折腾：
期间，去写代码，结果
感觉是：
去实现：
ActionSheetCustomPickerDelegate <UIPickerViewDelegate, UIPickerViewDataSource>
的时候，
Xcode时不时的就崩溃了：
并且编译出错
Command failed due to signal: Segmentation fault: 11

注意到，此处就是我正在编辑的文件：
CompileSwift normal i386
/CustomerDetailViewController.swift
出的错。
后来把：
// func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
// gLog.verbose("pickerView=\(pickerView), row=\(row), component=\(component)")
//
// var curTitle = ""
//
// switch component {
// case 0:
// curTitle = gCurUserItem.customerSourceList[row].text
// case 1:
// let firstLevelSelectedRowIndex = pickerView.selectedRowInComponent(0)
// gLog.verbose("firstLevelSelectedRowIndex=\(firstLevelSelectedRowIndex)")
// curTitle = gCurUserItem.customerSourceList[firstLevelSelectedRowIndex].subSourceList[row]
// default:
// break
// }
//
// gLog.verbose("curTitle=\(curTitle)")
//
// return curTitle
// }
注释掉，就可以正常编辑，没有错误了。。。

但是没有解决问题啊。
我还是要用这些protocol的啊。。
后来的后来，发现是自己的语法错误：
某个值的值的值中的某个属性，还没来得及加上，Xcode的代码格式化就崩溃了：
导致没注意到错误
改为：
// curTitle = gCurUserItem.customerSourceList[firstLevelSelectedRowIndex].subSourceList[row]
curTitle = gCurUserItem.customerSourceList[firstLevelSelectedRowIndex].subSourceList[row].text
其中的text是自己的定义的类中的属性：
即可解决问题，可以正常编译。
