iOS - UILabels and Gestures - ios

Question

I have UILabels that get animated which move left and right on the screen, and I want to be able to drag them even while they are being animated. Anyone have any idea how to do that?
WordLabel *firstWordLabel = [[WordLabel alloc] initWithFrame:CGRectMake(x, 100, 10, 35) andWithWord:firstWord];
firstWordLabel.text = firstWord.word;
[firstWordLabel sizeToFit];
firstWordLabel.userInteractionEnabled = YES;
UIPanGestureRecognizer *gesture = [[UIPanGestureRecognizer alloc]
initWithTarget:self
action:#selector(labelDragged:)];
[firstWordLabel addGestureRecognizer:gesture];
[self.view addSubview:firstWordLabel];
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGRect newRect = firstWordLabel.frame;
newRect.origin.x = floor(screenWidth/2);
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:2.0];
firstWordLabel.frame = newRect;
[UIView commitAnimations];

Answer 1

Don't u know use of beginAnimations, commitAnimations are discouraged after iOS 4 and later see this so use block based animation methods instead for example
u can use like below
try this hope this might helps
//first create a view which holds the label for example
UIView *holderView = [[UIView alloc]initWithFrame:CGRectMake(x, 100, 10, 35)];
WordLabel *firstWordLabel = [[WordLabel alloc] initWithFrame:holderView.bounds andWithWord:firstWord];
firstWordLabel.text = firstWord.word;
[firstWordLabel sizeToFit];
firstWordLabel.userInteractionEnabled = YES;
UIPanGestureRecognizer *gesture = [[UIPanGestureRecognizer alloc]
initWithTarget:self
action:#selector(labelDragged:)];
[holderView addGestureRecognizer:gesture];
[holderView addSubview:firstWordLabel];
[self.view addSubview:holderView];
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGRect newRect = firstWordLabel.frame;
newRect.origin.x = floor(screenWidth/2);
//add the block based animation with option UIViewAnimationOptionAllowUserInteraction
[UIView animateWithDuration:2.0f delay:0.0f options:UIViewAnimationOptionAllowUserInteraction animations:^{
holderView.frame = newRect;
} completion:^(BOOL finished) {
NSLog(#"completed");
}];
for what i did like below try it in new project for testing
- (void)viewDidLoad
{
UIView *holderView = [[UIView alloc]initWithFrame:CGRectMake(20, 100, 50, 35)];
firstWordLabel = [[UILabel alloc]initWithFrame:holderView.bounds]; //is a member variable
firstWordLabel.backgroundColor = [UIColor greenColor];
firstWordLabel.text = #"Hello";
UIPanGestureRecognizer *gesture = [[UIPanGestureRecognizer alloc]
initWithTarget:self
action:#selector(labelDragged:)];
[holderView addGestureRecognizer:gesture];
firstWordLabel.userInteractionEnabled = YES;
[holderView addSubview:firstWordLabel];
[self.view addSubview:holderView];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self startTheAnimation]; //calling animation
}
- (void)startTheAnimation
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenWidth = screenRect.size.width;
CGRect newRect = firstWordLabel.frame;
newRect.origin.x = floor(screenWidth/2);
[UIView animateWithDuration:20.0f delay:0.0f options:UIViewAnimationOptionAllowUserInteraction animations:^{
firstWordLabel.frame = newRect;
} completion:^(BOOL finished) {
NSLog(#"completed");
}];
}
- (void)labelDragged:(id)sender
{
NSLog(#"Dragged");
}
