I am developing a app that is going to use a map. I was wondering how to load all the POIs that already appear on the default Apple's map app?
Cheers
There's at least no built in functionality in MapKit. You'll have to use Google's webservices to fetch those POIs (like Places API). You should have a look at the Google Places API Web Services!
I'm not sure why your question was voted down, I guess you need to do some self-research before posting any questions. A lot of times, similar questions have been asked. You just need to look.
Hope this helps.

How do you implement suggestions when a user starts typing in their city/location into an iOS app text field? For example, if you look at the yelp or maps app, when you start typing in a city it will provide suggestions based on what you start typing. Is there a way to do this, like somehow get a list of all the CLRegions in the CoreLocation framework, or some other way of implementing this?
Thanks for any help.
The best solution for this is to use someone else's (web-based) geocoding database - geocoding is a complex problem that you don't want to solve yourself :-). Geocoding is the act of taking a textual address and turning it into a latitude/longitude. Typeahead for geocoding is a helpful feature that requires fairly large databases that likely aren't suitable for mobile apps, thus my recommendation to use one of the web-based geocoding services for this.
Google's places API is probably a good candidate:

Check out this answer for some commentary from Google from 2011 when they first opened up that API in 2011:
Google Places API in iOS application
This might be a very stupid question for some people but I want to be make sure about this.
In iOS6 Apple has updated its Map application and added his own map. Now if I develop any native application and include map(MKMapView) into this so are their any changes which I should be aware of them?
Previously, I was using Google web service to fetch the latitude and longitude between two locations and draw direction. Does Apple provide its own web services for the same?
are their any changes which I should be aware of them?
MKMapView will still work fine, but the map it displays will look a little different. Also, if you limit your app to iOS versions that use only Apple's maps, you might not be subject to Google's terms and conditions. Read your agreements.
Does Apple provide its own web services for the same?
There's CLGeocoder. It's a class, not a web service, but that just makes it easier to use.
Using MKMapView framework didn't change just because the images are different. It should work fine.
Google's Terms Of Service say that you can't show their data on someone else's maps. So if your app is still getting data from a Google webservice you'll need to use the Google Map SDK that they have put out, not the usual MKMapView on iOS 6+.
If you are only using Google's webservice to turn a human readable address into lat/long then you can do that using CLGeocoder as Caleb suggested, but Google offer other services too.
I am using Google Places API to pull a list of resturants, and I am displaying them on map. However, since Apple has switched there map services over from Google in iOS 6.0, I am now in violation of Google's terms of use, which states that you must display Google data on a Google map.
"If your application displays Places API data on a map, that map must be provided by Google."
https://developers.google.com/places/policies#terms_of_use
I obviously need to change the map, because I am not going to release an application that is in violation. Any thoughts or suggestions on what to do? Should I go Google Maps with a web view? Does apple have some sort of Google Places API alternative?
Edit:
Using Google Maps through a web view is a hassle, i'd like to find an alternative to that, although it would technically work.
I decided to use Google Maps JavaScript API. Although, it is a little more difficult to deal with, mainly the JavaScript through Objective-C, it is a solution. The map is displayed through a web view, and I use JavaScript to interact with the map.

I will wait to accept this answer, to see if anyone else has any thoughts. I just wanted to post this, in case it helps someone else.
Edit:
Google recently released a Maps SDK for iOS, this is the better solution now.
https://developers.google.com/maps/documentation/ios/
I would try to directly contact Google, explaining the situation, and ask them for written permission to use Apple's maps. This is more a legal question than programming. One would think that Google is aware that you can no longer display their maps using Apple's API and that, even regardless of the map, they would want you to use their places, as doing so generates advertising revenue for them.
Agree with #Owen here - you could get permission to leave your app unchanged until some possible future date when you might have to change it, or could you definitely go to the effort of changing it now and then possibly have to change it again in the future for some other reason.
If you could get a 100% guarantee that you could change it once and never have to change it again then I'd say do it now, but nothing's certain.
Has anyone got any suggestions on where to start with building a google map into a rails app? I would like users to be able to add a marker by clicking the map, and have spent a few days looking for a suitable tutorial or plugin (beyond ym4r), to little avail...any help would be much appreciated as I am finding the Google Maps API rather difficult to get into! I've also come across the railskit for google maps - does anyone have any experience in using it?
Just fyi, I made https://rubygems.org/gems/gmaps4rails which is a useful wrapper with several options.
I probably wouldn't use YM4R. We tried it and found that it doesn't add much value because it just wraps the API. I would recommend working with Google Maps directly from JavaScript. Google Maps API documentation is pretty good, and there are quite a few examples on the web.
There is an example of a click handler on the map here, and adding a marker is just a matter of doing
map.addOverlay(new GMarker(latlng));
Does Google have a service that can make me able to access older satellite images using gmaps api for iOS?
Unfortunately, no. Looked around the community for a while and found a similar post that is pretty much asking for what you are aiming for. The selected answer has a link, which is also not a clear answer. I also tried the sample link (http://code.google.com/apis/ajax/playground/?exp=earth#time_and_historical_imagery_ui) provided in the comments but it doesn't seem to be working anymore.
I also managed to find this open feature request on Historical Satellite imagery . You can support it if you want.
