基於int數的密鑰對象

Question

int number = 3; 

NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys: 
           @"Apple",[NSNumber numberWithInt:0], 
           @"Peach",[NSNumber numberWithInt:1], 
           @"Lemon",[NSNumber numberWithInt:2], 
           @"Pineapple",[NSNumber numberWithInt:3], 
           ........................, 
           nil]; 

NSString *numberToKey = [dict objectForKey:number]; 

如何在字符串中插入基於int數的字典值？

Answer 1

你把值到字典用同樣的方法：

NSString *numberToKey = [dict objectForKey:[NSNumber numberWithInt:number]];
