Leaving Interface Builder Behind
- 1. Leaving Behind
- 2. Hello. • Jake Behrens • iPhone/Mobile Developer • UI Designer
- 3. Hello. • Freelancer (as of last Friday!)
- 7. Moments • Choose, but choose wisely. • Do it for the experience.
- 8. 30,000 Ft.
- 11. Why? • Knowledge. • Code reuse. • Performance. • Custom = code. • Tidbits here and there...
- 12. A Story
- 15. Delegates
- 16. Delegates Outlets
- 17. Delegates Location Outlets
- 18. Time
- 19. Code Reuse
- 20.

- 50. myButton.frame = CGRectMake(20.0, 20.0, 280.0, 37.0);
- 51. Refactor... • When changing a method name. • IB doesnʼt fix your action.
- 52. Bug Report • Great opportunity to tell Apple.
- 53. “Premature optimization is the root of all evil.”
- 54. So now what?
- 57. Tutorials!
- 62. Resources • Remove .xib files.
- 63. main.m #import <UIKit/UIKit.h> int main(int argc, char *argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, nil); [pool release]; return retVal; }

- 69. Custom Xcode Templates
- 70. Why? • Set it up the way you want it. • Include libraries you use.
- 72. AppDelegate.h #import <UIKit/UIKit.h> @class ___PROJECTNAMEASIDENTIFIER___ViewController; @interface ___PROJECTNAMEASIDENTIFIER___AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; ___PROJECTNAMEASIDENTIFIER___ViewController *viewController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet ___PROJECTNAMEASIDENTIFIER___ViewController *viewController; @end
- 73. Points of Interest • Delete the build folder. • .xcodeproj
- 75. Path to Customs
- 77. Graphical Elements In Code
- 78. .h #import <UIKit/UIKit.h> @interface DemoViewController : UIViewController { ! UILabel *displayText; } @property (nonatomic, retain) UILabel *displayText; @end
- 79. .m #import "DemoViewController.h" @implementation DemoViewController @synthesize displayText; #pragma mark - #pragma mark Application lifecycle - (void)loadView { ! [super loadView]; ! ! displayText = [[UILabel alloc] init]; ! [displayText setFrame:CGRectMake(20.0, 20.0, 280.0, 30.0)]; ! [displayText setText:@"Hello 360iDev!"]; ! [displayText setFont:[UIFont fontWithName:@"Helvetica" size:14.0]]; ! [self.view addSubview:displayText]; }
- 80. .m - (void)dealloc { ! [displayText release]; [super dealloc]; }
- 81. Yay...
- 82. .m - (void)loadView { ! [super loadView]; ! ! displayText = [[UILabel alloc] init]; ! [displayText setFrame:CGRectMake(20.0, 20.0, 280.0, 30.0)]; ! [displayText setText:@"Hello 360iDev!"]; !

- 83. Yay...
- 84. UIButton...again.

- 85. RE:cap • Increased performance. • Organization. • Little things.
- 86. Tuts • Revert apps created for IB. • Create customized project templates. • Create graphical elements and objects in code.
