设置备用应用程序图标将返回错误3072：“操作已取消”在iOS 10.3中 [英] Setting Alternate App Icon returns error 3072: "The operation was cancelled" in iOS 10.3

问题描述

我正在尝试在 iOS 10.3 中为我的应用设置备用图标，但每次调用方法时Xcode都会返回：

I am trying to set the alternate icons for my app in iOS 10.3, but every time I call the method Xcode returns:

错误域= NSCocoaErrorDomain代码= 3072操作已取消。

Error Domain=NSCocoaErrorDomain Code=3072 "The operation was cancelled."

我正在使用 @KlimczakM 的答案这个帖子设置图标（下面调用的 specifyIcon 方法），但我使用自己的方法从设置加载首选图标：

I am using @KlimczakM's answer from this post to set the icon (the specifyIcon method called below) but I am using my own method to load the preferred icon from settings:

let iconSetting = userDefaults.string(forKey: "appIconSetting")
print("The icon setting is: \(iconSetting ?? "error getting appIconSetting.")")

switch iconSetting! {
case "white":
    specifyIcon(nil)
case "dark":
    specifyIcon("dark")
case "text":
    specifyIcon("text")
case "textdark":
    specifyIcon("textdark")
case "rainbow":
    specifyIcon("rainbow")
default:
    specifyIcon(nil)
    print("ERROR setting icon.")
}

func specifyIcon(_ icon: String?) {
    //(@KlimczakM's answer)
}

在我的 Info.plist中我有五个图标; 白色，深色， rainbow ， text ， textdark ：

In my Info.plist I have five icons; white, dark, rainbow, text, and textdark:

所有这些图标都包含在我的应用包内名为resources的文件夹中的PNG文件中。

All of these icons are contained as PNG files in a folder called "resources" inside my app bundle.

我该如何解决这个问题？

How can I fix this issue?

推荐答案

我得到了这个错误有两个原因，

I was getting this error because of two reasons,

• 首先，我没有做将文件添加到'ProjectNameFoo'通过将png文件添加到项目中。否则它不起作用。之后它开始看到图标。



• 其次，我收到此错误是因为我在 viewDidLoad 之后尝试更改图标。我不是为什么，但它给了我同样的错误。当我像下面的代码一样尝试延迟时它会在我给出的任何时间内工作。

• First, I didn't do "Add Files to 'ProjectNameFoo'" by adding png file to project. Otherwise it didn't work. After that it started to see icon.

• Secondly, I was getting this error because I was trying to change icon after in viewDidLoad. I don't why but it was giving me same error. When I try with a delay like the code below it was working whatever second I gave.

override func viewDidLoad() {
    super.viewDidLoad()

    delay(0.01) {
        if foo().isFoo() {
            print("")

            self.changeIcon(name: "ColdRabbit")
        }
        else {
            print("")
        }
    }
}

func delay(_ delay:Double, closure:@escaping ()->()) {
    let when = DispatchTime.now() + delay
    DispatchQueue.main.asyncAfter(deadline: when, execute: closure)
}
