我想在Main.storyboard
上展示所有这些:
但是键Position

将出现在第一个TableViewController上,键functional
、ImageFace
和Phone
必须出现在第二个TableViewController上
为此,我做了如下:

根据您的plist结构:
Shared.instance.employees[indexPath.row].details
details
是一组字典。你把它当作一本字典
编辑:最初的问题是正确的。。。多种解决方法(如您所见/所做)。另一种可能有用也可能无用的选择:
struct EmployeeDetails {
let functionary: String
let imageFace: String
let phone: String
init(dictionary: [String: Any]) {
self.functionary = (dictionary["Functionary"] as? String) ?? ""
self.imageFace = (dictionary["ImageFace"] as? String) ?? ""
self.phone = (dictionary["Phone"] as? String) ?? ""
}
}
struct Employee {
let position: String
let name: String
let details: [EmployeeDetails] // [String:Any]
init(dictionary: [String: Any]) {
self.position = (dictionary["Position"] as? String) ?? ""
self.name = (dictionary["Name"] as? String) ?? ""
let t = (dictionary["Details"] as? [Any]) ?? []
self.details = t.map({EmployeeDetails(dictionary: $0 as! [String : Any])})
}
}
struct Shared {
static var instance = Shared()
var employees: [Employee] = []
}
然后,您可以执行原始操作:
if let url = Bundle.main.url(forResource: "directory", withExtension: "plist"), let array = NSArray(contentsOf: url) as? [[String:Any]] {
Shared.instance.employees = array.map{Employee(dictionary: $0)}
}
然后通过以下方式访问数据:
let anEmployee = Shared.instance.employees[0]
print("Name:", anEmployee.name)
print("Position:", anEmployee.position)
print("Detail 0 Functionary:", anEmployee.details[0].functionary)
print("Detail 0 ImageFace:", anEmployee.details[0].imageFace)
print("Detail 0 Phone:", anEmployee.details[0].phone)
// or
anEmployee.details.forEach({
print("Functionary:", $0.functionary)
print("ImageFace:", $0.imageFace)
print("Phone:", $0.phone)
})
举个例子
有关工作示例,请参阅。Umm。。。好啊你明白我的答案了吗?当
是字典的数组时,您将细节
视为一个字典
。请参见我的中的编辑answer@ArnonRodrigues-看来你已经上路了。我更新了我的答案,稍微更改了原始结构,使您能够更“一致”地访问数据。也许更好,也许不是:)@Arnnrodrigues-你很接近。。。我继续写了一个GItHub repo,这样你就可以看一看——比试图解释什么要容易得多:)根据调试/错误消息,你的故事板中似乎有什么东西没有正确连接。在Interface Builder中仔细检查分配给每个UITableViewController的类。如果您看到的是表2,但它是“空的”,那么它的行数是否正确?这听起来也像是情节提要中的混乱。。。细胞原型可能缺少ID?是的,IB中的东西可能会“混乱”。打开你的主。情节提要。。。选择“工作人员”场景。。。将类(在Identity Inspector下)从Page2
更改为普通的UITableViewController
。。。按Command+B以生成。。。再次选择工作人员场景。。。将类更改回第2页。。。运行应用程序,然后。。。。呜呼?
