open URL in UITextView in a modal view controller
I have a UITextView which has a text combination of some strings and URL. Right now when I click on the URL it opens it up in safari. What I want to do instead is to have it open in a new UIViewController pushed as a modalViewController. There are two problems with this:
- Extracting the URL from the UITextView
- Intercepting the call to safari to open it up and instead push a modalViewController to display it in a webview.
I know it has been done before, for example in the tweetbot app. It opens up the link in a navigation bar where you can go back to the previous view. Something like this is also fine with me. Any pointers on what to do?
It's annoying for a user when you have to open up the link in a browser and you can't go back to the app again.
UPDATE:
I followed the suggestion given in the 开发者_如何学Golink to this post but after changing that my view just changes to a white screen:
#import <Foundation/Foundation.h>
@class CVore;
@protocol CVoreDelegate
- (void) withURL:(NSURL *)url;
@end
@interface CVore : UIApplication {
id <CVoreDelegate> delegate;
}
@property (nonatomic, assign) id <CVoreDelegate> delegate;
@end
#import "CVore.h"
@implementation CVore
@synthesize delegate;
- (BOOL)openURL:(NSURL *)url{
if (url){
[self.delegate withURL:url];
return YES;
}
return NO;
}
@end
