1.判断是否支持多窗口,多窗口仅仅支持Ipad和MacOS
[UIApplication sharedApplication].supportsMultipleScenes
2.判断是否为catalyst环境
[[NSProcessInfo processInfo] isMacCatalystApp]
3.关于MacOS左上角的Menu
- (void)buildMenuWithBuilder:(id<UIMenuBuilder>)builder API_AVAILABLE(ios(13.0))
[[UIMenuSystem mainSystem] setNeedsRebuild];
4.鼠标右击事件添加
if (@available(iOS 13.0, *)) {
UIContextMenuInteraction *contextMenuInteraction = [[[UIContextMenuInteraction alloc] initWithDelegate:self] autorelease];
[self.view addInteraction:contextMenuInteraction];
}
- (UIContextMenuConfiguration *)contextMenuInteraction:(UIContextMenuInteraction *)interaction configurationForMenuAtLocation:(CGPoint)location
{
return nil
}
5.Mac中导入本地文件.图片等
UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:@[@"public.plain-text",@"public.png",@"public.jpeg",@"com.compuserve.gif",@"public.tiff",@"com.microsoft.bmp",@"dyn.age81k6xg",@"com.microsoft.excel.xls",@"com.microsoft.word.doc",@"com.apple.property-list",@"com.adobe.pdf",@"public.rtf",@"public.audiovisual-content",@"com.apple.rtfd"] inMode:UIDocumentPickerModeImport];
documentPicker.delegate = self;
documentPicker.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:documentPicker animated:YES completion:nil];
- (void)documentPicker:(UIDocumentPickerViewController *)controller didPickDocumentsAtURLs:(NSArray <NSURL *>*)urls API_AVAILABLE(ios(11.0))
{
NSURL *uurl = urls[0];
NSString *urlss = [uurl absoluteString];
NSString *typeStr = [[[urlss componentsSeparatedByString:@"/"] lastObject] pathExtension];
NSString *fileType = [typeStr uppercaseStringWithLocale:[NSLocale currentLocale]];
}
6.获得状态栏的高度.present出来控制器后,需要知道状态栏的高度(如图红框中).可以通过navigationBar来获得. self.navigationBar.frame.
7.通过UIDocumentPickerViewController导入Mac中的文件，报错ERROR: Unable to display open panel: your app is missing the User Selected File Read app sandbox entitlement. Please ensure that your app's target capabilities include the proper entitlements.
需要打开sandbox read/write 权限
