我正在使用一个 4 UIButton
,它显示相同UIPickerView
但NSArray
每个按钮出现不同的 (4)。使用 4bool
让UIPickerView
决定加载哪个row's text
,抓取哪个。按钮方法只包括四个bool
属性,将三个设置为false
,将正确的一个(点击按钮)设置为true
。然后UIViewAnimateWithDuration
被称为带来了UIPickerView
(打印在UIView
- 为两者UIPickerView
并UIToolbar
一起工作)。除了一个按钮之外,所有按钮都可以正常工作(无论我带来/关闭 UIPickerView 多少次)(即使它是按第一-中间-最后-任意顺序按下的)。Xcode 抛出以下异常:
我做了什么:
- 删除按钮,创建一个新的
- 尝试了创建按钮的故事板/控制器方法
- 使用按钮添加方法
addtarget
- 使用情节提要的方法链接按钮
所以我要问的是,是否有人能看到我在调试器抛出的异常中看不到的任何东西:(sportCenter 是 aNSObject
并且它没有在这个控制器中导入 - 也试过了!)
