We all sometimes do something with photos in our apps. And apps that deal with photos in some way, whether it be editing, stylishing or sharing them, are becoming more and more popular every day.

Google Analytics is a full-featured, enterprise-class web analytics service from Google for tracking web and mobile application usage statistics. It’s a good idea to track how your customers use your app. There are many benefits of knowing how your app is actually being used. You can optimize some parts of your application, make decisions on adding, dropping or improving a feature or make modifications in UI to improve the usability of your app. You don’t want to work on a feature that nobody actually uses, right?

Imagine you have the following problem: You want to load a url in a UIWebView. But the resource at that url requires authentication, and if the user is not authenticated the web page responds with a “403 Not Authenticated” without showing any other instructions on how to login or where to go next etc. Ideally you’d want to redirect the user to a page where she can log in and continue to browse the url. The problem is UIWebView does not provide any properties or methods for inspecting HTTP status codes. One workaround is to intercept the UIWebView request loading process and check whether the user is authenticated or not by loading the same url using an NSURLConnection and inspecting the response, then you can behave accordingly.

As all of us knows, location-aware services/applications are becoming more popular and widespread everyday. Especially, mobile devices play a very important role in that area. So we all, in some ways, need to access the location of a specific user of our app. Most of the mobile devices provides some hardware and APIs for letting application developers to access location services of the device. iPhone has a built-in GPS module and a framework is provided in Cocoa Touch called CoreLocation that is used for accessing location services of the device.
CoreLocation can be used to obtain the latitude and longitude parameters of the location of the device. But sometimes we need some more detailed information about that specific location. Country, city, state, street, may be postal code etc.. It depends on the application. That is something iPhone or iOS platform does not provide directly. However, we can use a web service such as Yahoo! PlaceFinder to access detailed information about a location of which we know the latitude and longitude parameters.
What SSLocationManager does is as follows:
- Ask CoreLocation services to determine current location of the device.
- Get current position in latitude and longitude from CoreLocation.
- Call Yahoo! PlaceFinder web service to get detailed information about the location specified with its latitude and longitude.
- Notify the application via SSLocationManagerDelegate and supply the detailed location data.
Here is a basic diagram that shows the overall structure:
