Question

My app has a method that creates a label

     -(void)addLabel:(float)x:(float)y:(float)w:(float)h:(NSString *)text {
        CGRect label1Frame = CGRectMake( x, y, w, h );
        UILabel *label1 = [[UILabel alloc] initWithFrame: label1Frame];
        label1.text = text;
        [self.view addSubview:label1];}

Then I call this method from other methods.

How can I access one of these labels to remove it from the superview, as I don’t have an var name for it.

Answer 1

-(void)addLabel:(float)x :(float)y :(float)w :(float)h :(NSString *)text tag:(NSInteger)tag {
    CGRect label1Frame = CGRectMake( x, y, w, h );
    UILabel *label1 = [[UILabel alloc] initWithFrame: label1Frame];
    label1.tag = tag;
    label1.text = text;
    [self.view addSubview:label1];
}

Then pass in an appropriate tag value (an integer) which is unique. Then use:

UILabel *label = (UILabel *)[self.view viewWithTag:someIntID];

to access it.
