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
