Objective-C Sandbox

A haphazardly conducted class

Hello World

• Open Xcode
• You'll see templates - select single view
• Create new "Hello World" - check local git if you want versioning - select a folder and you will have created the project
• Uncheck storyboards, uncheck include unit tests, select universal
• 
• Check out the views button on top right hand corner
• Nav on left, editor in center, utility on right, debug at bottom
• 
• Uncheck Autolayout:

• Select some tiny box (3rd on bottom row), drag a label to the panel, click on top row 4th button to see the label editing options, type hello world, and then press run.

• Published a hello world screen in the simulator

Traces

inside viewcontroller.m

    NSLog(@"trace");
    NSDate *dateObj = [[NSDate alloc] init];
    NSLog(@"date is %@", dateObj);

Syntax looks like this: MyNotes is the class:

MyNotes *notesObj = [[MyNotes alloc] init];
// pass single argument
[notesObj createNewNoteWithTItle:@"First Note"];
// pass multiple arguments
[notesObj createNewNoteWithTItle:@"First Note" andDescription:@"I Love ObjectiveC"];
