TTNavigator not opening URLs when clicking on links in TTStyledTextLabels
Trying to make a simple link clicking activity work. I think I understand TTNavigator and 开发者_如何学JAVATTStyledLabel, but can't get it to work.
Code:
@interface SomeVc : UIViewController <TTNavigatorDelegate> {
IBOutlet TTStyledTextLabel *styledTextLabel;
}
@end
@implementation SomeVc
- (void)viewDidLoad {
[super viewDidLoad];
navigator = [TTNavigator navigator];
navigator.persistenceMode = TTNavigatorPersistenceModeNone;
navigator.delegate = self;
TTURLMap* map = navigator.URLMap;
[map from:@"*" toViewController:[TTWebController class]];
styledTextLabel.text = [TTStyledText textWithURLs:someText];
[navigator openURLAction:[TTURLAction actionWithURLPath:@"http://www.cnn.com/"]];
}
- (BOOL)navigator: (TTNavigator*)navigator shouldOpenURL: (NSURL*)URL {
NSLog(@"trying to open %@", [URL absoluteString]);
return NO;
}
@end
I.e inside a viewcontroller, get the navigator and set self to be its delegate. When a link is opened, the shouldOpenURL delgate method gets called, where I will handle the URL opening myself. (I plan to let navigator handle more of it, but want to get this simple case working first.)
I have a test call at the end of viewDidLoad: which fires the delegate method fine.
Problem: I see the styledTextLabels rendered fine with URL-s, but when I tap on those, nothing happens. They don't reach the TTNavigator for some reason and I can't understand why. Feels like I'm missing some simple connection/scaffolding somewhere, but can't figure it out.
How to make it so that the links tapped in the styledtextlabel will reach the navigator delegate? Or how else should I implement this simple case with styledtextlabel? (just want to get callbacks for url taps.)
try setting the window property :
TTNavigator* navigator = [TTNavigator navigator];
navigator.window = window;
If you don't have one you can add one
navigator.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]
You might also need:
[navigator.window makeKeyAndVisible];
