There are lots of similar questions but my question is different in that sense i got coordinates of my current location in my application.
But now i want to show specific business offices in table view around that coordinates. I know ReverseGeoConding is answer to that but i cant find suitable tutorial or advice on this. How can i implement it.
Please suggest .
Reverse Geocoding will provide you with address information for the coordinates provided. In order to get businesses around those coordinates, you may want to look into external APIs. I believe Facebook has a Places API and Foursquare has an API as well. These may be able to provide you with local business information.

I want to know if there is any way to get a city/suburb/postal code's outer boundary coordinates, so as to be able to draw a polygon on the map.
I have read through the google maps API documentation (Places, Maps, and Routes) and I can't find anywhere where they provide this information.
Native in google maps if you search for a city google maps will draw a polygon around the city edges. Drawing the polygon is not the issue I just want to know how to get the polygon points for any given location.
I have searched and all the available answers are either very old or provided only a community maintained polygon database, that is not guaranteed to have your location mapped.
So my question is, do google maps APIs expose some function to get these coordinates, or is there some reputable well maintained service where this information can be obtained from?
I am using it in a flutter applicant making use of google_maps_flutter.
These are some of the resources and other links I found but seem dated.

Googles Docs
Please please help.
I'm not sure that the Google Maps API offers this functionality, but I trust that you've dug through enough of their documentation to find that they don't.
I suggest looking at Nominatim, which queries data from OSM (OpenStreetMap). They're free to use and community-driven - which can be both awesome and scary (eg. you can't assume "permanent ID"s for the things you query)
Relevant Links:
https://nominatim.org/release-docs/latest/api/Overview/
https://nominatim.openstreetmap.org/ui/search.html
Otherwise, you could also try looking for other tools that allow you to download datasets of boundary coordinates (eg: GADM) but you'd have to find one that has the level of granularity you need and read up on their usage policies (most disallow use for commercial purposes).
Unfortunately the world of GIS and digital cartography is one that can get pretty complicated and that I'm no expert in, but I hope this helps somewhat.
Listing other resources I've found that are rather outdated, but could still be helpful:

We are developing an application that utilizes several of the supported place types in the Google Places API. But, we have noticed that the supported type, restaurant code, is different from the restaurant info you would find at the bottom page of a Google page on a smart phone. Example; the restaurant info given from a smart phone provides restaurant details and location. The one listed in Google Places API does not show the same info. Please inform us how we can obtain the codes for the same info that’s provided on the Google page from a smart phone. Is it free or part of a premium deal with Google? Thanks, and I hope this is clear.

The Google Places database is different from Google Maps.
I'd imagine that at some point, Google would unite the two.
You could match by lat/long & name. This would probably work for at least half the time. The other half means the name & lat/long from both databased maybe a little different.
I am new iphone developer,please help to me.how can i find particular shops list in particular Zip Code.. that means i need to place pins in Some shops by searching Zipcode
Thanks in advance
I'm not sure there's a definitive "Right Way" to do what you're asking, but if it were me...
I would probably use Google's Places API to get a list of so-called Places (I gather this includes a fairly comprehensive list of businesses, as well as other points of interest) near the user. The API requires lat/long coordinates to resolve the list, you could either get that data from the user's iOS device (I don't develop for this platform so I can't give specifics) using Apple's location API, or if you really want to do a lookup by zipcode you might want to look at Google's Geocoding API. Keep in mind that Google's services are by no means the only game in town, and there are certainly other ways to do what you ask. But if it was me, this seems like the simplest solution
I am new to GPS.If i send "hotels" in label , any free webservice is available to see them as map?any tutorial please? is there any free webservice to give location name if i give current latitude & longitude values?
Taking your questions one by one :
is there any free webservice to give location name if i give current latitude & longitude values?
This is called reverse geocoding and it's in the SDK already - check out the docs here.
any free webservice available to see them as a map
A quick google search for 'hotels api' found a few results for hotels data feeds like this one.
You will also need to read the documentation for MKMapView - there are a few sample apps linked from that page that it's worth downloading and seeing how they work.
any tutorial please
Google for it - a quick search for 'map kit tutorial' returns this as the first link.
PS One of the best ways to get your question ignored is to ask more than one thing at once - you've asked three questions here and seem to have made no effort to find out the answers yourself first - people generally don't like that (take a look at the comments if you don't believe me!)
If you have more than one question, ask them separately here on stack overflow and give some examples of things that you have tried already :)
I have read about a number of posts for developers who want to plot out a route on a map on an iPhone but there is no satisfactory answer as how to best achieve this. You can use the Route-Me library, add a layer on top MKMapView or send coordinates to phones map software then you navigate from your application, which in my opinion is bad user experience.
None of this solves the problem in a good way.
Some Post writes that there are legal obstacles, others write that it is about licensing money. This must be a very common requirement and thus a common feature to implement. So what is the de-facto standard way to do this?
Can someone with good experience share their insights on this question?

So I decided to use Apple Developer Technical Support to really clear this out. This is the reply:
Hello,
Thank you for your inquiry to Apple Worldwide Developer Technical Support.
I am responding to let you know that I have received your request for technical assistance.
The de-facto standard way of doing this is using the Map application. I realize this is not what you want. You want to stay within your app. The MKMapView API does not give you that level of support when it comes to user directions. You will have to rely on a separate web service to obtain those directions, then plot each lat/long point yourself on the MKMapView. Basically you will need to make an HTTP request to the Google Directions API. The terms require you to display the results on a Google map; since MKMapView shows Google, that should be OK.
http://code.google.com/apis/maps/documentation/directions/#DirectionsRequests
If you succeed in obtaining driving directions from let say Yahoo or Google service, MKMapView will allow you to plot a visual course using an MKOverlayPathView and MKShapes to draw polygon-like shapes. Apple has a sample called "KMLViewer" found at
http://developer.apple.com/library/ios/#samplecode/KMLViewer/Introduction/Intro.html
It shows you how to plot points based on KML. The approach is the same since we are dealing with lat/long coordinates.
You may want to consider using the Map application, which would be considerably easier. All you need is this:
// for lat/long directions
NSString *urlString1 = #"http://maps.google.com/maps?daddr=37.324885,-122.032378&saddr=37.332094,-122.03124";
// for address directions
NSString *urlString2 = #"http://maps.google.com/maps?f=d&source=s_d&saddr=1+Infinite+Loop,+Cupertino,+CA+95014&daddr=Mandarin+Gourmet,+Cupertino,+CA&hl=en&geocode=FcajOQIdYvO5-Ckbd16TtrWPgDFAc4Pi50E92A%3BFZ2GOQIdLe65-CHRv0sTH7YegykLqKn9rbWPgDGUnqKbIqi1Bg&mra=ls&sll=37.325567,-122.032989&sspn=0.007243,0.007285&ie=UTF8&ll=37.328195,-122.031466&spn=0.007243,0.007285&z=17";
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: urlString1]];
SECOND E-MAIL:
Just to be clear in my last e-mail about the terms for using Google services. Google requires you to display the route results on a Google map, which MKMapView uses. However, I would double-check Apple's own T&Cs regarding the use of external services like user directions on MKMapView itself. I don't want you do go down a path only to find legal restrictions along the way.
