Ios MarqueeLabel不工作，它只是在屏幕上显示为UILabel

我已将链接中的文件包括在我的项目中

MarqueeLabel *continuousLabel2 = [[MarqueeLabel alloc] initWithFrame:CGRectMake(10, 440, self.view.frame.size.width-20, 20) rate:10 andFadeLength:10.0f]; 
continuousLabel2.tag = 101;
continuousLabel2.marqueeType = MLContinuous;
continuousLabel2.animationCurve = UIViewAnimationOptionCurveLinear;
continuousLabel2.continuousMarqueeExtraBuffer = 50.0f; 
continuousLabel2.numberOfLines = 1; 
continuousLabel2.opaque = YES; 
continuousLabel2.enabled = YES; 
continuousLabel2.textAlignment = NSTextAlignmentLeft; 
continuousLabel2.textColor = [UIColor colorWithRed:0.234 green:0.234 blue:0.234 alpha:1.000]; 
continuousLabel2.backgroundColor = [UIColor clearColor]; 
continuousLabel2.font = [UIFont fontWithName:@"Helvetica-Bold" size:14.000]; 
continuousLabel2.text = @"This is another long label that scrolls continuously with a custom space between labels! You can also tap it to pause and unpause it!"
[self.view addSubview :continuousLabel2];

我已经在我的项目中粘贴了上面的代码，但是文本只是显示为UILabel，而不是marquee。请告知

将此置于代码末尾

 [continuousLabel2 restartLabel];

或

[self performSelector:@selector(startlabel) withObject:nil afterDelay:1.0];
-(void)startlabel{
        [continuousLabel2 restartLabel];
}

---

我使用

resetLabel

启动字幕动画

另外，不要忘记将

labelize

属性设置为

NO

。i、 e

[self.marqueeLabel resetLabel];
self.marqueeLabel.labelize= NO;

---

由Github提供的字幕标签文档 “MarqueeLabel尽最大努力在适当的时候自动开始滚动，但有时视图/视图控制器在屏幕上的显示方式可能会使其出错。 使用restartLabel实例方法“手动”开始在MarqueeLabel上滚动

你在你的项目中导入了Quartzcore框架吗？是的，它已经导入了。好的，我测试了代码，它适合我。。我想您可能需要更改连续标签的宽度。。试着缩小它，看看这是否会产生影响。试着缩小宽度，但仍然得到相同的结果。此解决方案正在运行。谢谢你能解释一下我的代码有什么问题吗
