我们都知道，iOS的图标是需要自己设置的，如下：
image.png
有时候，UI给我们的icon很有可能缺了某一个，或者说某一个尺寸不对，有一个办法是找UI重新给我们重新做一下尺寸，但是有可能需要等一段时间，而我们是急着马上要用的，我们可以自己生成嘛。这就是AppIcon应用的作用，只要一张图片，就能够生成所有所需的icon，再也不用求人了。
使用SwiftUI编写UI界面
以前没有写过macOS的软件，但是SwiftUI会写，于是，我用SwiftUI写了界面。
直接上UI界面全部代码。
struct ContentView: View {
@State private var path = ""
@State private var alertShow = false
@State private var errorAlertShow = false
@State private var choiceDevice = ""
@State private var errorMSG = ""
@State private var image: NSImage?
@State private var dragOver = false
var body: some View {
VStack {
Group {
Text(TextTools.Tips)
.padding()
Spacer()
Image(nsImage: image ?? NSImage(named: "add")!)
.resizable()
.scaledToFit()
.frame(width: 250, height: 250)
.onTapGesture {
showChoiceImagePanel()
}
.onDrop(of: ["public.file-url"], isTargeted: $dragOver, perform: { providers -> Bool in
providers.first?.loadDataRepresentation(forTypeIdentifier: "public.file-url", completionHandler: { (data, error) in
if let data = data, let path = NSString(data: data, encoding: 4),
let url = URL(string: path as String) {
let image = NSImage(contentsOf: url)
self.image = image
}
})
return true
})
.alert(isPresented: $errorAlertShow) { () -> Alert in
Alert(title: Text(TextTools.AlertTitle),
message: Text(errorMSG),
dismissButton: .default(Text(TextTools.Sure)))
}
Spacer()
}
HStack {
Button(TextTools.OpenPath) {
openImagePath()
}.background(Color.green.cornerRadius(5)).padding()
TextField(TextTools.Path, text: $path)
.padding()
.disabled(true)
Button(TextTools.Choice) {
showImageSavePanel()
}.background(Color.green.cornerRadius(5)).padding()
}
HStack {
Button(TextTools.iPhone) {
guard checkError() else {
return
}
choiceDevice = TextTools.iPhone
alertShow.toggle()
}.background(Color.green.cornerRadius(5))
Spacer()
Button(TextTools.iMac) {
guard checkError() else {
return
}
choiceDevice = TextTools.iMac
alertShow.toggle()
}.background(Color.green.cornerRadius(5))
Spacer()
Button(TextTools.iWatch) {
guard checkError() else {
return
}
choiceDevice = TextTools.iWatch
alertShow.toggle()
}.background(Color.green.cornerRadius(5))
}.padding()
.alert(isPresented: $alertShow) { () -> Alert in
Alert(title: Text(TextTools.AlertTitle),
message: Text(TextTools.AlertMSG1 + choiceDevice + TextTools.AlertMSG2),
primaryButton: .default(Text(TextTools.Sure),
action: {
if choiceDevice == TextTools.iPhone {
saveIPhoneIcon()
} else if choiceDevice == TextTools.iMac {
saveMACIcon()
} else if choiceDevice == TextTools.iWatch {
saveWatchIcon()
}
}),
secondaryButton: .default(Text(TextTools.Cancel)))
}
}.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
}
}
是的，你没有看错，UI界面就这么些代码,最终运行结果如下:
image.png
然后把剩下的逻辑处理相关代码添加上去,最终项目完整代码:https://github.com/flywo/AppIcon
