xcode4 - How do you sort the source tree in project navigator in Xcode 4? -

-

In Xcode 3, it was relatively easy to sort the source tree by name (see answer for more details). However, I have not figured out how to sort files and groups in Xcode 4 without dragging them manually.

There is no way for Project Navigator in addition to drag and drop, possibly because it will be very easy to wipe out your careful organization.

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.
