Question

我有以下方法：

- (IBAction) selectPatientDirectory: (id)sender {
    NSOpenPanel *panel = [NSOpenPanel openPanel];

    panel.canChooseFiles          = NO;
    panel.canChooseDirectories    = YES;
    panel.allowsMultipleSelection = NO;

    [panel beginWithCompletionHandler: ^(NSInteger result) {
        if (result == NSFileHandlingPanelOKButton) {

            ALBuild *patient = [ALBuild new];
            [patient buildFrom: panel.URLs [0]];

        }
    }];
}

这种方法适用于小牛队（以及更低级别）。但是，当它在Yosemite上运行并且patient buildFrom:方法执行时间超过大约15秒时，我在控制台上收到以下警告：

我完全不知道为什么会这样。如果patient buildFrom:快速运行，则不会生成警告。优胜美地有新的超时问题吗？任何有关此问题的帮助将不胜感激。我正在使用：

Xcode: 6.2
OS X:  10.10.2

周围的工作：

如果您以模态方式运行面板，则不会收到警告：

- (IBAction) selectPatientDirectory: (id)sender {

    NSOpenPanel *panel = [NSOpenPanel openPanel];

    panel.canChooseFiles          = NO;
    panel.canChooseDirectories    = YES;
    panel.allowsMultipleSelection = NO;

    if ([panel runModal] == NSFileHandlingPanelOKButton) {
        ALBuild *patient = [ALBuild new];
        [patient buildFrom: panel.URLs [0]];
    }
}

NSOpenPanel在Yosemite上生成控制台警告
