如何迭代 macOS 应用程序的 windows 直到满足条件?

How to iterate over a macOS app’s windows until a condition is met?

为了遍历我的 macOS 应用程序中的所有 windows,我使用 enumerateWindows(options:using:) 像这样:

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,但我无法将UnsafeMutablePointer<ObjCBool>设置为true:Xcode告诉我stop 是一个 let 常量。

我做错了什么?

stop是一个指针,你要设置pointee

stop.pointee = true
