the button in XibTo add a click event to a button in xib, you need to use the action ibaction. Ibaction is a method that connects to an event on a control in Xib. This method is called when the user triggers this event for the control.Open the auxiliary editor for Xcode as in the previous step, The secondary editing interface displays the TRVIEWCONTROLLER.M file, selects the button object in the Xib, and control-drags the button to the trviewcontroller.m file, releasing the Mouse, which pops up

Date RangeYou can specify the date range to use by setting the Mininumdate and Maxinumdate properties. If a user attempts to scroll to a date beyond this range, the dial rolls back to the most recent valid date. Two methods require the NSDate object as a parameter:Copy CodeThe code is as follows:nsdate* mindate = [[NSDate alloc]initwithstring:@ "1900-01-01 00:00:00-0500"];nsdate* maxdate = [[NSDate alloc]initwithstring:@ "2099-01-01 00:00:00-0500"];Datepicker.minimumdate = MinDate;Datepicker.ma

IOS development-custom list controls In the past two days, projects are relatively idle. When you are idle, You can implement the list control by yourself. It took about one day from the start of the project to the preliminary completion. At present, simple functions of the list are implemented. In the future, we will consider adding cell reuse mechanisms, inertial features, deletion of cell and other funct
