1.UIButton的基本设置
1 //创建UIButton 2 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 3 button.frame = CGRectMake(150, 200, 70, 40); 4 button.backgroundColor = [UIColor redColor]; 5 /** 6 * 设置按钮标题 7 * 标题内容 8 * 按钮状态 9 */ 10 11 [button setTitle:@"登录" forState:UIControlStateNormal]; 12 //设置标题颜色 13 [button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal]; 14 //处于点击时发生高亮效果 15 [button setShowsTouchWhenHighlighted:YES]; 16 //(常用)设置指定状态下的图片 17 [button setBackgroundImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal]; 18 19 //设置指定状态下前景图 20 [button setImage:[UIImage imageNamed:@"1"] forState:UIControlStateNormal]; 21 //添加tag值 22 23 /* 24 背景图片:照片的大小随着UIButton的frame大小改变 25 前景图片:照片的大小就是照片的实际大小 26 */ 27 //第一种 28 //1.执行方法的对象 2.要执行的方法 3.需要触发的条件 29 [button addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchUpInside]; 30 31 //第二种 32 //[button addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchDown]; 33 //第三种,移除按钮点击事件 34 //[button removeTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchDown]; 35 [self.window addSubview:button]; 36 37 //点击UIButton触发的事件 38 -(void)buttonAction 39 { 40 //通过tag值可以关联相应的视图 41 UIButton *bu1 = (UIButton *)[self.window viewWithTag:1000]; 42 bu1.backgroundColor = [UIColor redColor]; 43 UITextField *tex = (UITextField *)[self.window viewWithTag:1001]; 44 [tex resignFirstResponder]; 45 UITextField *tex1 = (UITextField *)[self.window viewWithTag:1002]; 46 [tex1 resignFirstResponder]; 47 48 NSLog(@"气温要回升了"); 49 }
1 UITextField *textField1 = [[UITextField alloc] initWithFrame:CGRectMake(200, 50, 200, 40)]; 2 textField1.placeholder = @"请输入用户名"; 3 textField1.borderStyle = UITextBorderStyleRoundedRect; 4 textField1.keyboardType = UIKeyboardTypeASCIICapable; 5 //成为代理 6 textField1.delegate = self; 7 textField1.tag = 1001; 8 [self.window addSubview:textField1]; 9 //AppDelegate.h签署代理协议 10 @interface AppDelegate : UIResponder <UIApplicationDelegate,UITextFieldDelegate> 11 12 //Appdelegate.m实现代理方法 13 //代理方法 14 -(BOOL)textFieldShouldReturn:(UITextField *)textField 15 { 16 //释放第一响应者 17 [textField resignFirstResponder]; 18 return YES; 19 } 20 21 // 点击键盘return之后,回收键盘 22 /** 23 * 1.appdelete.h签订协议 24 2.指定代理人(Appdelete) 25 3.实现协议的方法 26 */ 27 /* 28 UITextField不应该在类的内部实现 29 textFieldShouldReturn,因为有的时候,点击return时,并不是想收回键盘 30 31 对于一个V来说,自己只负责触发事件,事件由外部实现,即delegate 32 */
2.UIImageView的基本设置
1 NSMutableArray *array1 = [NSMutableArray array]; 2 for (int i = 1; i < 19; i++) { 3 NSString *name = [NSString stringWithFormat:@"flower%d.tiff",i]; 4 UIImage *iamge = [UIImage imageNamed:name]; 5 [array1 addObject:iamge]; 6 } 7 UIImageView *imageView4 = [[UIImageView alloc] initWithFrame:CGRectMake(50, 420, 100, 100)]; 8 //设置一组动态图片 9 imageView4.animationImages = array1; 10 //播放一组动态图片的时间 11 imageView4.animationDuration = 1; 12 //设置重复次数 13 imageView4.animationRepeatCount = 0; 14 //开始动画 15 [imageView4 startAnimating]; 16 17 imageView4.tag = 1000; 18 //添加到视图 19 [self.imageView addSubview:imageView4];
1 UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(350, 50, 100, 150)]; 2 imageView1.animationImages = array4; 3 imageView1.animationDuration = 1; 4 imageView1.animationRepeatCount =0; 5 [imageView1 startAnimating]; 6 [self.imageView addSubview:imageView1]; 7 8 //动画改变一个或者多个视图使用指定的持续时间 9 [UIView animateWithDuration:20 animations:^{ 10 imageView1.frame = CGRectMake(-150, 500, 150, 150); 11 }];
-150表示的是imageView1最后的X的坐标是从window的原点向左偏移150,由于它自身的长为150,要想最后图片全部消失在视图上则需要X的坐标与它的长度和小于零才可以
3.UITextField的基本设置
1 #import "AppDelegate.h" 2 #import "ViewController.h" 3 @interface AppDelegate () 4 5 @end 6 7 @implementation AppDelegate 8 9 10 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 11 12 self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; 13 self.window.backgroundColor = [UIColor greenColor]; 14 [self.window makeKeyAndVisible]; 15 self.window.rootViewController = [[ViewController alloc] init]; 16 17 #pragma makr--------UITextField-------- 18 19 20 //创建UITextField 21 UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(100, 100, 200, 40)]; 22 //设置颜色 23 textField.backgroundColor = [UIColor whiteColor]; 24 // 25 textField.alpha = 1; 26 //设置字体颜色 27 textField.textColor = [UIColor redColor]; 28 //----------外观控制----------- 29 //1.边框样式 30 textField.borderStyle = UITextBorderStyleRoundedRect; 31 //2.清楚按钮 32 textField.clearButtonMode = UITextFieldViewModeAlways; 33 //-----------输入控制----------- 34 //1.默认占位字符----一旦用户输入,自行隐藏 35 textField.placeholder = @"请出入用户名"; 36 //2.加密模式 - 黑点模式 37 textField.secureTextEntry = YES; 38 //3.改变键盘样式 39 textField.keyboardType = UIKeyboardTypeNumberPad; 40 [self.window addSubview:textField];
