UISegmentedControl的使用
UISegmentedControl是iOS中的分段控件，每个segment都能被点击，相当于继承了若干个button，通常我们会点击不同的segment来接环不同的view
常用方法和属性
initWithItems：独有的初始化方法，用来创建多个分段
setTitle：forSegmentAtIndex：为制定下标的分段设置title
selectedSegmentAtIndex：（property）被选中的segment
tintColor：（property）segmentedControl条的颜色
addTarget：action：forControlEvents：给UISegmentedControl添加事件。其中controlEvent为UIControlEventValueChanged
- (void)viewDidLoad {
[super viewDidLoad];
#pragma mark 布局
/*1.初始化分段控件*/
self.view.backgroundColor = [UIColor colorWithRed:0.94 green:0.50 blue:0.63 alpha:1];
NSArray *segmentedArray = @[@"1",@"2",@"3",@"4"];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentedArray];
//设置frame
segmentedControl.frame = CGRectMake(20, 20, 335, 50);
//四种基本样式（已经被淘汰了）
//指定下标插入标题
[segmentedControl insertSegmentWithTitle:@"学习" atIndex:2 animated:NO];
//替换题目
[segmentedControl setTitle:@"生活" forSegmentAtIndex:1];
[segmentedControl setTitle:@"红色" forSegmentAtIndex:0];
[segmentedControl setTitle:@"蓝色" forSegmentAtIndex:1];
[segmentedControl setTitle:@"灰色" forSegmentAtIndex:2];
[segmentedControl setTitle:@"绿色" forSegmentAtIndex:3];
[segmentedControl setTitle:@"下一页" forSegmentAtIndex:4];
//图片 (会被渲染替换蓝色)
// [segmentedControl insertSegmentWithImage:[UIImage imageNamed:@"6.png"] atIndex:2 animated:YES];
//四种基本样式（已经被淘汰了）
//背景颜色
segmentedControl.tintColor = [UIColor redColor];
[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segmentedControl];
}
#pragma mark 具体方法委托
- (void)segmentAction:(UISegmentedControl *)Seg{
NSInteger Index = Seg.selectedSegmentIndex;
NSLog(@"Index %lu",Index);
switch (Index) {
case 0:
[self selectMyView1];
break;
case 1:
[self selectMyView2];
break;
case 2:
[self selectMyView3];
break;
case 3:
[self selectMyView4];
break;
case 4:
[self selectMyView5];
default:
break;
}
}

//1
- (void)selectMyView1{

[self presentViewController:svc animated:YES completion:^{

UISlider概述
UISlider是iOS中的滑块控件
通常用于控制视频播放进度，控制音量等
它也是继承与UIControl，滑块提供了一系列连续的值，滑块停在不同位置，获取到滑块上的值也不同
UISlider常用属性
minimumValue：设置滑块的最小值
maximumValue：设置滑块的最大值
value：设置滑块的当前值
minimumTrackTinkColor：定义划过区域的颜色
addTarget：action：forControlEvents：给UISlider添加事件，controlEvent为UIControlEventValueChanged
UIImageView常用属性
image：设置图片
animationImages：设置一组动态图片
animationDuration：设置播放一组动态图片的时间
animationRepeatCount：设置重复次数
startAnimating：开始动画
stopAnimating：结束动画
- (void)viewDidLoad {
#pragma mark 第二个页面
[super viewDidLoad];
self.view.backgroundColor = [UIColor orangeColor];
NSArray *segmentedArray = @[@"上一页",@"2",@"3",@"4"];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentedArray];
segmentedControl.frame = CGRectMake(20, 20, 335, 50);
[segmentedControl addTarget:self action:@selector(click:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segmentedControl];
//动态图片添加方法
UIImageView *back = [[UIImageView alloc]initWithFrame:CGRectMake(0, 150, 375, 300)];
back.image = [UIImage imageNamed:@"2.tiff"];
[self.view addSubview:back];
_imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 150, 375, 300)];
NSMutableArray *arr = [[NSMutableArray alloc]init];
for (int i = 1; i < 15 ; i++) {
NSString *str = [NSString stringWithFormat:@"%d.tiff",i];
UIImage *image = [UIImage imageNamed:str];
[arr addObject:image];
}
_imageView.animationImages = arr;
// _imageView.animationRepeatCount = 0;
// _imageView.backgroundColor = [UIColor grayColor];
//动画开始
[self.view addSubview:_imageView];
/*滑块控件*/
UISlider *slider = [[UISlider alloc]initWithFrame:CGRectMake(30, 500, 315, 30)];
// slider.backgroundColor = [UIColor grayColor];
slider.minimumValue = 1;
slider.maximumValue = 5;
//滑动线条颜色
slider.minimumTrackTintColor = [UIColor redColor];
slider.maximumTrackTintColor = [UIColor blackColor];
slider.thumbTintColor = [UIColor blueColor];
//滑块设置
[slider addTarget:self action:@selector(slider1:) forControlEvents:UIControlEventValueChanged];
//垂直的滑块
// slider.transform = CGAffineTransformMakeRotation( M_PI * 0.5 );
//左侧图片
// slider.minimumValueImage = [UIImage imageNamed:@"61"];
[self.view addSubview:slider];
//UISWith
UISwitch *swt = [[UISwitch alloc]initWithFrame:CGRectMake(170, 75, 30, 20)];
[swt addTarget:self action:@selector(swt:) forControlEvents:UIControlEventValueChanged];
swt.on = YES;
[self.view addSubview:swt];
//UIStepper
UIStepper *step = [[UIStepper alloc]init];
step.frame = CGRectMake(170, 110, 30, 20);
[step addTarget:self action:@selector(stepClick:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:step];
UILabel *label = [[UILabel alloc] init];
label.frame = CGRectMake(110, 110, 60, 27);
label.backgroundColor = [UIColor whiteColor];
label.tag = 1;
[self.view addSubview:label];
[step release];
[label release];
[swt release];
[back release];
[slider release];
}
#pragma mark Slider方法实现
//1.滑动改变图片播放速度
- (void)slider1:(UISlider *)slider{
_imageView.animationDuration = 5-slider.value;
[_imageView startAnimating];
NSLog(@"%.2f",slider.value);

//开关
- (void)swt:(UISwitch *)swt{
