在UIActivityViewController中使用名称共享数据

Question

我在我的应用中添加了共享功能，以分享名称，价格，数量和描述等数据。这就是我实现它的方式......

let prodObj = newProdDetails[indexPath.row]
let name = prodObj.name
let price = prodObj.mrp
let qty = prodObj.quantity
let description = prodObj.descriptions

let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  [name, price, qty, description], applicationActivities: nil)
self.present(activityViewController, animated: true, completion: nil)

当我在whatsapp中这样分享时，接收者得到的东西就像Box，6,500（如果名称是盒子，数量是6和价格500）。

但是当我发送邮件时，我希望接收方能够获得类似

的内容

Name: Box

Quantity: 6

Price: 500

而不仅仅是Box，6,500

我怎样才能做到这一点......？

Answer 1

发送活动项目的字符串，例如"Name: \(name)"

let prodObj = newProdDetails[indexPath.row]
if let name = prodObj.name,
    let price = prodObj.mrp,
    let qty = prodObj.quantity,
    let description = prodObj.descriptions  {

    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  ["Name: \(name)", "Price: \(price)", "Quantity: \(qty)", "Description: \(description)"], applicationActivities: nil)
    self.present(activityViewController, animated: true, completion: nil)
}

Answer 2

只需运行代码：

    let name = "javed"
    let price = 700
    let qty = 77

    let finalString:String = "Name:" + name + "\n" + "Quantity:" + String(qty) + "\n" + "Price:" + String(price)
    print(finalString)

<强>结果：

或者你已经有了字符串值：

Answer 3

您可以尝试这样：

let prodObj = newProdDetails[indexPath.row]
let name = prodObj.name
let price = prodObj.mrp
let qty = prodObj.quantity
let description = prodObj.descriptions

let finalString:String = "Name:" + name + "\n" + "Quantity:" + qty + "\n" + "Price:" + price 

let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  [finalString], applicationActivities: nil)

<强>结果：

Name: Box

Quantity: 6

Price: 500

测试100％正常工作

Answer 4

你可以这样做。

let share : String = "Name: \(name) \nQuantity: \(qty) \nPrice: \(price)" 

let activityViewController:UIActivityViewController = UIActivityViewController(activityItems:  [share], applicationActivities: nil)

发生的事情不是传递单个属性，比如名称价格，而是使用（键值对，因此您知道哪个值与哪个键关联）创建了一个字符串或字典数组，然后传递整个数组，您还可以检查是否存在值，然后仅将其添加到最终数组（根据您的要求）

let prodObj = newProdDetails[indexPath.row]

let name = prodObj.name ?? "" //this means if name is nil it will set empty string 
let price = prodObj.mrp ?? 0 
let qty = prodObj.quantity ?? 0
let description = prodObj.descriptions ?? ""

//create array from the data you get you can create a string like below
let finalArrayString =  ["Name: \(name)", "Price: \(price)", "Quantity: \(qty)", "Description: \(description)"]

//or create an array of the dictionary for using it late

let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: finalArrayString , applicationActivities: nil)

另外，在使用之前检查你的prodObj是否为零，你可以返回它的nill（根据你的要求）

还要理解为什么在从StackOverflow复制粘贴代码之前，因为它会节省你的时间，
