UIButton,UIImageView,UITextField

1.UIButton的基本设置

   //创建UIButton
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.frame = CGRectMake(150, 200, 70, 40);
    button.backgroundColor = [UIColor redColor];
    /**
     *  设置按钮标题
     *  标题内容
     *  按钮状态
     */
   
    [button setTitle:@"登录" forState:UIControlStateNormal];
    //设置标题颜色
    [button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
    //处于点击时发生高亮效果
    [button setShowsTouchWhenHighlighted:YES];
    //(常用)设置指定状态下的图片
    [button setBackgroundImage:[UIImage imageNamed:@"1.png"] forState:UIControlStateNormal];
   
    //设置指定状态下前景图
    [button setImage:[UIImage imageNamed:@"1"] forState:UIControlStateNormal];
    //添加tag值
    
    /*
     背景图片:照片的大小随着UIButton的frame大小改变
     前景图片:照片的大小就是照片的实际大小
     */
    //第一种
    //1.执行方法的对象 2.要执行的方法 3.需要触发的条件
   [button addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchUpInside];
    
    //第二种
    //[button addTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchDown];
    //第三种,移除按钮点击事件
    //[button removeTarget:self action:@selector(buttonAction) forControlEvents:UIControlEventTouchDown];
    [self.window addSubview:button];

//点击UIButton触发的事件
-(void)buttonAction
 {
     //通过tag值可以关联相应的视图
     UIButton *bu1 = (UIButton *)[self.window viewWithTag:1000];
     bu1.backgroundColor = [UIColor redColor];
     UITextField *tex = (UITextField *)[self.window viewWithTag:1001];
     [tex resignFirstResponder];
     UITextField *tex1 = (UITextField *)[self.window viewWithTag:1002];
     [tex1 resignFirstResponder];
    
     NSLog(@"气温要回升了");
 }

UITextField *textField1 = [[UITextField alloc] initWithFrame:CGRectMake(200, 50, 200, 40)];
    textField1.placeholder = @"请输入用户名";
    textField1.borderStyle = UITextBorderStyleRoundedRect;
    textField1.keyboardType = UIKeyboardTypeASCIICapable;
    //成为代理
    textField1.delegate = self;
    textField1.tag = 1001;
    [self.window addSubview:textField1];
//AppDelegate.h签署代理协议
@interface AppDelegate : UIResponder <UIApplicationDelegate,UITextFieldDelegate>

//Appdelegate.m实现代理方法
//代理方法
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    //释放第一响应者
    [textField resignFirstResponder];
    return YES;
}

 // 点击键盘return之后,回收键盘
    /**
     *  1.appdelete.h签订协议
     2.指定代理人(Appdelete)
     3.实现协议的方法
     */
    /*
     UITextField不应该在类的内部实现
      textFieldShouldReturn,因为有的时候,点击return时,并不是想收回键盘
     
     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
     */

2.UIImageView的基本设置

 NSMutableArray *array1 = [NSMutableArray array];
    for (int i = 1; i < 19; i++) {
        NSString *name = [NSString stringWithFormat:@"flower%d.tiff",i];
        UIImage *iamge = [UIImage imageNamed:name];
        [array1 addObject:iamge];
    }
    UIImageView *imageView4 = [[UIImageView alloc] initWithFrame:CGRectMake(50, 420, 100, 100)];
    //设置一组动态图片
    imageView4.animationImages = array1;
    //播放一组动态图片的时间
    imageView4.animationDuration = 1;
    //设置重复次数
    imageView4.animationRepeatCount = 0;
    //开始动画
    [imageView4 startAnimating];
    
    imageView4.tag = 1000;
    //添加到视图
    [self.imageView addSubview:imageView4];

UIImageView *imageView1 = [[UIImageView alloc] initWithFrame:CGRectMake(350, 50, 100, 150)];
    imageView1.animationImages = array4;
    imageView1.animationDuration = 1;
    imageView1.animationRepeatCount =0;
    [imageView1 startAnimating];
    [self.imageView addSubview:imageView1];
    
    //动画改变一个或者多个视图使用指定的持续时间
    [UIView animateWithDuration:20 animations:^{
        imageView1.frame = CGRectMake(-150, 500, 150, 150);
    }];

 -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

#import "AppDelegate.h"
#import "ViewController.h"
@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor greenColor];
        [self.window makeKeyAndVisible];
    self.window.rootViewController = [[ViewController alloc] init];
    
#pragma makr--------UITextField--------
    
    
    //创建UITextField
    UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(100, 100, 200, 40)];
    //设置颜色
    textField.backgroundColor = [UIColor whiteColor];
    //
    textField.alpha = 1;
    //设置字体颜色
    textField.textColor = [UIColor redColor];
    //----------外观控制-----------
      //1.边框样式
    textField.borderStyle = UITextBorderStyleRoundedRect;
      //2.清楚按钮
    textField.clearButtonMode = UITextFieldViewModeAlways;
    //-----------输入控制-----------
      //1.默认占位字符----一旦用户输入,自行隐藏
    textField.placeholder = @"请出入用户名";
      //2.加密模式 - 黑点模式
    textField.secureTextEntry = YES;
      //3.改变键盘样式
    textField.keyboardType = UIKeyboardTypeNumberPad;
    [self.window addSubview:textField];
