OC中的数组遍历方法

OC中的数组遍历方法

NSArray *array = @[@"one",@"two",@"three",@"four",];

//第一种for遍历
for (NSInteger i = 0; i<array.count; i++)
{
NSLog(@"objects: %@ ",array[i]);
}

//第二种 快速枚举遍历
for (NSString *object in array)
{
NSLog(@"object: %@",object);
}

//第三种 使用枚举器遍历
NSEnumerator *enumerator = [array objectEnumerator];
id object = [enumerator nextObject];

while (object)
{
NSLog(@"object: %@",object);
object = [enumerator nextObject];
}
