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 end11 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 : UIViewController2 -(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 }
