objective-c数组的迭代遍历方法

NSMutableArray *array = [NSMutableArray arrayWithCapacity:10];
[array addObject:@"onject1"]; 
[array addObject:@"object2"]; 
[array addObject:@"onject3"];
[array addObject:@"object4"];
[array addObject:@"object5"]; 
NSEnumerator *enumerator = [array objectEnumerator]; 

id object; 
int indexOfObject = 0;
while (object = [enumerator nextObject]) 

{ 
    NSLog(@"数组中的第@d个对象为：%@", indexOfObject, object); 
    indexOfObject++;
}

enumerator : 计数者, 计数员，计数器。
