First of all, congratulations for sharing this great video tutorial. Let me just make the following correction because "locationServicesEnabled" changed from a property to a method for iOS3 to iOS4. So, instead of ... if (self.locationManager.location­ServicesEnabled) { ...

}

now we must use this code: ... if ([CLLocationManager locationServicesEnabled]) { ... }

Again congratulations and thanks for sharing

Hi, I do this ma it doesn't work.

After the alert that ask me if I want the application uses geolocation (I say OK) it doesn't work. No latitude value and no longitude value. And the user location doesn't work.

Why this?

Great video. The more people out there developing geolocation technology, the better our individual leaps and bounds will be.

@ferreiramanuelvitor Would you please reply the full WhereAmIAppDelegate?

I am a new user and I am trying to understand what´s going in Xcode 4.

It have a problem at:

-(void) locationManager section,

the program does not recognize newLocation and oldLocation arguments.

I got the messages:

1) invalid argument type void to unary expression 'newLocation'

2) use of undeclared identifier

@nullality did you saved the .h file ?

Hello,

first thank you for the great tutorial. Second, I'd like to ask something: I don't get the values for the latitude and longitude written in the labels. I've seen that somebody else also got the same problem too. I've added the two frameworks at the beginning: CoreLocation.Framework and the MapKit.Framework. It is probably something because of the change from iOS3 to iOS4. Can somebody help me out here? Thank you guys!

After I go to File's Owner I try to delegate the latitude / longitude outlets to the blank label fields, but the only thing it will "SEE" is Mapview. WTFMATE?

So much for "Learning" You don't seem to explain anything really, you just tell me what to do. You also talk fast and mumble a bit when you're giving orders on what to do, I wish there was a script available as I do not wish to buy or steal the book in your description (or for that matter continue re-re-re-re-reviewing the same 2 second area trying to figure out why I'm watching a video instead of just reading a script or tutorial)

hello , can you post a tuturial about "how to share location with discription,photo and email"?"

[pro7ron]

Thank you for posting this, I think the most helpful bit is when things go wrong, like the app delegate. It gets experienced programmers, that are new to the language, in the right debugging mindset.

I think the first thing you need to do is learn to upload in higher quality. Fonts should use 720p+
