Hello there, I want to add stroke to UITextView's text in iOS 6.
As iOS 6 add support attributedText to UILabel, UITextField, UITextView, I create a NSMutableAttributedString and set it to UITextView's attributedText. Code is below:
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableAttributedString *title;
title = [[NSMutableAttributedString alloc] initWithString:@"Visual comparison"];
int length = title.length;
[title addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Noteworthy-Bold" size:36] range:NSMakeRange(0,length)];
[title addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,length)];
[title addAttribute:NSStrokeColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,length)];
[title addAttribute:NSStrokeWidthAttributeName value:@-3.0 range:NSMakeRange(0,length)];
UITextView *label = [[UITextView alloc] initWithFrame:self.view.bounds]; label.attributedText = title;
[self.view addSubview:label];
}
But it take no effect, UITextView's text is not stroked or filled. Replace UITextView with UILabel or UITextField everything will be right.
And if you set NSStrokeWidthAttributeName's value to @3.0 and comment one line like this:
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableAttributedString *title;
title = [[NSMutableAttributedString alloc] initWithString:@"Visual comparison"];
int length = title.length;
[title addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Noteworthy-Bold" size:36] range:NSMakeRange(0,length)];
[title addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,length)];
// [title addAttribute:NSStrokeColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,length)];
[title addAttribute:NSStrokeWidthAttributeName value:@3.0 range:NSMakeRange(0,length)];
UITextView *label = [[UITextView alloc] initWithFrame:self.view.bounds]; label.attributedText = title;
[self.view addSubview:label];
}
UITextView's text is stroked exactly.
If you add these lines:
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableAttributedString *title;
title = [[NSMutableAttributedString alloc] initWithString:@"Visual comparison"];
int length = title.length;
[title addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Noteworthy-Bold" size:36] range:NSMakeRange(0,length)];
[title addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,length)];
if (length % 2 == 0)
{
length = length / 2 - 1;
}
else
{
length = length / 2;
}
[title addAttribute:NSStrokeColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,length)];
[title addAttribute:NSStrokeWidthAttributeName value:@-3.0 range:NSMakeRange(0,length)];
UITextView *label = [[UITextView alloc] initWithFrame:self.view.bounds]; label.attributedText = title;
[self.view addSubview:label];
}
and then UITextView's text will be correct again.
Anyone know why?
