如何在iOS中以编程方式创建范围滑块？ [英] How to Create Range Slider Programatically in iOS?

问题描述

我想创建一个范围滑块。但是我在同一个位置分配2个滑块然后只有1个工作。我找到了一些外部API来创建Slider。有没有办法在iOS编程中创建范围滑块。

I want to create a range slider. but wahen I assign 2 sliders in same position then only 1 is working. I found some External APIs to create Slider. Is there any way to create Range slider in iOS Programatically.

这是我的代码..

  CGRect frame = CGRectMake(20, 330, 300, 60);

slider1 = [[UISlider alloc] initWithFrame:frame];
[slider1 addTarget:self action:@selector(sliderActionMin:) forControlEvents:UIControlEventValueChanged];
[slider1 setBackgroundColor:[UIColor clearColor]];
slider1.minimumValue = 0.0;
slider1.maximumValue = 55.0;
slider1.continuous = YES;
slider1.value= 16
slider1.contentMode=UIViewContentModeScaleToFill;
[self.view addSubview:slider1];


slider2 = [[UISlider alloc] initWithFrame:frame];
[slider2 addTarget:self action:@selector(sliderActionMin:) forControlEvents:UIControlEventValueChanged];
[slider2 setBackgroundColor:[UIColor clearColor]];
slider2.minimumValue = 0.0;
slider2.maximumValue = 55.0;
slider2.continuous = YES;
slider2.contentMode=UIViewContentModeScaleToFill;
slider2.value=[SingletonClass sharedSingleton].minAge;
[self.view addSubview:slider2];

推荐答案

您正在另一个滑块上方添加一个滑块。所以根据Cocoa-Touch标准，只有Top（新添加的）滑块将检测所有事件。当您在相同的帧值上添加两个滑块时，第一个滑块将是不可触摸的。

You are adding one slider above another slider.So As per Cocoa-Touch standards, Only Top (newly added) slider will detect all events. First slider will be untouchable as you added both slider on same frame value.
