UIView

    //设置viewUIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 20, kWidth, 100)];//设置背景色view.backgroundColor = [UIColor lightGrayColor];//设置坐标跟大小view.frame = CGRectMake(0, 0, kWidth-20, 100);//设置大小(不管坐标是多少,位置永远固定不变,但该位置是它所特有的位置,并不是之前的位置)view.bounds = CGRectMake(0, 0, 200, 200);//超过边界隐藏,默认是不隐藏(隐藏谁即是谁的属性)view.clipsToBounds = YES;//获取frame  boundsCGRect frame = view.frame;CGRect bounds = view.bounds;NSLog(@"%@",NSStringFromCGRect(frame));NSLog(@"%@",NSStringFromCGRect(bounds));//设置tag值(只要继承UIView均可设置tag值)view.tag = 101;//设置圆角view.layer.cornerRadius = 10;//设置阴影颜色(不要忘掉.CGColor)view.layer.shadowColor = [UIColor blackColor].CGColor;//设置阴影的不透明度(0~1)view.layer.shadowOpacity = 1;//设置阴影的圆角view.layer.shadowRadius = 5;//设置阴影的大小(默认是(0,-3))view.layer.shadowOffset = CGSizeMake(5, 10);//设置边界view.layer.borderColor = [UIColor redColor].CGColor;//设置边界宽度view.layer.borderWidth = 2; //添加[self.view addSubview:view];

• pragma mark 点击空白处进行的事件

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{//获取所有子视图(返回值是一个数组)NSArray *subViewsArray = [self.view subviews];NSLog(@"%@",subViewsArray);//取出所有子视图的最上面一个UIView *lastView = [subViewsArray lastObject];NSLog(@"%@",NSStringFromCGRect(lastView.frame));//将最上面一个移动到最后(即数组的第0个,谁是父视图谁调用)
    [self.view sendSubviewToBack:lastView];NSArray *array = [self.view subviews];NSLog(@"%@",array);//根据tag值调取视图(父视图调用)UIView *tagView = [self.view viewWithTag:101];//将视图隐藏的三种方法//1.改变透明度tagView.alpha = 0.5;//2.从父视图移除
    [self.view removeFromSuperview];//3.隐藏tagView.hidden = !tagView.hidden;//计时器的开启[NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(change) userInfo:nil repeats:YES];}

UIButton

 　　//设置buttonUIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(20, 20, 100, 50)];//设置按钮的圆角button.layer.cornerRadius = 0;//居中button.center = self.view.center;//设置颜色button.backgroundColor = [UIColor whiteColor];//设置图标(只有添加了图标或背景图片,才会有点击效果,并且该方法是以图标形式添加的)[button setImage:[UIImage imageNamed:@"channel_friend_love"] forState:UIControlStateNormal];[button setImage:[UIImage imageNamed:@"hongxin"] forState:UIControlStateSelected];//设置图标(该方法添加的是铺满的背景图)[button setBackgroundImage:[UIImage imageNamed:@"bthui2"] forState:UIControlStateNormal];//设置标题[button setTitle:@"UIControlStateNormal" forState:UIControlStateNormal];[button setTitle:@"UIControlStateSelected" forState:UIControlStateSelected];[button setTitle:@"UIControlStateDisabled" forState:UIControlStateDisabled];//设置字体的大小button.titleLabel.font = [UIFont systemFontOfSize:12];//设置标题颜色
    [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];//标题水平对齐(对齐方式以此类推)
    [button setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];//移动图片(CGFloat top, left, bottom, right  在原有基础上增加或减少的相对于边缘的距离)[button setImageEdgeInsets:UIEdgeInsetsMake(10, 10, 0, 0)];//移动标题(CGFloat top, left, bottom, right  在原有基础上增加或减少的相对于边缘的距离)[button setTitleEdgeInsets:UIEdgeInsetsMake(10, -10, 0, 0)];//监视点击事件
//    [button addTarget:self action:@selector(click) forControlEvents:UIControlEventTouchUpInside];//添加[self.view addSubview:button];

• pragma mark 点击事件,控制器切换

-(void)click{//初始化控制器MyViewController *mVC = [MyViewController new];//控制器切换效果
  [mVC setModalTransitionStyle:UIModalTransitionStyleCoverVertical];[self presentViewController:mVC animated:YES completion:^{}];
}

 

• pragma mark 点击空白处,如果定时器对象为空,则重新启动定时器,如果定时器对象不为空,则让定时器对象失效(invalidate方法)

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{if (_timer == nil) {_timer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(change) userInfo:nil repeats:YES];}else{[_timer invalidate];_timer = nil;}
}

UISlider

　　//设置slider(高度不起作用)UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(0, 0, 200, 45)];//居中slider.center = self.view.center;//slider的默认范围是0~1,可通过value值来改变范围//设置最小值slider.minimumValue = 0;//设置最大值slider.maximumValue = 10;//设置当前值slider.value = 5;//设置圆点的颜色
    [slider setThumbTintColor:[UIColor redColor]];//设置圆点的图片[slider setThumbImage:[UIImage imageNamed:@"hongxin"] forState:UIControlStateNormal];//设置已跑轨道的颜色(同样也可设置图片)
    [slider setMinimumTrackTintColor:[UIColor blueColor]];//设置未跑轨道的颜色(同样也可设置图片)
    [slider setMaximumTrackTintColor:[UIColor redColor]];//添加
    [self.view addSubview:slider];//开始计时器,让进度条动起来[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(move) userInfo:nil repeats:YES];

• pragma mark 改变进度值

-(void)move{_slider.value = _slider.value++;}
