要在macOS应用程序中的所有窗口上迭代,我使用enumerateWindows(options:using:)
如下:
NSApplication.shared.enumerateWindows(options: .orderedFrontToBack, using: {
(window: NSWindow, stop: UnsafeMutablePointer<ObjCBool>) in
if let vc = window.contentViewController as? SomeCustomViewController {
if someCondition {
stop = true // “Cannot assign to value: 'stop' is a 'let' constant”
}
}
})
我想在满足
someCondition
时停止枚举,但无法将UnsafeMutablePointer<ObjCBool>
设置为true
:Xcode告诉我stop
是一个let
常量。我做错什么了?
最佳答案
stop
是指针,必须设置pointee
stop.pointee = true
