I want to use the LinkedIn API in my project, but I haven't found any good tutorials about using LinkedIn API. How to use LinkedIn API? "A beginners guide/introduction" of "basic concepts" would be helpful. OK, after googleing around I went to this link LinkedInAPI . I filled in the form but I am unable to understand what the "Integration URL" (Example URL where the integration will go live.) Because I want to use LinkedIn in native iPhone application not on any website? So after getting keys how do I use those keys and how do I authenticate user and get some profile info,post status like all

I'm using MapKit on iPhone. How can I know when the user changes the zoom level (zoom in\out the map)? I've tried to use mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated; but that's called even when the map is only dragged. Unfortunately, when the map is dragged the mapView.region.span changes as well... Help? 10x afarnham It is pretty simple to calculate the zoom level. See the snippet below. You can get the mRect parameter from the visibleMapRect property on your MKMapView instance. + (NSUInteger)zoomLevelForMapRect:(MKMapRect)mRect withMapViewSizeInPixels:(CGSize

I have a date converted to double value and saved in database. Now, I want to compare if currentDate > myDataBaseDate + 8 hours i.e., I want to get 8 hours added to myDataBaseDate. I'm converting date into double values. So how do I get 8 hours later time from my database saved date. How do I compare if (currentDateTime > DateFromdatabaseValue + DateByAdding8HoursInDataBase) Tom Jefferys I'm not entirely sure what you are trying to do, but you can create an NSDate object by adding time in seconds on to another NSDate using: - (id)dateByAddingTimeInterval:(NSTimeInterval)seconds // eg. to add 8

I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar.
