UITextView中的发光效果

Question

Can glow effects be applied on text inside UITextView? If so, how?

Answer 1

Here is some code to add a red glow to a UITextView. Requires iOS 6+. Adjust parameters to taste:

NSShadow *shadow         = [NSShadow new];
shadow.shadowBlurRadius  = 5;
shadow.shadowColor       = [UIColor redColor];
shadow.shadowOffset      = CGSizeMake(0, 0);

NSDictionary *attributes = @{NSShadowAttributeName:shadow};

textView.attributedText  = [[NSAttributedString alloc]
                                        initWithString:title
                                            attributes:attributes];

Answer 2

Not really. You might be able to use a CSS-styled (using the text-shadow property) <textarea> in a UIWebView , though.
