在iphone中自动滚动字幕标签

问题描述

我有一个UILabel，我想像HTML中的marquee标签一样滚动，我该怎么做？

I have an UILabel that I want to scroll like marquee tag in HTML, how am I supposed to do that?

#define LEFTSCROLLDIRECTION 0
#define RIGHTSCROLLDIRECTION 1

MarqueeLabel *marquee = [[MarqueeLabel alloc] initWithFrame:CGRectMake(10, 10, 300, 30)];
label.scrollDirection = LEFTSCROLLDIRECTION;
[self.view addSubview:marquee];

编辑

我找到了类似乎首先起作用。 。

Edit

I have found this class for this that seems to work at first..

但是这里有一个错误..如果我在UINavigationController中向前导航并在一段时间之后弹出pushViewController，则autoScrollLabel会停止动画..

But there is a fault in this.. if I navigate forward in UINavigationController and pop that pushedViewController after a time, the autoScrollLabel stops animating..

AutoScrollLabel *autoScrollLabel = [[AutoScrollLabel alloc] init];
autoScrollLabel.text = @"Hi Mom!  How are you?  I really ought to write more often.";
autoScrollLabel.textColor = [UIColor yellowColor];

推荐答案

查看开源组件，实际上叫做MarqueeLabel。

Check out this open source component, actually called MarqueeLabel.

这让这很容易。
