UIProgressView UISlider UISegmentedControl

UISegmentedControl是开发中经常会使用到，所以刚刚在学习的时候也重点的看了下该控件

进度条和滑动条一半很少会使用到（下载的时候会经常使用到该属性），android的进度条和滑动的设置比ios复杂很多

先上图

1，进度条

    /**进度条的使用
     1.创建UIProGressView对象
     2，创建定时器
     3，将定时器的值与进度条的长度关联setProgress
     4，释放对象
    
    */
    //进度条的使用UIProgressView
    progress=[[UIProgressView alloc]initWithFrame:CGRectMake(50, 250, 300, 150)];
    progress.progressViewStyle=UIProgressViewStyleDefault;
    progress.progressTintColor=[UIColor redColor];//设置进度条的颜色，下面设置了图片会覆盖掉该颜色
    progress.trackTintColor=[UIColor grayColor];//设置背景柱状图的颜色
    progress.progressImage=[UIImage imageNamed:@"login.png"];//图片替代进度条
    progress.transform=CGAffineTransformMakeScale(1.0f, 100.0f);//设置进度条的高度
    [self.view addSubview:progress];
    [progress release];

//    //创建定时器，一秒执行一次
    time=[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(show) userInfo:nil repeats:1];
    proValue=1.0;

方法：

//点击事件
-(void)show{
//    NameBean *bean=[[NameBean alloc]init];
//    bean.name=@"百合不是茶next";
//    bean.address=@"湖南next";
//    bean.age=122;
//    
//    ViewController *vc =[[ViewController alloc]init];
//    [delegate getOneNameBean:bean];//设置代理数据
//    [self.navigationController pushViewController:vc animated:1];
//    
//    [bean release];
//    [vc release];
    
    ++proValue;
    
    if (proValue>10) {
        //停止定时器
        [time invalidate];
        //计数器停止后，进度条重置
        [progress setProgress:0];
    }else{
    //进度条停止前进
        [progress setProgress:proValue/10];
    
    }

注意：

进度条的方法使用了定时器，事件处理也是在定时器中操作的

 NSTimer ＊time=[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(show) userInfo:nil repeats:1];

2，滑动条

   /**
     滑动条 UISlider
     1,创建UISlider的对象
     2，指定滑动区间
     3，设置滑动事件
     4，释放
     
     */
    
    slider=[[UISlider alloc]initWithFrame:CGRectMake(50, 300, 300, 150)];
    //指定最小值
    slider.minimumValue=0;
    //指定最大值
    slider.maximumValue=100;
    //指定可变最大值50
    slider.value=50;
    //设置点击实现
    [slider addTarget:self action:@selector(getSliderValue) forControlEvents:UIControlEventValueChanged];
    
    
    [self.view addSubview:slider];
    [slider release];

方法

//滑动条的事件方法。
-(void)getSliderValue{

    NSLog(@"滑动条的值是＝%f",slider.value);
    
//    [progress setProgress:slider.value];
}

运行：滑动时：

2015-12-20 16:04:01.755 viewDemo[1125:189580] 滑动条的值是＝16.666666

2015-12-20 16:04:01.772 viewDemo[1125:189580] 滑动条的值是＝17.222218

2015-12-20 16:04:01.795 viewDemo[1125:189580] 滑动条的值是＝17.444443

2015-12-20 16:04:01.800 viewDemo[1125:189580] 滑动条的值是＝17.444443

3，分隔栏

   
    /**
     分格拦控件UISegmentControl
     */
    
    segment=[[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects:@"买入",@"卖出",nil]];
    segment.frame=CGRectMake(50, 500, 300, 100);
    segment.selectedSegmentIndex=1;//默认选中第一个
//    [segment setImage:[UIImage imageNamed:@"login.png"] forSegmentAtIndex:1];//设置选中的背景图片
//    segment.segmentedControlStyle=UISegmentedControlSegmentCenter;//设置风格
    
    //插入数据
//    [segment insertSegmentWithImage:[UIImage imageNamed:@"login.png"] atIndex:1 animated:0];
    
    //背景图片的设置
    [segment setBackgroundImage:[UIImage imageNamed:@"login.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [segment setBackgroundImage:[UIImage imageNamed:@"bk.jpg"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    //点击事件
    [segment addTarget:self action:@selector(getSegment) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:segment];
    [segment release];

点击事件

//分格拦控件事件
-(void)getSegment{
    int n=segment.selectedSegmentIndex;
      [segment setBackgroundImage:[UIImage imageNamed:@"bk.jpg"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    
    NSLog(@"%d,标题是＝％@",n,segment);
}

设置选中背景图片

    [segment setBackgroundImage:[UIImage imageNamed:@"bk.jpg"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

设置未选中背景图片

    [segment setBackgroundImage:[UIImage imageNamed:@"login.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
