进击的UI------------------UISegmentedControl&UISlide

1.UISegmentedControl

①:初始

self.segment = [[UISegmentedControl alloc]initWithItems:

[NSArray arrayWithObjects:@"一卡通",@"信用卡",@"一网通", nil]];

self.segment.frame = CGRectMake(0, 20, self.frame.size.width, 50);

 [self addSubview:_segment];

②:设置标题

[self.rv.segment setTitle:@"第二项" forSegmentAtIndex:0];

③:默认被选中的选项

self.rv.segment.selectedSegmentIndex  = 1;

④:边框和字体的颜色

 self.rv.segment.tintColor = [UIColor orangeColor];

⑤:设置图片

 self.rv.segment setImage:(UIImage *) forSegmentAtIndex:<#(NSUInteger)#>

⑥:获取图片

self.rv.segment imageForSegmentAtIndex:

⑦:获取title

self.rv.segment titleForSegmentAtIndex:<#(NSUInteger)#>

⑧:插入一个

[self.rv.segment insertSegmentWithTitle:@"3" atIndex:3 animated:YES];

⑨:删除一个

[self.rv.segment removeSegmentAtIndex:3 animated:YES];

⑩:事件

[self.rv.segment addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];

- (void)segmentAction:(UISegmentedControl *)sender{

    if (sender.selectedSegmentIndex == 0) {

        UIView *view1 = [[UIView alloc]initWithFrame:CGRectMake(0, 70, self.rv.frame.size.width, self.rv.frame.size.height - 70)];

       

        view1.backgroundColor = [UIColor colorWithRed:arc4random()%2/1.0 green:arc4random()%2/1.0 blue:arc4random()%2/1.0 alpha:1];

        [self.rv addSubview:view1];

    }else if (sender.selectedSegmentIndex == 1){

        UIView *view2 = [[UIView alloc]initWithFrame:CGRectMake(0, 70, 375, 600)];

       

        view2.backgroundColor = [UIColor colorWithRed:arc4random()%2/1.0 green:arc4random()%2/1.0 blue:arc4random()%2/1.0 alpha:1];

        [self.rv addSubview:view2];

    }else if (sender.selectedSegmentIndex == 2){

        UIView *view3 = [[UIView alloc]initWithFrame:CGRectMake(0, 70, 375, 600)];

       

        view3.backgroundColor = [UIColor colorWithRed:arc4random()%2/1.0 green:arc4random()%2/1.0 blue:arc4random()%2/1.0 alpha:1];

        [self.rv addSubview:view3];}}

2.UISlider

①:初始

self.slider = [[UISlider alloc]initWithFrame:CGRectMake(50, 100, 280, 50)];

②:设置最大值

self.slider.minimumValue = 0;

③:设置最小值

self.slider.maximumValue = 1;

④:设置最大值的滑条颜色

self.slider.maximumTrackTintColor = [UIColor blackColor];

⑤:设置最小值的滑条颜色

self.slider.minimumTrackTintColor = [UIColor greenColor];

⑥:右边加图片

self.slider.maximumValueImage = [UIImage imageNamed:@"1.png"];

⑦:左边加图片

self.slider.minimumValueImage = [UIImage imageNamed:@"2.png"];

⑧:圆点颜色

self.slider.thumbTintColor = [UIColor redColor];

⑨:设置圆点图片

self.slider setThumbImage:<#(UIImage *)#> forState:<#(UIControlState)#>

⑩:事件

 [self.rv.slider addTarget:self action:@selector(sliderAction:)

forControlEvents:UIControlEventValueChanged];

// 注意:UIControlEventValueChanged的方法

- (void)sliderAction:(UISlider *)sender{

    NSLog(@"%f",sender.value);// 获取当前滑条所在的值

    self.rv.alpha = sender.value;// 透明度控制}

3.UIImageView

动画:

- (void)viewDidLoad {

    // 父类视图加载完成

    [super viewDidLoad];

    // 做动态图的方法

    [self MoveImageArr];}

- (void)MoveImageArr{

    NSMutableArray *imageArr = [NSMutableArray array];

    for (int i = 0; i < 7; i++)

{       NSString *nameStr = [NSString stringWithFormat:@"%d.tiff",i];

        [imageArr addObject:[UIImage imageNamed:nameStr]];}

    self.rv.mv.animationImages = imageArr;

    // 时间间隔

    self.rv.mv.animationDuration = 0.1;

    // 重复次数

    //    self.rv.mv.animationRepeatCount = 3;

    // 开始动画

    [self.rv.mv.mvstartAnimating];

    // 结束动画

    //    [self.rv.mv. stopAnimating];}

4.UIControl

UIControl 所有控制类的控件直接继承于UIControl

// 核心方法 add target action

// 为控制控件通过 addTarget: action: forControlEvents: 方法来添加事件。

// 通过 removeTarget: action: forControlEvents: 来移除事件。
