IOS 实现滚动文字

当然最好应该使用block的方式，在此只是标记一下。

self.firstButton.backgroundColor = [UIColorgreenColor];

CGRect frame = self.firstButton.frame;

frame.origin.x = 320;

self.firstButton.frame = frame;

[UIViewbeginAnimations:@"testAnimation"context:NULL];

[UIViewsetAnimationDuration:8.8f];

[UIViewsetAnimationCurve:UIViewAnimationCurveLinear];

[UIViewsetAnimationDelegate:self];

[UIViewsetAnimationRepeatAutoreverses:NO];

[UIViewsetAnimationRepeatCount:999999];

frame = self.firstButton.frame;

frame.origin.x = -frame.size.width;

self.firstButton.frame = frame;

[UIViewcommitAnimations];
