Simple login layout for ios Learning

Haha, I am a local tyrant. I have to buy a mac and start to install it. I can't be idle when I buy it. By the way, I want to learn about ios and learn a simple login interface, all apps have logon interfaces. Start!

Let's take a look:

 

 

 

Click the code above:

{UITextField * phone; UITextField * code; UIButton * btn; UIButton * getcode;} @ end @ implementation MineUiViewController-(void) viewDidLoad {[super viewDidLoad]; UILabel * title = [[UILabel alloc] initWithFrame: CGRectZero]; title. backgroundColor = [UIColor clearColor]; title. textColor = [UIColor whiteColor]; self. navigationItem. titleView = title; title. text = @; [title sizeToFit]; self. navigationController. navigationBar. barTintColor = [UIColor redColor]; [self. navigationController. navigationBar setTranslucent: NO]; int width = (self. view. frame. size. width); int leftandright = 6; int top = 6; phone = [[UITextField alloc] initWithFrame: CGRectMake (top, top, width * 2/3, 50)]; phone. textColor = [UIColor greenColor]; phone. font = [UIFont systemFontOfSize: 15]; phone. placeholder = @ enter the mobile phone number. phone. backgroundColor = [UIColor grayColor]; phone. returnKeyType = UIReturnKeyDefault; phone. keyboardType = UIKeyboardTypeDefault; phone. delegate = self; phone. keyboardType = UIKeyboardTypeNumberPad; [self. view addSubview: phone]; getcode = [[UIButton alloc] initWithFrame: CGRectMake (width * 2/3 + top * 2, top, width * 1/3-top * 3, 50)]; getcode. backgroundColor = [UIColor blackColor]; [getcode setTitle: @ fuck forState: UIControlStateNormal]; [getcode addTarget: self action: @ selector (getcode) forControlEvents :( UIControlEventTouchUpInside)]; [self. view addSubview: getcode]; int y = 50; y + = 20; code = [[UITextField alloc] initWithFrame: CGRectMake (top, y, width-top * 2, 50)]; code. textColor = [UIColor blueColor]; code. font = [UIFont systemFontOfSize: 15]; code. placeholder = @ enter the verification code. backgroundColor = [UIColor grayColor]; code. returnKeyType = UIReturnKeyDefault; code. keyboardType = UIKeyboardTypeDefault; code. delegate = self; code. keyboardType = UIKeyboardTypeNumberPad; [self. view addSubview: code]; y + = 50; y + = 20; btn = [[UIButton alloc] initWithFrame: CGRectMake (top, y, width-top * 2, 50)]; btn. backgroundColor = [UIColor redColor]; [btn setTitle: @ fuck forState: UIControlStateNormal]; [btn addTarget: self action: @ selector (getcode) forControlEvents: UIControlEventTouchUpInside]; [self. view addSubview: btn];}-(void) getcode {UIAlertView * show = [[UIAlertView alloc] initWithTitle: @ are you kidding me? message: @ you guess delegate: nil cancelButtonTitle: @ is otherButtonTitles: @ Yes, nil]; [show];}-(void) didReceiveMemoryWarning {[super didreceivemorywarning]; // Dispose of any resources that can be recreated .} @ en
 

 

If you want to enter this interface, you have to modify it in appdelegate:

 

//// AppDelegate. m // UITabview /// Created by xiaoyuan on 15/4/16. // Copyright (c) 2015 xiaoyuan. all rights reserved. // # import AppDelegate. h # import MineUiViewController. h @ interface AppDelegate () @ end @ implementation AppDelegate-(BOOL) application :( UIApplication *) application didfinishlaunchingwitexceptions :( NSDictionary *) launchOptions {// Override point for customization after application launch. // create _ window = [[UIWindow alloc] initWithFrame: CGRectMake (0, 0,400,600)]; _ window. backgroundColor = [UIColor whiteColor]; MineUiViewController * rootVC = [[MineUiViewController alloc] init]; UINavigationController * nav = [[UINavigationController alloc] handler: rootVC]; _ window. rootViewController = nav; [_ window makeKeyAndVisible]; return YES;}-(void) applicationWillResignActive :( UIApplication *) application {// Sent when the application is about to move from active to inactive state. this can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. games shocould use this method to pause the game .} -(void) applicationDidEnterBackground :( UIApplication *) application {// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits .} -(void) applicationWillEnterForeground :( UIApplication *) application {// Called as part of the transition from the background to the inactive state; here you can undo records of the changes made on entering the background .} -(void) applicationDidBecomeActive :( UIApplication *) application {// Restart any tasks that were paused (or not yet started) while the application was inactive. if the application was previusly in the background, optionally refresh the user interface .} -(void) applicationWillTerminate :( UIApplication *) application {// Called when the application is about to terminate. save data if appropriate. see also applicationDidEnterBackground :.} @ end
