How can I get the latitude and longtitude from mapView.userLocation?
I need that to get the distance between userLocation and another point on the map.
I hope you can help me and thank you beforehand!
Use the method provided in CLLocation:
- (CLLocationDistance)getDistanceFrom:(const CLLocation *)location

I've developed an iPhone application to parse data from an XML file. This data contains a set of longitudes and latitudes for different places.
How do I detect nearest of them according to my current location on the map and how do I set set a range to show places in this range?
CLLocation *myLocation = [[CLLocation alloc] initWithLatitude:myLatitude longitude:myLongitude];
CLLocation *myXmlLocation = [[CLLocation alloc] initWithLatitude:xmlLatitude longitude:xmlLongitude];
CLLocationDistance distance = [myLocation distanceFromLocation: myXmlLocation];
This is in meters, so you must do any converting from there. They are also linear, so these aren't driving direction lengths by any means. Good luck.
some trig, but really not too difficult.
this page has an example script, not in your language, but it contains explainations and the equations you need.

and also, please don't write run-on sentences, it took me a while to read your question.
#Vinnie said is absolutely right but these values is air distance.
Also this method is deprecated in iOS 3.2
- (CLLocationDistance)getDistanceFrom:(const CLLocation *)location Parameters
You can't find the distance based on roads with the Apple SDK. Try to use google APIs for finding distance between two points on earth on roads.
Hello I am creating travel app. I want to find current location and find the distance between selected hotel or place from this location.. I searched core location but it is not returning longitude and latitude of current location in simulator .please help me and how can I calculate distance ?
To calculate distances you can use the distanceFromLocation: method of the CLLocation class.
I'm trying to calculate the distance between two places user Core Location. I've found a few posts that state to use
-(CLLocationDistance)distanceFromLocation:(const CLLocation *)location
Found some other test code in the thread below:
CLLocationDistance NaN
I'm not sure how to put it all together, to get the result I want ?
Anyone any thoughts ?

If you have a location named myLocation and want to find the distance from another location, say, restaurantLocation, then it seems you would do something like
CLLocationDistance distance = [myLocation distanceFromLocation:restaurantLocation]
This will give you the distance, in meters, between the two.
Can anyone help me "How to calculate distance between two places in MAP(CLLocation).Tell the delegates,methods etc to be used .
Thanks in advance,

Does this help?
distanceFromLocation - Calculate distance between two points
You can use this method in CLLocation that takes another CLLocation object and returns the distance in meters:
- (CLLocationDistance)distanceFromLocation:(const CLLocation *)location
Be aware that it's available only in iOS ≥3.2. If you wanna target older iOS versions, use
- (CLLocationDistance)getDistanceFrom:(const CLLocation *)location
This method is marked as deprecated and will disappear at some time in the future.
i am implementing an app, that show customers and my userLocation on a map.
But now i have a problem, because there are a lot of costumers and the map is very uncomfortable.
How can i only see pins on a map or in a list, that are around 100 kilometers away from
me?
I hope someone could help me?
Greetings Marco
you should cache your current location in a CLLocation* variable.
You have to calculate the distance of every pin (annotation) you add from this location using [myLoc getDistanceFrom:pinLoc] which returns a CLLocationDistance i believe. If this is > 100 kms don't add it to your map.
