ios - Change text in label to "hi" after you click the button -



ios - Change text in label to "hi" after you click the button -

what wrong meant alter text in label "hi" after click button.

viewcontroller.swift:

// // viewcontroller.swift // helloswift // // created abdel rahman osman on 10/13/14. // copyright (c) 2014 abdel rahman osman. rights reserved. // import uikit class viewcontroller: uiviewcontroller { @iboutlet weak var textgoeshere: uilabel! @ibaction func printtext(sender: anyobject) { var text = textgoeshere.text text = "hi" } override func viewdidload() { super.viewdidload() // additional setup after loading view, typically nib. } override func didreceivememorywarning() { super.didreceivememorywarning() // dispose of resources can recreated. } }

please help me prepare code new app development.

what doing creating re-create of text in label, discard , reassign new value, , discard 1 time again when variable goes out of scope.

the right way assigning text straight text property:

@ibaction func printtext(sender: anyobject) { textgoeshere.text = "hi" }

ios swift uiviewcontroller

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
