Question

I want to achieve something like this inside a UIView:

I have created a custom UILabel with a custom init method:

@implementation TagLabel
- (id)init {
    self = [super initWithFrame:CGRectMake(0, 0, 100, 40)];
    if (self) {
        self.layer.borderColor = [UIColor whiteColor].CGColor;
        self.layer.borderWidth = 4.0;
        self.layer.cornerRadius = 4;
        self.backgroundColor = [UIColor greenColor];
        self.textColor = [UIColor whiteColor];
        self.textAlignment = UITextAlignmentCenter;
    }
    return self;
}
@end

And I create and add each label to the view like so:

for (NSDictionary *tag in [self.voicenote objectForKey:@"Tag"]) {
        TagLabel *tagLabel = [[TagLabel alloc] init];
        tagLabel.text = [tag objectForKey:@"tag"];
        [self.tagsView addSubview:tagLabel];
    }

Yet all I get is a blank UIView, am I missing something? Would there be a better way to achieve this?

EDIT: one problem solved, modified the UILabel code to set the background color directly to the background, and now they show, now how can I make them be one beside the other and not overlapped?

In your for loop, you need to make custom frames for your labels and arrange them the way you want.
something like this maybe:

CGRect frame = label.frame;
frame.size.height = masterFrame.height;
frame.origin.y = masterFrame.origin.y + masterFrame.size.height + 40;
label.frame = frame;

This is a longer way to do it. You could also just initialize the frame with [CGRect initWithFrame …]
