根据苹果示例,我可以使用TWRequest轻松发送推文,

 ACAccountStore *account = [[ACAccountStore alloc] init];
 ACAccountType *accountType = [accountaccountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

// Request access from the user to access their Twitter account
[account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) 
 {
     // Did user allow us access?
     if (granted == YES)
     {
         // Populate array with all available Twitter accounts
         NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];

         // Sanity check
         if ([arrayOfAccounts count] > 0) 
         {
             // Keep it simple, use the first account available
             ACAccount *acct = [arrayOfAccounts objectAtIndex:0];

             // Build a twitter …

当我在 Eclipse 中创建 Gradle 项目时，结果是一个嵌套项目，其中包含一个自动创建的 -lib 文件夹。关于为什么要创建它的任何想法？

在升级到swift 2.0并经历了一系列错误后,我最终得到了这个错误,我不知道如何解决:

init() 不可用:使用 init(domain:code:userInfo:)

这是代码:

override func objectsDidLoad(error: NSError?) {
 self.actInd.startAnimating()
    for var i = 0; i < (objects!.count); i++ { 
     let countObject = (objects?[i] as! PFObject)
      print( (countObject.objectId)! )
     let queryT = PFQuery(className:"Transactions")
      queryT.whereKey("eventID", equalTo:(countObject.objectId)!)
      print( queryT.countObjects() )
      self.countedEvents.append(countEvents(objectId: (countObject.objectId)!, count:  queryT.countObjects() ))
    print( (countObject.objectId)! )

    self.actInd.stopAnimating()
}
super.objectsDidLoad(NSError())
}

此处出现错误 - super.objectsDidLoad(NSError())

谢谢,斯图尔特

我正在尝试使用filteredArrayUsingPredicate与从.plist文件中的数据构建的数组.不知怎的,它似乎永远不会过滤我的数组.

这就是我的数组的构建方式:

    DrillDownAppAppDelegate *AppDelegate = (DrillDownAppAppDelegate *)[[UIApplication sharedApplication] delegate];
    self.tableDataSource = [AppDelegate.data objectForKey:@"Rows"];
    copyDataSource = [ tableDataSource mutableCopy];

然后我的谓词是这样的,

NSString *searchFor = search.text;
[tableDataSource release];
tableDataSource = [copyDataSource mutableCopy];
if ([searchFor length] > 0) {
NSLog(@"array = %@",tableDataSource);
NSPredicate *pred = [NSPredicate predicateWithFormat:@"Self beginswith[c] %@",searchFor];
    [tableDataSource filteredArrayUsingPredicate:pred];
}
