Is there anything like a generic list in Cocoa / Objective-C? -


What I really like in C # General list is a list that can contain only one type of object cocoa / Objective-C is something like a generic list? As far as I know only NSArray , which will take an indicator on any object.

In this coco app, it often indicates a weak design.

NSArray is irreversible, so it will not "take any indicators on any object" and potentially you will meet with the right objects before I understand that you are as worried, It's a NSMutableArray , where you think other parts of your code may contain a wrong type of object but look at the coco itself;

Instead, you usually expose a NSArray and expose some methods to modify that array. Some on the lines of: 

  @class Foo: NSObject - (NSArray *) times; - (zero) AdBar: (bar *) bar; - Remove (zero) fence: (bar *) bar; @end

This is usually done by the compiler warning that the wrong things are inserted, and then of course you can logic within -addBar: and You can add - Dump: if you want too.

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%.
