代码如下
- (void)viewDidLoad {
[super viewDidLoad];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(200, 300, 0, 0)];
label.text = @"没有生来天赋过人,面对人山人海只剩一些勤恳...";
[label sizeToFit];
[self.view addSubview:label];
/**
如果设置为YES 代表动画每次重复执行的效果跟上次相反
[UIView setAnimationRepeatAutoreverses:YES];
*/
[UIView beginAnimations:@"Marquee" context:NULL];
//动画时长
[UIView setAnimationDuration:15.0f];
//动画节奏
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
//重复次数
[UIView setAnimationRepeatCount:10000];
CGRect lbframe = label.frame;
lbframe.origin.x = - lbframe.size.width;
label.frame = lbframe;
[UIView commitAnimations];
}
