uilabel with outline or stroke [duplicate]

Question

I was wondering how can I create text stroke for UILabel ? is there any possible way ?

thank you ,

#import <Foundation/Foundation.h>


@interface CustomLabel : UILabel {

 }

 @end

#import "CustomLabel.h"


@implementation CustomLabel

- (void)drawTextInRect:(CGRect)rect {

    CGSize shadowOffset = self.shadowOffset;
    UIColor *textColor = self.textColor;

    CGContextRef c = UIGraphicsGetCurrentContext();
    CGContextSetLineWidth(c, 22);

    CGContextSetTextDrawingMode(c, kCGTextStroke);
    self.textColor = [UIColor whiteColor];
    [super drawTextInRect:rect];

    CGContextSetTextDrawingMode(c, kCGTextFill);
    self.textColor = textColor;
    self.shadowOffset = CGSizeMake(0, 0);
    [super drawTextInRect:rect];

    self.shadowOffset = shadowOffset;
    //works fine with no warning 
}   

now the question is how can i use this subclass with a IBOutlet label on different viewcontrollers . is it right :

    label = [[CustomLabel alloc] initWithFrame:CGRectMake(0, 0, 190, 190)];

Answer 1

It may be helpful to some to add that depending on font and characters, adding:

CGContextSetLineJoin(c,kCGLineJoinRound);

can prevent artifacts from too large a stroke applied to too sharp a character.
