Can't load a page in a UIWebView - iphone

Question

I i'm developing a News App that get the content from a rss feed.
When i click on a TableViewCell I pass a NSDictionary object with the title, link, etc to the next ViewController. In the ViewController I define NSDictionary *item; and I can verify that the values are passed correctly by setting the title of the viewcontroller like this: self.title = [item objectForKey:#"link"]; the title shows the link im trying to open in my UIWebView.
Here is my ViewController's implementation
//
// NewsDetailViewController.m
// NewsApp2
//
// Created by Marco Soria on 12/27/10.
// Copyright 2010 __MyCompanyName__. All rights reserved.
//
#import "NewsDetailViewController.h"
#implementation NewsDetailViewController
#synthesize item, itemTitle, itemDate, itemSummary;
-(id)initWithItem:(NSDictionary *)theItem{
if(self = [super initWithNibName:#"NewsDetail" bundle:[NSBundle mainBundle]]){
self.item = theItem;
self.title = [item objectForKey:#"link"];
}
return self;
}
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
/*
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization.
}
return self;
}
*/
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
NSString *urlAddress = [self.item objectForKey:#"link"];
NSURL *baseURL = [[NSURL URLWithString: urlAddress] retain];
NSURLRequest *request = [NSURLRequest requestWithURL:baseURL];
[self.itemSummary loadHTMLString:urlAddress baseURL:nil];
[self.itemSummary loadRequest:request];
[baseURL release];
}
/*
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations.
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
*/
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
#end
Now, when I assign the address like this #"http://somesite.com" the UIWebView loads just fine but when i do this: NSString *urlAddress = [self.item objectForKey:#"link"]; it never loads. As I mentioned i checked that the value of [self.item objectForKey:#"link"]; is a valid url since its displaying it in the title of the navigationbar.
if I do this: [self.itemSummary loadHTMLString:urlAddress baseURL:nil];
the UIWebView displays the url, another way of verifying that urlAddress has the correct url.
What am I doing wrong?

Answer 1

Where do you assign self.title with [item objectForKey:#"link"]?
Have you added item as a property of your view controller in your .h file? If you haven't then in your viewDidLoad method you posted above, you would not have access to self.item.
In your .h file:
#interface MyViewController : UIViewController {
NSDictionary *item;
}
#property (nonatomic, readwrite, retain) NSDictionary *item;
In your .m file (adjust this to suit your init method):
-(id)initWithItem:(NSDictionary *)item {
if (self = [super initWithNibName: nil bundle: nil]) {
self.item = item;
}
return self;
}
After you do that you will have global access in your view controller's methods to the item property via self.item.

It's solved, i did
NSURL *baseURL = [[NSURL URLWithString: [urlAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]] retain];
and works now, apparently I was sending some spaces after the url and that's why it wasn't a valid url even though it apeared valid. I NSLog and got baseUrl http://site.com/item.php?id=2458%20%0A%09%20%20%20%20%20%20%20%20%09%20%20%20%20%09%09%09%09
