问题 I use below code for open image with NSOpenPanel but doesn't work //panel=NSOpenPanel NSString *imgg = [NSString stringWithFormat:@"%@",panel.URL]; self.imgUser.image=[NSImage imageNamed:imgg]; 回答1: The problem is that +[NSImage imageNamed:] doesn't load an image by URL.

There are a large number of

Since it makes perfect sense to show an NSOpenPanel as a sheet in a document-based app, I wanted to do that but it is crucial that the current thread is blocked, so no subsequent code can be called until the new media file is chosen. I can't find a way to present this
