011&012_UISwitch/UISlier/UIProgressView 开关、滑动条、进度条

UISwitch:width和height不可以改变（80,40）

UISlider和ProgressView的高度不可以改变：40

UISwitch：开关

UISlider：调节音量等

ProgressView:没有方法，进度条，用于加载等；

定义类代码：

#import
<UIKit/UIKit.h>

@interface ViewController :
UIViewController

{

    UIProgressView* _processView;

    UISlider* _slider;

    UISwitch* _mySwitch;

    

}

@property(retain,nonatomic)UIProgressView*
processView;

@property(retain,nonatomic)UISlider*
slider;

@property(retain,nonatomic)UISwitch*
mySwitch;

@end
