我想在UIAlertController或UIPopoverController中显示UIPickerView,我是iOS新手,请在这里给我一些示例代码.
我搜索了他们但找不到任何满意的答案.我不想在UIActionSheet上这样做,因为它在iOS 9中已被弃用.我也希望它在Swift中而不是在Obj-C中.我尝试了下面的例子,但它不适合我.

解决方法
你的基本代码看起来像:
let alert = UIAlertController(title: title,message: message,preferredStyle: .actionSheet) alert.isModalInPopover = true // Create a frame (placeholder/wrapper) for the picker and then create the picker let pickerFrame = CGRect(x: 17,y: 52,width: 270,height: 100) // CGRectMake(left),top,width,height) - left and top are like margins let picker = UIPickerView(frame: pickerFrame) // set the pickers datasource and delegate picker.delegate = self picker.dataSource = self // Add the picker to the alert controller alert.view.addSubview(picker) //Do stuff and action on appropriate object.
请查看以下答案.
Is there any way to add UIPickerView into UIAlertController (Alert or ActionSheet) in Swift?
