UISwitch的用法

//公开手机号的开关
    UISwitch * phoneSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(bgimage.width-95, (50.0f-30.0f)/2+1, 50, 30)];
    phoneSwitch.on = YES;
    [phoneSwitch addTarget:self action:@selector(switchIsChange:) forControlEvents:UIControlEventValueChanged];
    [bgimage addSubview:phoneSwitch];
    [phoneSwitch release];
//UISwitch继承自UIControl，能够经过UISwitch的ison方法，来判断它是不是选中的。
