NSSavePanel在优胜美地崩溃 [英] NSSavePanel crashes on Yosemite

问题描述

我正在使用 NSSavePanel 保存图像.

我使用了 IKSaveOption 添加到NSSavePanel. 当保存"面板尝试打开工作表窗口时，它崩溃，提示-

I have used IKSaveOption which gets added to the NSSavePanel. When save panel tries to open the sheet for window it crashes saying -

***-[IKSaveOptionsContainer _didChangeHostsAutolayoutEngineTo:]，/SourceCache/AppKit/AppKit-1343.14/Layout.subproj/NSView_Layout.m:577中的断言失败 -如果_didChangeHostsAutolayoutEngineTo:YES，应将自动调整大小的掩码转换为约束.

*** Assertion failure in -[IKSaveOptionsContainer _didChangeHostsAutolayoutEngineTo:], /SourceCache/AppKit/AppKit-1343.14/Layout.subproj/NSView_Layout.m:577 - Should translate autoresizing mask into constraints if _didChangeHostsAutolayoutEngineTo:YES.

我正在遵循以下代码:

NSSavePanel *savePanel = [NSSavePanel savePanel];
    [savePanel setDirectoryURL:[NSURL URLWithString:NSHomeDirectory()]];
    [savePanel setDelegate:self];
    [savePanel setPrompt:NSLocalizedString(@"save",nil)];
    [savePanel setAllowedFileTypes:[NSArray  arrayWithObjects:@"png",@"jpeg",nil]];
      IKSaveOptions * opt = [[IKSaveOptions alloc] initWithImageProperties:nil
                                                          imageUTType:(NSString *)kUTTypePNG];
    [opt addSaveOptionsAccessoryViewToSavePanel:savePanel];
    [savePanel setExtensionHidden:NO];

   [savePanel beginSheetModalForWindow:self.window completionHandler:^(NSInteger result){.....
}

此代码可在Maverick中使用，但不能在优胜美地上使用.新的OS API是否有任何布局更改?

This code works in Maverick, but not on Yosemite. Are there any layout changes in the new OS API?

推荐答案

Update2:该解决方案很简单.

Update2: The solution turns out to be simple.

[self.saveOptions addSaveOptionsAccessoryViewToSavePanel:savePanel];
savePanel.accessoryView.translatesAutoresizingMaskIntoConstraints = YES;

更新:以下解决方法不会更改文件名的扩展名，并且根据您保存文件的方式，可能不会接受新格式的请求.

Update: The below workaround does not change the filename's extension and depending on how you save the file, the new format request may not be honored.

我找到了一种解决方法，并向Apple(20595916)提交了一个错误.解决方法不是很好，因为超级视图的大小可能不足，并且会裁剪图像选项的控件.

I found a workaround, and I filed a bug with Apple (20595916). The workaround isn't great because the superview's size might be inadequate and clip the controls for the image options.

NSView* view = [[NSView alloc] initWithFrame:NSMakeRect(0, 0, 400, 200)];
view.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;
savePanel.accessoryView = view;

[self.saveOptions addSaveOptionsToView:view];
