你会想看看

 initWithContentsOfURL:
Initializes and returns an NSImage instance with the contents of the specified URL.

- (id)initWithContentsOfURL:(NSURL *)aURL

Parameters
aUrl
The URL identifying the image.
Return Value
An initialized NSImage instance, or nil if the method cannot create an image representation from the contents of the specified URL.
