iOS load UIWebView URL from notification - ios

Question

I'm having a strange issue, using Xcode 5 and testing on iOS 7, I'm sending an extra parameter with the apn request named "url", I need to open that URL in the webview when the notification is received, but the app freeze when the notification arrives if it was connected to the USB, or does nothing when is not connected.
AppDelegate.m
#import "AppDelegate.h"
#implementation AppDelegate
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(#"Did Register for Remote Notifications with Device Token (%#)", deviceToken);
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(#"Did Fail to Register for Remote Notifications");
NSLog(#"%#, %#", error, error.localizedDescription);
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Register for Remote Notifications
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
if (launchOptions != nil) {
// Launched from push notification
NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
NSLog(#"Notification received");
[self application:application didReceiveRemoteNotification:(NSDictionary*)notification];
}
return YES;
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if (application.applicationState == UIApplicationStateActive) {
// app was already in the foreground
NSLog(#"app was already in the foreground");
} else {
// app was just brought from background to foreground
NSLog(#"app was just brought from background to foreground");
}
if ([userInfo objectForKey:#"url"])
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"loadNotificationUrl" object:self userInfo:userInfo];
}
}
And that's what is in the ViewerController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *urlString = #"http://example.com/?action=home";
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView loadRequest:urlRequest];
webView.delegate = self;
webView.opaque = NO;
webView=[[UIWebView alloc]init];
[webView setBackgroundColor:[UIColor grayColor]];
[webView setDelegate:(id<UIWebViewDelegate>)self];
[self.view addSubview:webView];
activityIndicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.frame = CGRectMake(200.0, 200.0, 100.0, 40.0);
activityIndicator.center = self.view.center;
[self.view addSubview: activityIndicator];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(loadNotificationUrl:)
name:#"loadNotificationUrl" object:nil];
}
-(void)loadNotificationUrl:(NSNotification*) notification
{
NSDictionary* userInfo = notification.userInfo;
NSString* NotificationUrl = (NSString*)userInfo[#"url"];
NSLog (#"Successfully received: %#", NotificationUrl);
NSURL *url = [NSURL URLWithString:NotificationUrl];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView loadRequest:urlRequest];
}
As my little experience, this should load the URL when the notification is clicked, but it is either freeze or does nothing, can anybody tell me where is my mistake please?
