Where are the UIKit Framework implementation files located?
(2 answers)
Closed 6 years ago.
I was just wondering if there is a way to read the internal implementation of Apple's API on ios? For example, is there a way I can see how "setNeedsDisplay()" function of UIView is implemented internally? I think this will help me understand how the code actually works.
The source code to the Apple frameworks is not publicly-available. You can disassemble the framework code, but unless you're really good with assembly language, you probably won't learn much.

Swift: print() vs println() vs NSLog()
(6 answers)
Closed 7 years ago.
What is the difference between NSLog(), println, and print?
From my experience and understanding, they all write in the Console/Debugging area but why is there the change in Swift v1.2 and v2.0?
If you use 2.0 then print will offer more functionality, but they are still the same thing. Please refer to the documentation to see the added functionality.

Also don't use NSLog if you are using Swift

api for showing native calculator in iOS app

Is it possible to start the iPhone calculator from within an iOS app?
I find it really annoying to have to leave an app and open the calculator just to "trig out" a right triangle and then return to the original app. I have a calculator class of my own however I would prefer not to reinvent the wheel for my app; especially with all the edge cases involved with Trig.
Can anyone offer some insight whether this is possible or suggest a possible implementation?
No, the calculator app doesn't have a public schema that you can use
to invoke it

Playing system sound without importing your own
(11 answers)
Closed 9 years ago.
This is just a question that came off of the top of my head, but does anyone know if there are more sounds built into the system besides the (0x450) click sound? I would assume that there are others that can be put into apps since there are a lot more than just one built into the iPhone.
There is a list posted to AudioServices - iPhone Development Wiki. I've not yet figured out if using this in the following way is grounds for rejection:
AudioServicesPlaySystemSound(1103);
Don't forget to include:
#import <AudioToolbox/AudioToolbox.h>
Check all system sounds with: iOSSystemSoundsLibrary
