我有一个被定义为错误的变量,这就是我打印它时的样子:
ArrayList<Rent> rents = loadRents();
String[] header = new String[] {"Star date", "End date", "Room number","Guest name", "Guest lastname", "Guest ID card"};
Object[][] show = new Object[rents.size()][header.length];
for (int i = 0; i < rents.size(); i++) {
Rent r = rents.get(i);
show[i][0] = r.getDateStart();
show[i][1] = r.getDateEnd();
show[i][2] = r.getRoomNumber();
show[i][3] = r.getGuestName();
show[i][4] = r.getGuestLastname();
show[i][5] = r.getGuestIDCard();
DefaultTableModel tableModel = new DefaultTableModel(show, header);
tblRents = new JTable(tableModel);
tblRents.setRowSelectionAllowed(true);
tblRents.setColumnSelectionAllowed(true);
tblRents.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
tblRents.setDefaultEditor(Object.class, null);
tblRents.setAutoCreateRowSorter(true);
我想要做的是获得-2的代码...我该怎么做?
答案 0 :(得分:4)
您可以先打开可选的error
并比较-2
案例。
if let error = error {
switch error._code {
case LAError.userCancel.rawValue: // or -2 if you want
// do something
default:
break
}
}

您只需要将错误转换为LAError(本地身份验证错误)并切换其代码属性:
if let error = error as? LAError {
switch error.code {
case .userCancel:
print("userCancel")
default:
print("unknown error")
}
}

我确定您要使用.border
上的.border{
color: #E9C8FF;
}
属性:

我写了这个小扩展名:
extension Error {
var errorCode:Int? {
return (self as NSError).code
}
}
使用:
if error.errorCode == -2 {
//some code
}
