How to animate UILabel? - objective-c

Question

I'm using UILabel to display some dynamic text. Sometime its over lap the width of the label. I want to slide the text if the UILabel goes out of bound.
How do I do the sliding animation with UILabel? Any help?

Answer 1

Modifying my answer to address the short coming pointed out -
UILabel *label; //Previously initialized UILabel
float newX = 0.0;
float newY = 101.0f;
label.center = CGPointMake(newX, newY);
If you wanted to animate the movement, it's cake to add an animation block:
UILabel *label; //Previously initialized UILabel
float newX = 90.0f;
float newY = 101.0f;
[UIView transitionWithView:label
duration:0.5f
options:UIViewAnimationCurveEaseInOut
animations:^(void) {
label.center = CGPointMake(newX, newY);
}
completion:^(BOOL finished) {
// Do nothing
}];
Notice that we only animate the X coordinate as you want the label to slide.

When I had to do something similar, I did this.
Please notice that I'm tweening the alpha, not the position, but I hope this could help you:
[UIView animateWithDuration:0.3f animations:^{yourLabel.alpha = 0.f;}];

-(void)repeat{
[NSTimer scheduledTimerWithTimeInterval:8.0
target:self
selector:#selector(LabelAnimation)
userInfo:nil
repeats:YES];
}
-(void)LabelAnimation
{
NSArray *elements = [yourText componentsSeparatedByString:#","];
NSMutableArray *outputElements = [[NSMutableArray alloc] init];
for (int i=1;i<[elements count];i++)
[outputElements addObject:[elements objectAtIndex:i]];
NSString *outputString = [outputElements componentsJoinedByString:#","];
[UIView animateWithDuration:3.0f delay:0.2f options:UIViewAnimationOptionTransitionNone animations:^{
_header.labelHeaderName.text=outputString;
} completion:^(BOOL finished)
{
if (outputString.length == 0) {
_header.labelHeaderName.text=_strAddress(your saved address);
}
}];
}
