无法使用TTTAttributedLabel框架

Question

我正在使用TTTAttributedLabel来制作UILabel超链接，我尝试如下所示：

 NSAttributedString *attString = [[NSAttributedString alloc] initWithString:@"By tapping you agree to the Terms of Use and Privacy Policy."
                attributes:@{
            (id)kCTForegroundColorAttributeName : (id)[UIColor redColor].CGColor,
                                                                                 NSFontAttributeName : [UIFont boldSystemFontOfSize:16],
                                                                                 NSKernAttributeName : [NSNull null],
                                                                                 (id)kTTTBackgroundFillColorAttributeName : (id)[UIColor greenColor].CGColor
                                                                                 }];

// The attributed string is directly set, without inheriting any other text
// properties of the label.
self.tttTermAndCondition.text = attString;
self.tttTermAndCondition.delegate = self; // Delegate methods are called when the user taps on a link (see `TTTAttributedLabelDelegate` protocol)

//self.tttTermAndCondition.text = @"Fork me on GitHub! (http://github.com/mattt/TTTAttributedLabel/)"; // Repository URL will be automatically detected and linked
self.tttTermAndCondition.enabledTextCheckingTypes = NSTextCheckingTypeLink;
NSRange range = [self.tttTermAndCondition.text rangeOfString:@"Terms of Use"];
[self.tttTermAndCondition addLinkToURL:[NSURL URLWithString:@"http://github.com/mattt/"] withRange:range];

这显示得非常好，但当我单击使用术语时，

TTTAtributedLabel在它的- (NSArray *) links方法中崩溃，它成为一个僵尸对象。

我不知道我到底错过了什么。

提前谢谢。

您好，我将您的代码放在我的示例应用程序中，它可以很好地工作，只需添加委托方法，您的代码就可以正常工作

- (void)viewDidLoad {
[super viewDidLoad];
tttTermAndCondition = [[TTTAttributedLabel alloc]initWithFrame:CGRectMake(0, 50, 320, 200)];
NSAttributedString *attString = [[NSAttributedString alloc] initWithString:@"By tapping you agree to the Terms of Use and Privacy Policy."
                                                                attributes:@{
                                                                             (id)kCTForegroundColorAttributeName : (id)[UIColor redColor].CGColor,
                                                                             NSFontAttributeName : [UIFont boldSystemFontOfSize:16],
                                                                             NSKernAttributeName : [NSNull null],
                                                                             (id)kTTTBackgroundFillColorAttributeName : (id)[UIColor greenColor].CGColor
                                                                             }];

// The attributed string is directly set, without inheriting any other text
// properties of the label.
tttTermAndCondition.text = attString;
tttTermAndCondition.delegate = self; // Delegate methods are called when the user taps on a link (see `TTTAttributedLabelDelegate` protocol)

//self.tttTermAndCondition.text = @"Fork me on GitHub! (http://github.com/mattt/TTTAttributedLabel/)"; // Repository URL will be automatically detected and linked
tttTermAndCondition.enabledTextCheckingTypes = NSTextCheckingTypeLink;
NSRange range = [tttTermAndCondition.text rangeOfString:@"Terms of Use"];
[tttTermAndCondition addLinkToURL:[NSURL URLWithString:@"http://github.com/mattt/"] withRange:range];
//self.se
[self.view addSubview:tttTermAndCondition];
// Do any additional setup after loading the view, typically from a nib.
}


-(void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url
{
    [[UIApplication sharedApplication] openURL:url options:nil completionHandler:nil];
}
