Opening Files - Cocoa

Question

How can I open files from my application? For example, they type a directory in a text box called "inputBox", and they click the open button to open the file.

Answer 1

You can use the NSWorkspace class to open files.

It has several useful methods:

Opening files

– openFile:  
– openFile:withApplication:  
– openFile:fromImage:at:inView:  
– openFile:withApplication:andDeactivate:  
– openTempFile:  
– openURL: 

Their descriptions are given in the docs at https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWorkspace_Class/index.html
