Eu sou o Marcelo! marcelofabri.com @marcelofabri_

Quem?!
Quem?
Sobre o que é essa palestra?
Sobre o que NÃO é essa palestra?
None
None
None
Mas sério, sobre o que é essa palestra?
Fácil. Barreiras.
None
Chega de nhenhenhe.
Primeira barreira
Xcode só roda no Mac OSX
Beleza. Arranjei um Mac. E agora? #comofas
Objective-C
Objective-C + (void)sendAsynchronousRequest:(NSURLRequest *)request queue:(NSOperationQueue*) queue completionHandler:(void (^)(NSURLResponse*, NSData*, NSError*))
handler [NSURLConnection sendAsynchronousRequest:req queue:queue completionHandler:^(NSURLResponse *resp, NSData *data, NSError *err) { NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]); }];
Acha isso ruim? Vamos ver algumas melhorias
home.view.frame = self.view.frame; [[home view] setFrame:[[self view] frame]]; Para acessar
propriedades, usa-se dot notation. Métodos são chamados com colchetes. Dot Notation
NSDictionary *palestrante = [NSDictionary dictionaryWithObjectsAndKeys:@"Marcelo", @"nome", @"Palmeiras", @"time", nil]; NSString
*nome = [palestrante objectForKey:@"nome"]; NSArray *numeros = [NSArray arrayWithObjects:[NSNumber numberWithInt:1], [NSNumber numberWithInt:2], nil]; NSNumber *um = [numeros objectAtIndex:0]; NSDictionary *palestrante = @{@"nome": @"Marcelo", @"time": @"Palmeiras"}; NSString *nome = palestrante[@"nome"]; NSArray *numeros = @[@1, @2]; NSNumber *um = numeros[0]; Literals http://clang.llvm.org/docs/ObjectiveCLiterals.html
None
Mas e o gerenciamento de memória? Me falaram que não
tem Garbage Collector.
Não tem mesmo. É usado contagem de referências. http://en.wikipedia.org/wiki/Reference_counting
Vou ter que controlar isso na mão?
NÃO!
ARC http://clang.llvm.org/docs/AutomaticReferenceCounting.html
None
There’s a twist!
ARC não é magia •“Objetos” do CoreFoundation (C) devem ser
controlados na mão •Retain cycles
Xcode
Xcode •Ruim, mas já foi pior! •Modinha nova: plugins ✓ColorSense-for-Xcode
✓KSImageNamed-Xcode http://mneorr.github.io/Alcatraz/
None
Sabe o que seria massa? Se eu pudesse usar alguma
coisa igual o maven.
Existe algo assim! Chama CocoaPods http://www.raywenderlich.com/12139/introduction-to-cocoapods
DEMO https://github.com/marcelofabri/devcamp-demo
“Acabei meu app. Vamos colocar na AppStore e ganhar milhões.”
É importante testar em dispostivos reais.
E o que isso significa?
DOR.
None
None
WHY?
Code Sign
Code Sign TestFlight HockeyApp
Relembrando •Só com Mac OSX •Objective-C •ARC •Xcode •CocoaPods •Code
