresses called");
ACAccountStore *store = [[ACAccountStore alloc] init];
ACAccountType *twitterType = [store accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
NSLog(@"store in aap delegate %@ ",store);
NSLog(@"twittertype in aap delegate %@ ",twitterType);
[store requestAccessToAccountsWithType:twitterType withCompletionHandler:^(BOOL granted, NSError *error) {
if(granted) {
// Remember that twitterType was instantiated above
NSArray *twitterAccounts = [store accountsWithAccountType:twitterType];
//////////////////
if ([twitterAccounts count] > 0) {
// Grab the initial Twitter account to tweet from.
ACAccount *fbAccount = [twitterAccounts objectAtIndex:0];
NSLog(@"%@",fbAccount);
NSLog(@"accountsArray/loginWithFacebookClicked is %@",twitterAccounts);
NSLog(@"username---%@\n accountDescription---%@ \n credential=====%@ \n fbAccount====%@",fbAccount.username,fbAccount.accountDescription, fbAccount.credential,fbAccount);

NSLog(@"tempUserID is name is %@",tempUserID);
self.emailStr=fbAccount.accountDescription;
self.nameForFacebook_String=fbAccount.username;
// self.fID_String=fbAccount.identifier;
self.fID_String = [NSString stringWithFormat:@"%@", [[fbAccount valueForKey:@"properties"] valueForKey:@"user_id"]] ;
NSLog(@"self.fID_String is idd d is %@",self.fID_String);
appDelegate.isForTwitterAlertBool=YES;
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@" " message:@"Successfully Logged in " delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil , nil];
[alertView show];
}
NSLog(@"twitter cata in aap delegate %@ ",twitterAccounts);
}
else{
[self.spinner stopAnimating];
self.view.userInteractionEnabled=YES;
self.navigationController.navigationBar.userInteractionEnabled=YES;
