最近剛開始學(xué)IOS，用的Xcode5中默認(rèn)生成的Storyboard中控件的好多屬性設(shè)置不了，所以就嘗試在空項目里手寫button，如有錯誤，請指正，共同學(xué)習(xí)。

1.新建ViewController類，我起的名字是MCViewController。

2.創(chuàng)建mccontroller控制器，并設(shè)置window的根視圖為mccontroller。

AppDelegate.m

 1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 2 { 3     self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 4     // Override point for customization after application launch. 5     self.window.backgroundColor = [UIColor whiteColor]; 6     [self.window makeKeyAndVisible]; 7     //自定義code 8     MCViewController *mccontroller =[[MCViewController alloc] init]; 9     self.window.rootViewController=mccontroller;10     //code end11     return YES;12 }

3.創(chuàng)建按鈕

MCViewController.m

 1 - (void)viewDidLoad 2 { 3     [super viewDidLoad]; 4     // Do any additional setup after loading the view. 5      6     //btn_enter 定義 7     UIButton *btn_enter=[UIButton buttonWithType:UIButtonTypeRoundedRect]; 8     btn_enter.frame=CGRectMake(20, 360, 280, 40); 9     btn_enter.backgroundColor = [UIColor clearColor];10     [btn_enter.layer setMasksToBounds:YES];11     [btn_enter.layer setCornerRadius:10.0]; //設(shè)置矩形四個圓角半徑12     [btn_enter.layer setBorderWidth:1.0]; //邊框?qū)挾?/span>13     [btn_enter setTitle:@"點擊" forState:UIControlStateNormal];14     [btn_enter addTarget:self action:@selector(click_btn_enter:) forControlEvents:UIControlEventTouchUpInside];15     [self.view addSubview:btn_enter];16     17     //btn_quit 定義18     UIButton *btn_quit=[UIButton buttonWithType:UIButtonTypeRoundedRect];19     btn_quit.frame=CGRectMake(20, 420, 280, 40);20     btn_quit.backgroundColor=[UIColor clearColor];21     [btn_quit.layer setMasksToBounds:YES];22     [btn_quit.layer setCornerRadius:10];23     [btn_quit.layer setBorderWidth:1.0];24     [btn_quit setTitle:@"退出" forState:UIControlStateNormal];25     [btn_quit addTarget:self action:@selector(click_btn_quit:) forControlEvents:(UIControlEventTouchUpInside)];26     [self.view addSubview:btn_quit];27 }

4.聲明按鈕動作

MCViewController.h

1 @interface MCViewController : UIViewController2 -(IBAction)click_btn_enter:(UIButton *)sender;3 -(IBAction)click_btn_quit:(UIButton *)sender;4 @end

5.實現(xiàn)按鈕動作

MCViewController.m

1 -(IBAction)click_btn_enter:(UIButton *)sender{2     NSLog(@"I am enter!!!");3 }4 5 -(IBAction)click_btn_quit:(UIButton *)sender{6     NSLog(@"I am quit!!!");7 }
