代碼如下
- (void)viewDidLoad {
[super viewDidLoad];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(200, 300, 0, 0)];
label.text = @"沒有生來天賦過人,面對人山人海只剩一些勤懇...";
[label sizeToFit];
[self.view addSubview:label];
/**
如果設(shè)置為YES 代表動畫每次重復(fù)執(zhí)行的效果跟上次相反
[UIView setAnimationRepeatAutoreverses:YES];
*/
[UIView beginAnimations:@"Marquee" context:NULL];
//動畫時長
[UIView setAnimationDuration:15.0f];
//動畫節(jié)奏
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
//重復(fù)次數(shù)
[UIView setAnimationRepeatCount:10000];
CGRect lbframe = label.frame;
lbframe.origin.x = - lbframe.size.width;
label.frame = lbframe;
[UIView commitAnimations];
}
