Display attributed text of UILabel in UIView

Question

So I'm trying to get attributed text with various colors to display on a UIView . My variables are

NSMutableAttributedString *myString ;

UILabel *myLabel;

UIView *myView;

First, I did the following in order to assign myLabel's attributedText to myString

[myLabel setAttributedText: myString];

Now I'm not entirely sure how to add myLabel to myView in order to make it so that the attributed text shows up. It seems that UIView's acknowledge UILabel textfields but not attributedtextfields

Answer 1

I don't think it makes a difference for the view if you are adding a label with attributed string or regular string. You just addSubview:MyLabel
Check out the code bellow.

//setup the testview
    UIView *testView = [[UIView alloc]initWithFrame:CGRectMake(10, 10, 100, 100)];
    [testView setBackgroundColor:[UIColor blackColor]];
    [self.view addSubview:testView];

    //setup the label
    UILabel *txtLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
    [txtLabel setBackgroundColor:[UIColor redColor]];
    NSDictionary *attrib = @{NSForegroundColorAttributeName : [UIColor blueColor]};
    NSMutableAttributedString *attribString = [[NSMutableAttributedString alloc]initWithString:@"test" attributes:attrib];
    txtLabel.attributedText = attribString;
    [testView addSubview:txtLabel]; //add the label to the testview

You need to addSubview BEFORE applying attributedText to UILabel

let text = NSMutableAttributedString()
text.append(NSAttributedString(string: "AAA", attributes: [NSFontAttributeName: UIFont.systemFont(ofSize: 20)]))
text.append(NSAttributedString(string: "bbb", attributes: [NSFontAttributeName: UIFont.systemFont(ofSize: 10)]))

let label = UILabel()

view.addSubview(label)

label.attributedText = text
label.sizeToFit()

if you move view.addSubview(label) after label.attributedText = text, this label will show same attributes for all text
