param1_varName andOtherParameter:(param2_type)param2_varName
{
// implementation
}
@end

17. Objective C Syntax 3/3
@implementation ClientsMapViewController
@synthesize titleBar, mapView;
#pragma mark -
#pragma mark Lifecycle
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
!
! UIImageView *background = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)] autorelease];
! background.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
! background.image = [UIImage imageNamed:@"dark_wood_tile"];
! [self.titleBar addSubview:background];
! // Sending the image to the back ensures that the text isn't shadowed by the image
! [self.titleBar sendSubviewToBack:background];
! UIFont *font = [UIFont fontWithName:@"Lobster 1.4" size:17];
! UILabel *header = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
! header.text = @"Clients in the center of Copenhagen";
! header.font = font;
! header.textAlignment = UITextAlignmentCenter;
! header.textColor = [UIColor whiteColor];

filer og kompileres til NIB - realt
en serialisering af objekter.
• Utroligt simpelt men stærkt.
onsdag den 7. september 2011
26. iOS Simulator
• Til hurtig afvikling af dine
programmer - men ikke devicet
da simulator og device ikke er
100% ens.
• Understøtter flere typer af SDKs
samt Retina display og iPad.
onsdag den 7. september 2011
27. Instruments
• Instruments er din ven!
• Bruges til at finde memory leaks,
og over releases (NSZombie)

performance, finde flaskehalse
eller afvikling af automation
scripts.

• Configure Profile
• Certificates
• Signering af App før den kan afvikles på et device
• Devices
• 100 devices
• AppID
• Bruges bla. til In App Purchases, Push Notification, Hardware
Accessory, Game Center & iCloud
onsdag den 7. september 2011
31. Provisioning Portal
• Download & Install
• Development Provisioning Profile indeholder:
• Development Certificates
• Unique Device Identifiers

• Beskrivelse af produktet samt keywords
• Kategori
• Screen Shots
• Tilgængelighed (lande)
onsdag den 7. september 2011
35. The new kid on the block
• AppCode fra Jetbrains
• Bygger på Jetbrains IntelliJ framework
• Refactoring kendt fra Jetbrains andre
produkter så som IntelliJ, PyCharm,
RubyMine etc.
• Integration med andre (D)VCS
• Plugin ecosystem
• Kræver at Xcode og SDK allerede er
installeret
