All I want is to display some simple text in my viewController and have the hyperlinks autoparsed. When the user clicks on the link I want the control to somehow do a callback where I can do something with the URL. How can I achieve this?
I've already looked through the TTCatalog for hours. I have also tried looking into the source code of three20 as well as looking at the stack trace. No help. I just can't figure out how my app can react to the click of the URL. Any hints please?
Hard to help without seeing what you've already tried, but you should be able to do something like the following:
TTStyledTextLabel* label = [[[TTStyledTextLabel alloc]
initWithFrame:someFrame] autorelease];
NSString* labelText = #"This should work";
label.text = [TTStyledText textFromXHTML:labelText lineBreaks:NO URLs:YES];
[someView addSubview:label];
You can then use TTNavigator and TTURLMap to map custom-uri://some/url to a particular controller in your application, or handle it yourself in your application delegate. The best place to find out how to do that is by looking at the TTNavigatorDemo sample application included in the Three20 source. Specifically, look at AppDelegate.m which is where all the URL mapping gets performed.
In addition to what Nathan says about URL mapping and links, you can also use CSS styles!
TTStyledTextLabel* label = [[[TTStyledTextLabel alloc] initWithFrame:someFrame] autorelease];
NSString* labelText = #"This should work and
<span class=\"redText\">this should be red</span>";
label.text = [TTStyledText textFromXHTML:labelText lineBreaks:NO URLs:YES];
[someView addSubview:label];
Then in your StyleSheet.m implement
- (TTStyle*) redText {
return [TTTextStyle styleWithFont:[UIFont systemFontOfSize:12] color:RGBCOLOR(255,0,0) next:nil];
}

How can I customise the badge number on UITabBarItem?
Something like this
Have a Look at MKNumberBadgeView. Its a little Class for your Custom BadgeView.
Using it like this I am able to add it to my custom UITabBarController:
MKNumberBadgeView *badge = [[MKNumberBadgeView alloc] initWithFrame:CGRectMake(110, self.view.frame.size.height-20, 30, 30)];
badge.value = 12;
UIWindow *window = [[UIApplication sharedApplication].windows objectAtIndex:0];
[[[window subviews] objectAtIndex:0] addSubview:badge];
Wich will look like this:
Of course you have to take care of rotating issues when adding the badgeView to the window.
But I guess you can customize MKNumberBadgeView to make it look the way you want it, give it a try.
I have an app where the users enters information in a few textfields which are then added to a uitextview by a nsstring does anybody know how i can set one of the textfields to italics and keep the others normal
regards
Edit:
Heres my code i want to only change once textfield (e.g textfbookpublisher):
NSString* combinedString = [NSString stringWithFormat:
#"%#,%#.'%#.'%#.%#,%#.",
textfbookpublisher.text,
textfbookauthor.text,
textfbooktitle.text,
textfbookplace.text,
nameofuni.text,
textfbookyear.text];
DissertationGen*bookg = [[DissertationGen alloc] init];
bookg.message = combinedString;
bookg.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:bookg animated:YES]
A quick search would have given you an easy answer. For example, this post.
Simply set the font of the UITextfield you want to a [UIFont italicSystemFontOfSize:].
try this link see accepted answer and also check TTTAttributedLabel library
Bold one Word
now you want only textfbookpublisher in italic then pass it individually to next DissertationGen view
in DissertationGen controller's viewdidload method use following code
UILabel *lblpubl = [[UILabel alloc] init];
lblpubl.font = [UIFont italicSystemFontOfSize:18.0];
lblpubl.text = your variable which contains textfbookpublisher's text;
now use lblpubl as you wish
I'm trying to show in my app something like this:
Liked by #user1, #user2 and 3 more.
Many apps have this format either for comments like who posted it and their comment,
example: #me yeah apples are good
When you tap their name, it takes you somewhere in the app.
I would like #user1 #user2 and 3 more to be clickable and perform a selector.
I would also like them to be bold and a certain color.
UIWebView can stylize text but can I perform selectors by touching part of an attributed string?
I have been trying to find the best way to do this without making labels and buttons and calculating them dynamically by the length of each username like this:
Label = "Liked by "
Button = "#user1"
Label ", "
Button = "#user2"
Label "and "
Button "3 more"
Label "."
There must be a better way!
Thanks in advance.
You'd be better with an inline UIWebView -- provided you don't need to add this to a scroll view. You can detect actions/link clicks inside a webview by registering some delegate for them and then giving fake protocols/URLs as the link URL. Something like this:
UIWebView *wv = [[UIWebView alloc] initWithFrame:aFrame];
wv.delegate = self;
[wv loadHTMLString:#"<a href='userlike:user1'>#user1</a> hates this." baseURL:nil ]; // further parts of this method name omitted
// because it's long, look it up in UIWebView class reference.
[self.view addSubview:vw];
[wv release];
And the delegate method:
- (BOOL)webView:(UIWebView *)wv shouldStartLoadWithRequest:(NSURLRequest *)rq navigationType:(UIWebViewNavigationType)type
{
if ([[[rq URL] protocol] isEqualToString:#"userlike"])
{
NSString *userName = [[rq URL] host];
// extract username from the URL, then
return NO;
}
// else
return YES;
}
EDIT: I found this, exactly what you're looking for. (as it turns out, #regan also suggested the exact same thing.)
You can call selectors from the HTML code, see for example here and here.
I ran into difficulties with SSCollectionView and SSCollectionViewItem.
First of all I'd like to get it initialized from IB. But that won't work for me.
I have a SelectFooViewController which is:
#interface SelectFooViewController : SSCollectionViewController { ... }
and am using it as filesOwner of the corresponding XIB.
SelectFooViewController* selectFooVC = [[SelectFooViewController alloc]
initWithNibName:#"SelectFooViewController" bundle:nil];
But since it wont work I had to initialize its properties inside viewDidLoad() myself.
Furthermore I am not able to display anything except the backgroundColor of my SSCollectionViewItems. What I want is a textLabel and an image .
- (SSCollectionViewItem *)collectionView:(SSCollectionView *)aCollectionView itemForIndexPath:(NSIndexPath *)indexPath {
SSCollectionViewItem *item = [[[SSCollectionViewItem alloc] initWithStyle:SSCollectionViewItemStyleImage reuseIdentifier:itemIdentifier] autorelease];
SSLabel* label = [[SSLabel alloc] init];
[label setText:#"foo"];
item.imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"foo.png"]];
item.textLabel = label;
[label autorelease];
return item;
}
I can confirm that the delegate methods (for determining the number Of rows, sections and such) are implemented and working as expected. But my items are all empty - but react onclick with the expected popup.
Does anyone see an error in what I did? - Thanks...
EDIT: I was also not able to display a local image by changing SSCatalog project
I just figured out, that I have to set the frame of each property (textLabel, detailTextLabel and imageView) myself. That fixed it.
When you create instance SelectFooViewController just insert this line
selectFooVC.view;
or
selectFooVC.view.hidden = NO;
And then add it to the view.
This is because the view is not initalised until you explicitly access it. Hence your items are loaded only when you click it and not immediately. You can call it a hack but i don't call it one. :-)
I'm trying to get this control to work with a hypertext link with not much success. I have looked at TTCalaog and tried to replecate but does not work.
I have this working as far as displaying the hypertext link but it does not fire.
TTStyledTextLabel* label = [[[TTStyledTextLabel alloc] initWithFrame:CGRectMake(5, 0, 315, 175)] autorelease];
NSString* labelText = #"This should work";
label.text = [TTStyledText textFromXHTML:labelText lineBreaks:NO URLs:YES];
[self.view addSubview:label];
I thing I am missing the point here perhaps with the placement of the google url? I have seen a post on this forum that makes use of custom-uri://some/url that is then set up in TTURLMap and TTNavigator, but I need to open a url from the hypertext in a webview so I need the url to run a method in my class that creates my webview controller etc.
I have tried to cusomise TTURLMap to work without a TTNavigator but completely pickled?
Any help gratefullt appreciated ;-)
Thanks
I've just found myself a solution to catch the clicked URL on a TTStyledTextLabel. I hope this could help in your case too.
This's what I have done.
1. Create TTNavigator
TTNavigator *navigator = [TTNavigator navigator];
navigator.persistenceMode = TTNavigatorPersistenceModeNone;
navigator.delegate = self;
2. Create TTNavigatorDelegate
As you assigned self as delegate of the navigator object. Therefore, please remember to add protocol in the header file .h before you continue.
In the implementation, create this method
- (BOOL) navigator:(TTBaseNavigator *)navigator shouldOpenURL:(NSURL *)URL {
// Now you can catch the clicked URL, and can do whatever with it
// For Example: In my case, I take the query of the URL
// If no query is available, let the app open the URL in Safari
// If there's query, get its value and process within the app
NSString *query = URL.query;
if (query == nil) {
return YES;
} else {
// process the query
}
}
I hope this helps! Please vote for me if this helps to solve your issue!
