UIStepper 加减法器：

<pre name="code" class="objc"> UILabel * leb = [[UILabel alloc]initWithFrame:CGRectMake(100, 200, 100, 100)];    leb.backgroundColor = [UIColor redColor];    self.label = leb;    [self.window addSubview:leb];    // ==========    UIStepper * stepper = [[UIStepper alloc]init];   // [stepper setCenter:self.window.center];    stepper.frame = CGRectMake(100, 100, 200, 200);    stepper.tintColor = [UIColor blueColor];    stepper.value = 10;    [stepper setMaximumValue:15.0];    [stepper setMinimumValue:0.0];        //[stepper setValue:5.5];    [stepper setStepValue:1];    // 是否循环    [stepper setWraps:YES];    // 设定stepper可以按住不放连续更改数值    [stepper setContinuous:YES];    [stepper addTarget:self action:@selector(steepValueschanged:) forControlEvents:UIControlEventValueChanged];    [self.window addSubview:stepper];

事件紧迫，不写具体的了，API自己搞~~~~
