Generally every person who is net freak starts his day by going through his RSS feeds. People like me, subscribe to many RSS feeds about programming, iPhone & Apple tech, Usability and stuff. Everyday I have about 30 unread articles in my reader app (I use NetNewsWire on mac). People start going through these articles and they really end up reading only small percentage of those unread, Usually only 5-6 out of 30. As most of the Articles are about same thing, same news, same product explored or smashed. Thats where the problem begins. What people want to read at…

While working with NSDate and sqlite3 on iPhone the common problem many people face is about storing and retrieving NSDate from sqlite3 database. There are mainly two methods to do so, one is to get the time interval (timeIntervalSince1970) from reference date and save the interval as double value in the database, second is to convert date into string using NSDateFormatter and save the text value in the database. NOTE: The type of column where we want to store NSDate should be DATETIME in both the methods. Method 1: using timeIntervalSince1970 Writing NSDate to sqlite3 DB NSDate *dateToWrite = [NSDate…

Emoji is the Japanese term for the picture characters or emoticons used in Japanese wireless messages and webpages. Originally meaning pictograph, the word literally means e “picture” + moji “letter”. The characters are used much like emoticons elsewhere, but a wider range is provided, and the icons are standardized and built into the handsets. The three main Japanese operators, NTT DoCoMo, au and SoftBank Mobile (formerly Vodafone), have each defined their own variants of emoji. Ok enough of this….Lets see how to enable this keyboard to be used everywhere. (By default this keyboard is only works on iPhones from Japan)…

This is the example for how to create flipping bar button like iTunes. I faced the same problem while developing solutions for first time, after looking at iTunes app more closely..it seems the flipping thing in Navigation Bar is not a BarButton but button with images ( It does not show highlighted effect ). All we need to do is use custom UIBarButtonItem with CustomView for this. Step 1: Create UIBarButton with CustomView barButtonSuperView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 34, 30)]; barButtonPrimaryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 34, 30)]; UIButton * primaryButton = [UIButton buttonWithType:UIButtonTypeCustom]; primaryButton.frame = CGRectMake(0, 0, 34,…

I have seen many many applications so far, i mean really awesome applications. Still one thing i see which is almost common with all of them except few one is that Custom UITableViewCells does not change text color when selected/highlighted. I am also a developer and i know these kind of things miss out while developing applications in rapid development cycles and under timeline pressure :(. but then it really shows high level of ignorance from developers side. The solution is simple. Generally what we do is we create custom UIView and add it inside UITableViewCell. Just we need to…

The new Yahoo messenger v9.0 uses ymsg 16 protocol. For login process client sends username and password to yahoo login server: https://login.yahoo.com, and in response server sends Token which is then used for client authentication process on scs.msg.yahoo.com:5050 This login process goes through multiple steps as follows..

Firstly, I would like to talk about the first year; there is lot to say about. I was in some other college then I got admission here, in Watumull. Those days were so different than today’s. I was one unknown guy in that class. I still remember, our class was on the fourth floor first room – a ‘window-class’ with very beautiful view of the sea face. In all labs chintu, saili, pappu, neha n me were in one group. Always these girls used to do all calculations n we all guy used to copy those things. We were together…
