Question

I have a UILabel whose text I am getting from a server. Some of the text is to be identified as links, and on touching those links some action should be performed. e.g.

NSString *str = @“My Telephone number is 645-345-2345 ,我的地址是 xyz;

This is the complete text for UILabel. I have only one UILabel for displaying this text (Text is dynamic. I just gave an example.). On clicking these links I need to perform actions like navigating to some different screen or make a call.
I know that I can display such text with help of OHAttributedLabel. And the links can be displayed as follows :

[label1 addCustomLink:[NSURL URLWithString:@"http://www.foodreporter.net"] inRange:[txt rangeOfString:someString]];

But I wonder how can I make these text links perform some action like navigation to different screen or making a call.
Let me know if more explanation is required.

Answer 1

您可在的任何现有代号上添加习俗行动,支持使用fake/em>URL计划的链接,然后拦截:

TTTAttributedLabel *tttLabel = <# create the label here #>; NSString *labelText = @"Lost? Learn more."; tttLabel.text = labelText; NSRange r = [labelText rangeOfString:@"Learn more"]; [tttLabel addLinkToURL:[NSURL URLWithString:@"action://show-help"] withRange:r];

随后,在<条码>中,TTTAttributed LaborelDelegate:

- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url { if ([[url scheme] hasPrefix:@"action"]) { if ([[url host] hasPrefix:@"show-help"]) { /* load help screen */ } else if ([[url host] hasPrefix:@"show-settings"]) { /* load settings screen */ } } else { /* deal with http links here */ } }

TTTAttributedLabel 是公共卫生和社会福利部的一个论坛。

如果你想采取更为复杂的办法,请上。它支持海关连接外箱。

Answer 2

You can use UITextView with Phone numbers and links detection YES, scrolling disabled YES user interaction enabled YES, instead of UILabel.

Answer 3

我的项目成功地利用了OHAttributedLabel。检查

-(BOOL)attributedLabel:(OHAttributedLabel*)attributedLabel shouldFollowLink:(NSTextCheckingResult*)linkInfo;

link。它允许你决定点击链接发生什么。如果看,则用于显示警示。如果你回到<代码>NO,就本案(为了保持不发生违约行动)的话,你只能做你想要的导航等。

但请注意,这要求你能够正确从案文中确定行动。就我们的项目而言,我们采用了一种稍微狂热的解决方案,服务器把我们的文本寄给给他们中间的对口单位,并用一份指挥清单为每个对面。

Answer 4

There a project called FancyLabel that is about what you need. It might need some customization though. Also, I think Three20 has this functionality, but it might be an overkill if you don t already use it.

还有一个更为简单的解决办法,如果你的所有联系都是电话地址。你们只能使用UITextView,而不是“IDLabel”。它自动探测电话、地址等。 (正确检查IB中的箱子)

如以下解释,你也可以采取习俗行动,以点击有关这些联系的事件:here

Is there a specific reason that you must use a UILabel instead of a UITextView? Note that a lot of the implementations of attributed labels inherit from UIView or don t implement all of UILabel s functionality.

Answer 5

你们可以利用习俗纽扣来看待联系。如果你打算使用纽芬兰语,你也可以在习俗标签上添加姿态。

UITapGestureRecognizer* gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(userTappedOnLink:)];
// if labelView is not set userInteractionEnabled, you must do so
[labelView setUserInteractionEnabled:YES];
[labelView addGestureRecognizer:gesture];

Answer 6

当我需要一个轻重标签,使连接起来时,我不会被迫使用<条码>UITextView或第三方的校正(当我重新开发时告诉我!)

Here s my attempt at a lightweight UILabel subclass able to detect link taps. The approach is different from others I ve seen in that it gains access to the UILabel s shared NSLayoutManager via a delegate callback added to NSTextStorage via a category extension. The beauty is that UILabel performs its native layout and drawing - other UILabel replacements often augment or replace the native behavior with an additional NSLayoutManager/NSTextContainer.

Probably App Store safe, but somewhat fragile - use at your own risk!
