macos - NSButton 在 setTransparent:NO setEnabled:YES 之后高亮显示

Question

我有 2NSButton秒，两者都是带边框的瞬时按下按钮。我有一个主窗口，其他视图被换入和换出。这两个按钮位于主窗口自定义视图（下一个，上一个）中，有助于在视图中导航。

当我在下一个按钮的帮助下到达 2 视图时，我使上一个按钮启用并可见。因此，如果此时我按下上一个按钮，第一个视图将被交换，我使上一个按钮透明并启用。

此时，如果您按下下一个按钮导航到第二个视图，则将换入第二个视图并再次显示上一个按钮。但在这里突出显示。我怎样才能摆脱这个？

I hope you will get some better answers, but a general technique that I have found to work in cases like this is to wait with enable/disable actions until things have settled down for the new configuration of the views.

After all (if I have read your description correctly), you are hiding a button in the middle of its own action handler.

Postponing this is easily obtained by dispatching your enable/disable code on the next (or, more correctly, a later) invocation of the run loop of the main thread:

dispatch_async(dispatch_get_main_queue(), ^{

    // Enable or disable your buttons here.
});

As a solution it is somewhat of a hack, but on the other hand, waiting until your main view is no longer in a state of flux before you re-configure your navigation UI is not a bad approach.
