I want to learn how to use the forecast.io api in objective-C.

what's the equivalent of private let in objective-C Swift has Access Controls. I was wondering if i can do the same for Obj-C and make a similar app

In addition I want to use CoreLocation to find current location to find current weather and updates every times a user taps refresh

An iOS X-Code Project template for Forecast.io which is written in Obj-C which should provide a good starting point is here, https://github.com/brandonemrich/ForecastKit. I believe it will need the AFNetworking library via CocoaPods also. There are plenty of CoreLocation tutorials on the net but in iOS 8 you will need to add usage descriptions in the app's plist and a 'usage request' before implementing it's delegate or any other of it's methods.

For example

locationManager.requestWhenInUseAuthorization()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
locationManager.startUpdatingLocation()

For declaring constants in Obj-C would be something like this:

static NSString *const kConstant = @"myconstant";
