In questo tutorial vi mostrer\u00f2 alcune semplici animazioni grazie all’ausilio della classe\u00a0CABasicAnimation.<\/p>\n

Per prima cosa importate all’interno del vostro progetto il framework\u00a0QuartzCore poi inserite 3 pulsanti e una \u00a0label<\/em><\/p>\n

infine nel file .m inserite questi codici :<\/p>\n

Pulsante 1:<\/p>\n

[code lang=”obj-c”]<\/p>\n

\/\/creo un istanza della classe Cbasic<\/p>\n

CABasicAnimation\u00a0*move\u00a0=\u00a0[CABasicAnimation\u00a0animationWithKeyPath:@"transform.translation.x"\u00a0];<\/p>\n

\/\/set il punto iniziale
\n[move\u00a0setFromValue:[NSNumber\u00a0numberWithFloat:0.0f]];<\/p>\n

\/\/punto finale
\n[move\u00a0setToValue:[NSNumber\u00a0numberWithFloat:100.0f]];<\/p>\n

\/\/la durata
\n[move\u00a0setDuration:1.0f];<\/p>\n

\/\/parte l’animazione dove element sta per il vostro oggetto (es label)
\n[[element\u00a0layer]\u00a0addAnimation:move\u00a0forKey:@"transform.translation.x"];<\/p>\n

[\/code]<\/p>\n

Pulsante due \u00a0crea una rotazione dell’oggetto<\/p>\n

[code lang=”obj-c”]<\/p>\n

CABasicAnimation *fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
\n[fullRotation setFromValue:[NSNumber numberWithFloat:0]];
\n[fullRotation setToValue:[NSNumber numberWithFloat:((360*M_PI)\/180)]];
\n[fullRotation setDuration:0.5f];<\/p>\n

[[element\u00a0layer]\u00a0addAnimation:fullRotation\u00a0forKey:@"transform.rotation"];<\/p>\n

[\/code]<\/p>\n

Pulsante tre
\n[code lang=”obj-c”]<\/p>\n

CATransition *animation = [CATransition animation];
\n animation.duration = 1.0;
\n animation.type = kCATransitionFade;
\n animation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
\n [myLabel.layer addAnimation:animation forKey:@"changeTextTransition"];
\n \/\/cambia il testo
\n myLabel.text = @"iProg.it";[\/code]<\/p>\n
