Objective C
Education
USD 0.99 · Designed for iPad. Not verified for macOS.
Rebuilt from the ground up: a modern code editor, 14 example programs, saved programs, iPad split view and Dark Mode.
Write and run real Objective-C code on your iPhone or iPad.
Type a program, tap Run, and it is compiled with GCC and the GNUstep Foundation framework on a secure server. The output appears in seconds. It's a great way to learn Objective-C, try out an idea, or practise for an interview or exam, wherever you are.
FEATURES
• Code editor with Objective-C syntax highlighting, line numbers, bracket matching, undo and redo
• Extra keys above the keyboard for [ ] { } ( ) @ ; # and other symbols
• Clear compiler errors and warnings. Tap one to jump straight to the line
• Give your program input to read with scanf or fgets
• Save, rename, duplicate and share your programs
• 14 example programs: classes, properties, strings, arrays, dictionaries, inheritance, protocols, categories, exceptions, memory management and more
• Editor and output side by side on iPad
• Dark Mode
WHAT YOU CAN USE
Foundation classes such as NSString, NSArray, NSDictionary, NSNumber and NSException, plus the C standard library. Memory is managed manually with retain, release and autorelease, as in classic Objective-C. UIKit and ARC are not available.
Your programs are stored on your device. Code is sent to the server only to compile and run it, and is not kept.
