title: repeat display array of text in label forever
body: <p>I'm trying to repeat display array of text in label forever in xcode , 
  first I added a <code>array</code> in <code>viewDidLoad</code> method </p>
  
  <pre><code>- (void)viewDidLoad
  {
  [super viewDidLoad];
  _tweettest = @[@"tweet1",
   @"tweet2",
   @"tweet3",
   @"tweet4",
   @"tweet5"];
  
  }
  </code></pre>
  
  <p>then i add <code>NSTimer</code> object in <code>viewDidAppear</code> method </p>
  
  <pre><code>-(void) viewDidAppear:(BOOL)animated
  {
   [super viewDidAppear:animated];
   NSDate *d = [NSDate dateWithTimeIntervalSinceNow: 0.1];
    Timer1 = [[NSTimer alloc] initWithFireDate: d
   interval: 1
   target:self
   selector:@selector(Timer1Tasks)
   userInfo:nil
  repeats:YES];
  NSRunLoop *runner = [NSRunLoop currentRunLoop];
  [runner addTimer:Timer1 forMode: NSDefaultRunLoopMode];
  
  }
  </code></pre>
  
  <p>then add method which will add text to label every 1 second </p>
  
  <pre><code>-(void) Timer1Tasks
  {
  static int count = 0;
  NSString* letter = nil;
  
  
  switch(count) {
  
      case 0: letter = _tweettest[0];
          _tweetlabel.text = [NSString stringWithFormat:@"%@",  letter];
          break;
      case 1: letter = _tweettest[1];
          _tweetlabel.text = [NSString stringWithFormat:@"%@",  letter];
          break;
      case 2: letter = _tweettest[2];
          _tweetlabel.text = [NSString stringWithFormat:@"%@",  letter];
          break;
      case 3: letter = _tweettest[3];
          _tweetlabel.text = [NSString stringWithFormat:@"%@",  letter];
          break;
      case 4: letter = _tweettest[4];
          _tweetlabel.text = [NSString stringWithFormat:@"%@",  letter];
          break;
  }
  count++;
  
  
  }
  </code></pre>
  
  <p>now every thing is ok except that there is no loop to repeat view all text again forever from beginning.</p>
  
  <p>any idea will be helpful. </p>
