IOSApplication新建Empty项目中自定义UIButton

最近刚开始学IOS，用的Xcode5中默认生成的Storyboard中控件的好多属性设置不了，所以就尝试在空项目里手写button，如有错误，请指正，共同学习。

 

 

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

 

2.创建mccontroller控制器，并设置window的根视图为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     //自定义code

 8     MCViewController *mccontroller =[[MCViewController alloc] init];

 9     self.window.rootViewController=mccontroller;

10     //code end

11     return YES;

12 }

 

3.创建按钮

 

MCViewController.m

 1 - (void)viewDidLoad

 2 {

 3     [super viewDidLoad];

 4     // Do any additional setup after loading the view.

 5     

 6     //btn_enter 定义

 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]; //设置矩形四个圆角半径

12     [btn_enter.layer setBorderWidth:1.0]; //边框宽度

13     [btn_enter setTitle:@"点击" forState:UIControlStateNormal];

14     [btn_enter addTarget:self action:@selector(click_btn_enter:) forControlEvents:UIControlEventTouchUpInside];

15     [self.view addSubview:btn_enter];

16     

17     //btn_quit 定义

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.声明按钮动作

 

MCViewController.h

1 @interface MCViewController : UIViewController

2 -(IBAction)click_btn_enter:(UIButton *)sender;

3 -(IBAction)click_btn_quit:(UIButton *)sender;

4 @end

 

5.实现按钮动作

 

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 }
