How to detect which UILabel was tapped?

Question

I have three UILabels. I want to detect which label is Tapped, and then retrieve the string value of that label. this is how I am trying, I could only manage to detect tapped position, But I couldn't detect which label was tapped.

Label Creation

for (NSInteger i=1; i<=[pdfs count]; i++){
    UILabel *newLabel=[[UILabel alloc] init];
    newLabel.text = [NSString stringWithFormat:[[pdfs objectAtIndex:(i-1)] lastPathComponent]];
    newLabel.frame = CGRectMake(10, 60*i, 320, 20);
    newLabel.tag=i;
    newLabel.font = [UIFont systemFontOfSize:20.0f];
    newLabel.backgroundColor = [UIColor clearColor];
    newLabel.userInteractionEnabled = YES;
    [self.view addSubview:newLabel];
    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    [newLabel addGestureRecognizer:singleTap]; 
    [newLabel release], newLabel=nil;
    [singleTap release];
} 

Detect Taps

 - (void)handleSingleTap:(UITapGestureRecognizer *)recognizer

{

CGPoint location;
location = [recognizer locationInView:self.view];

NSString *documentName;
if(location.y<150.0){
    documentName = [[pdfs objectAtIndex:0] lastPathComponent]; 
}
else{
    documentName = [[pdfs objectAtIndex:1] lastPathComponent]; 
}

UIGestureRecognizer has a reference to a view it is attached to, so you can get your label's tag from it:

int touchedtag = recognizer.view.tag;
documentName = [[pdfs objectAtIndex:touchedtag-1] lastPathComponent];
