This is my code, whenever I click the link didSelectLinkWithURL delegate is not getting called. Any help is appreciated.
TTTAttributedLabel *tttLabel = [[TTTAttributedLabel alloc]initWithFrame:CGRectMake(10, 10, 200, 200)];
NSString *labelText = @"Lost? Learn more.";

[self.view addSubview:tttLabel];
tttLabel.userInteractionEnabled=YES;
- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url {
UIWebView *web=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

}
推荐答案
确保您的类实现了TTTAttributedLabelProtocol，并设置了tttLabel.delegate = self;在头文件中:
Make sure your class implements TTTAttributedLabelProtocol, and set tttLabel.delegate = self;In the header file:
@interface yourClass : parentClass <TTTAttributedLabelDelegate> {
}
在实施文件中
TTTAttributedLabel *tttLabel = [[TTTAttributedLabel alloc]initWithFrame:CGRectMake(10, 10, 200, 200)];
tttLabel.delegate = self;
NSString *labelText = @"Lost? Learn more.";
tttLabel.text = labelText;
NSRange r = [labelText rangeOfString:@"Learn more"];
[tttLabel addLinkToURL:[NSURL URLWithString:@"action://show-help"] withRange:r];
[self.view addSubview:tttLabel];
tttLabel.userInteractionEnabled=YES;
- (void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url {
NSLog(@"Did click");
}
