How to move text from right to left in iOS programmatically

Question

I want to show some text in my app like moving text (Scrolling with animation from right to left). How to do this programmatically?

I took UIViewcontroller

Answer 1

Use the below method

- (void)marqueeLabel:(UILabel *)label
{
    __block UILabel *labelToBeMarqueed = label;
    __block CGRect labelFrame = labelToBeMarqueed.bounds;
    labelFrame.origin.x = [UIScreen mainScreen].bounds.size.width;
    labelToBeMarqueed.frame = labelFrame;
    [UIView animateWithDuration:2.0f
                 animations:^{
                     labelFrame.origin.x = -[UIScreen mainScreen].bounds.size.width;
                     labelToBeMarqueed.frame = labelFrame;
                 } completion:^(BOOL finished) {
                     [self marqueeLabel:label];
                 }];
}

Pass the label that you want to move from right to left to this method. Add a condition to stop the animation as this method loops continuously. You can change the animation duration as required.

Answer 2

for Swift just run this func:

 func startMarqueeLabelAnimation() {

    DispatchQueue.main.async(execute: {

        UIView.animate(withDuration: 20.0, delay: 1, options: ([.curveLinear, .repeat]), animations: {() -> Void in
            self.marqueeLabel.center = CGPoint(x: 0 - self.marqueeLabel.bounds.size.width / 2, y: self.marqueeLabel.center.y)

        }, completion:  nil)

    })
}

Add View with background colour.

UIView *animatedLblView = [[UIView alloc]initWithFrame:CGRectMake(0, 75, self.view.frame.size.width, 30)];
animatedLblView.backgroundColor = [UIColor colorWithRed:0.00 green:0.34 blue:0.61 alpha:1.0];
[self.view addSubview:animatedLblView];
//Our animated component(UIButton)
_animatingButton = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width+100, 30)];
[_animatingButton setTitle:@"Upload documents, please contact 1234567890" forState:UIControlStateNormal];
[animatedLblView addSubview:_animatingButton];
//Timer
[NSTimer scheduledTimerWithTimeInterval:1.0
                                 target:self
                               selector:@selector(LabelAnimation)
                               userInfo:nil
                                repeats:nil];

-(void)LabelAnimation {
    //Set animation
    [UIView animateWithDuration:10.0f delay:0.0f options:UIViewAnimationOptionTransitionNone animations:^{
    _animatingButton.frame = CGRectMake(-(self.view.frame.size.width+100), 0, self.view.frame.size.width+100, 30);
    } completion:^(BOOL finished) {
     _animatingButton.frame = CGRectMake(self.view.frame.size.width, 0, 0, 30);
        // Call the same function
        [self LabelAnimation];
     }];
}
