Question

I found this little snippet which allows one to create links from text in an NSTextView:

-(void)setHyperlinkWithTextView:(NSTextView*)inTextView
{
    // create the attributed string
    NSMutableAttributedString *string = [[NSMutableAttributedString alloc] init];

    // create the url and use it for our attributed string
    NSURL* url = [NSURL URLWithString: @"http://www.apple.com"];
    [string appendAttributedString:[NSAttributedString hyperlinkFromString:@"Apple Computer" withURL:url]];

    // apply it to the NSTextView s text storage
    [[inTextView textStorage] setAttributedString: string];
}

在我的申请中,能否把链接点与某些资源联系起来,例如与能够解释联系和向相应观点/控制者发送的具体手递类别联系起来?

可以通过执行。方法。

如果你需要把更多的信息储存在每一个环节上,那么你就可以这样做,把物体储存起来,作为显示与链接的习惯特性:

NSDictionary* attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                            yourObject, @"YourCustomAttributeName",
                            @"link", NSLinkAttributeName,
                            nil];
NSAttributedString* string = [[[NSAttributedString alloc] initWithString:@"Your string" attributes:attributes] autorelease];

• 确保你收回所描述的以下文字: <代码>NSCoding protocol ,而不是“RTF”方法:NSAttributedString,因为RTF不能储存习俗属性。
