Drawing colored text in UIView's -drawRect: method

Question

I am trying to draw colored text in my UIView subclass. Right now I am using the Single View app template (for testing). There are no modifications except the drawRect: method.

The text is drawn but it is always black no matter what I set the color to.

- (void)drawRect:(CGRect)rect {     UIFont* font = [UIFont fontWithName:@"Arial" size:72];     UIColor* textColor = [UIColor redColor];     NSDictionary* stringAttrs = @{ UITextAttributeFont : font, UITextAttributeTextColor : textColor };      NSAttributedString* attrStr = [[NSAttributedString alloc] initWithString:@"Hello" attributes:stringAttrs];      [attrStr drawAtPoint:CGPointMake(10.f, 10.f)]; } 

I've also tried [[UIColor redColor] set] to no avail.

Answer:

NSDictionary* stringAttrs = @{ NSFontAttributeName : font, NSForegroundColorAttributeName : textColor };

Answer 1

Instead of UITextAttributeTextColor you should use NSForegroundColorAttributeName. Hope this helps!

Answer 2

You can try with following methods. It will help you to draw text in UIView at the bottom right corner with the help of following attributes.

• NSFontAttributeName - Font name with size
• NSStrokeWidthAttributeName - Stroke Width
• NSStrokeColorAttributeName - Text Color

Objective-C - Draw text in the UIView and return as UIImage.

    -(UIImage *) imageWithView:(UIView *)view text:(NSString *)text {          UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);          [view.layer renderInContext:UIGraphicsGetCurrentContext()];          // Setup the font specific variables         NSDictionary *attributes = @{                 NSFontAttributeName   : [UIFont fontWithName:@"Helvetica" size:12],                 NSStrokeWidthAttributeName    : @(0),                  NSStrokeColorAttributeName    : [UIColor blackColor]         };         // Draw text with CGPoint and attributes         [text drawAtPoint:CGPointMake(view.frame.origin.x+10 , view.frame.size.height-25) withAttributes:attributes];          UIImage * img = UIGraphicsGetImageFromCurrentImageContext();         UIGraphicsEndImageContext();          return img;     }` 

Swift - Draw text in the UIView and return as UIImage.

    func imageWithView(view : UIView, text : NSString) -> UIImage {          UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);         view.layer.renderInContext(UIGraphicsGetCurrentContext()!);         // Setup the font specific variables         let attributes :[String:AnyObject] = [             NSFontAttributeName : UIFont(name: "Helvetica", size: 12)!,             NSStrokeWidthAttributeName : 0,             NSForegroundColorAttributeName : UIColor.blackColor()         ]         // Draw text with CGPoint and attributes         text.drawAtPoint(CGPointMake(view.frame.origin.x+10, view.frame.size.height-25), withAttributes: attributes);         let img:UIImage = UIGraphicsGetImageFromCurrentImageContext();          UIGraphicsEndImageContext();         return img;     }`
