如何更改导航栏中标题的大小以适合文本

好吧，我需要更改导航控制栏上的文本，以适应比可用空间更长的电影“标题”。我已经看到更多使用这样的标签调整文本大小的代码：

  UILabel *bigLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
bigLabel.text = titoloSource;
bigLabel.font = [UIFont systemFontOfSize:22.0];
[bigLabel setFont:[UIFont boldSystemFontOfSize:16.0]];
[bigLabel setBackgroundColor:[UIColor clearColor]];
[bigLabel setTextColor:[UIColor whiteColor]];
[bigLabel setText:self.title];
[self.navigationController.navigationBar.topItem setTitleView:bigLabel];
self.navigationItem.titleView = bigLabel;

但我知道appel GUI 行指南说我们不能制作低于特定尺寸的小文本。现在我想：为什么我不能制作动画滑块文本？

那么，有人知道一种方法来制作动画文本，滚动标签内的所有“标题”？？？

谢谢

Well I need to change a text on my navigation control bar to fit a movie "title" longer than the space available. I've see more code for resize the text using a label like this:

  UILabel *bigLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
bigLabel.text = titoloSource;
bigLabel.font = [UIFont systemFontOfSize:22.0];
[bigLabel setFont:[UIFont boldSystemFontOfSize:16.0]];
[bigLabel setBackgroundColor:[UIColor clearColor]];
[bigLabel setTextColor:[UIColor whiteColor]];
[bigLabel setText:self.title];
[self.navigationController.navigationBar.topItem setTitleView:bigLabel];
self.navigationItem.titleView = bigLabel;

But I Know that the appel GUI line guide say that we can't make a small text below a certain measure. Now I've think: WHY CAN'T I MAKE an animated slider text?

So, Someone know a way to make a text animated that scroll all the "title" inside a label???

thanks
