Ciao a tutti eccoci ritrovati con un nuovo tutorial per quanto riguarda le basi della programmazione Obj-c oggi vi spiegher\u00f2 la classe NSArray.<\/p>\n

Senza che perdiamo tempo col creare un nuovo progetto continuiamo il nostro vecchio progetto Link<\/a><\/p>\n

Ora nel file main scrivete questo codice:<\/p>\n

[code lang=”obj-c”]<\/p>\n

\/\/Dichiariamo \u00a0 \u00a0 Allochiamo \u00a0 \u00a0 Inizializiamo l’array con degli oggetti<\/p>\n

NSArray *array=[[NSArray alloc]initWithObjects:@&quot;Diego&quot;,@&quot;Fabio&quot;,@&quot;Giuseppe&quot;, nil];<\/p>\n

\/\/ciclo terminer\u00e0 quando l’indice dell’array punter\u00e0 a nil<\/p>\n

for (int i=0; i&lt;[array count]; i++) {<\/p>\n

\/\/ogni ciclo verr\u00e0 mostrato in output l’elemento iesimo dell’array<\/p>\n

NSLog(@&quot;%@&quot;,[array objectAtIndex:i ] );<\/p>\n

}<\/p>\n

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

Un modo alternativo di inizializzare un NSarray \u00e8 il seguente :<\/p>\n

[code lang=”obj-c”]<\/p>\n

\/\/la differenza tra questa dichiarazione e quella di sopra \u00e8 che questo array avr\u00e0 gli stessi elementi di quello precedente<\/p>\n

NSArray *array2=[[NSArray alloc]initWithArray:array];<\/p>\n

for (int i=0; i&lt;[array2 count]; i++) {<\/p>\n

\/\/ogni ciclo verr\u00e0 mostrato in output l’elemento iesimo dell’array<\/p>\n

NSLog(@&quot;%@&quot;,[array2 objectAtIndex:i ] );<\/p>\n

}<\/p>\n

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

Come potete notare tutto realmente molto semplice come esercizio vi consiglio di creare un metodo che operi su \u00a0questa classe<\/p>\n
