I want to get all tweets of user time line in iOS 4 with time, username, user image and user location latitude and longitude and post tweets on particular user wall with user current location latitude and longitude. How can I perform this?
Please provide me detailed information/link/url by which i can get all fields (i.e. username, time etc.).
You are asking two different questions. First, you want to look at the Twitter developers api to retrieve the data in a json format. Then, you want to find out how to parse the json data in iOS and display it.
You can read up on the Twitter API here: Twitter Developers.
Also, any reason for using iOS 4? The majority of users are now on iOS 5 or 6.
