As a father of two young children, I am always on the lookout for useful apps to track my kids’ health. There is a new useful application that will be released soon called Baby Growth Chart Tracker App that will track your children’s weight, height, head circumference and BMI using the World Health Organization (WHO) […]
UITextField’s Limitation UITextField has a property called secureTextEntry that hides the characters as you type them (except for the last one, which is hidden after a brief moment). This is useful for things like a password field. However, you will notice that the keyboard icon that lets you choose languages is absent. This means that […]
Java has a very useful class called the BlockingQueue. With a blocking queue, the dequeue operation will block until there is something to be dequeued. A blocking queue is very handy and can be used to solve the classic producer-consumer problem. I needed a similar class in Objective-C, but I could not find one. The […]
