objective c - Creating bundles in Cocoa -

-

What is the best way to create empty bundles in cocoa? The bundle in OS X is actually nothing but a folder, the only difference is that you have to click on the right content to "Show the contents of the package", right?

Well, I need a bundle in that sense. After that I will put some files of my choice in it, such as a group of plast files. The reason for this is that my file structure (in this, the App Support folder) looks good at the root level.

Related questions: How do I tell OS X that a folder is ending should be treated as a bundle with ".myappFoo"?

The first place for information is Apple Developer Doctor

In the following Whenever any state is correct, the Finder accepts one package:

The directory has a known file name extension: .app, .bundle. Frame, .plugin, .kxt, and so on.

The directory contains an extension that shows some other application claim package type; See the document package.

The directory has its package bit sets.

MyAppfoo is showing as a bundle

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
