我们正在开发一个菜单栏项应用程序,我很想编写一个NSAlert
类别,在 中显示警报NSPopover
,显示在NSStatusItem
.
到目前为止,该类别实现了以下新方法:
- (void) runAsMenuItemPopUpWithCompletionBlock:(NSAlertCompletionBlock)block {
// Get content view of NSAlert
NSView *alertContentView = [self.window contentView];
// Ask the menu item to show the view as a NSPopOver
[[GFMenuItem sharedInstance] popOverView:alertContentView];
// (...) Handle response with callback
}
但是打开警报
NSAlert *alert = [NSAlert alertWithMessageText:@"Learn more?" defaultButton:@"Learn more" alternateButton:@"Cancel" otherButton:nil informativeTextWithFormat:@"Do you want to view detailed information?"];
[alert runAsMenuItemPopUpWithCompletionBlock:nil];
结果如下可视化:
问题是第三个空按钮,帮助按钮和复选框,没有设置显示。如果没有设置它们,关于如何摆脱它们的任何想法?
