Objective – c 创建二维数组

NSArray _sectionDataStr;
_sectionDataStr = [[NSArray alloc] initWithObjects:
 [NSArray arrayWithObjects:@"Item1", @"Item2", nil],
 [NSArray arrayWithObjects:@"Item1", @"Item2", @"Item3", nil],
 [NSArray arrayWithObjects:@"Item1", @"Item2", @"Item3", @"Item4", nil],
 [NSArray arrayWithObjects:@"Item1", @"Item2", @"Item3", @"Item4", @"Item5",nil],
 nil];

 

 

打印

NSArray * array;
array = [_sectionDataStr objectAtIndex:0];
NSString* str = [array objectAtIndex:0];
NSLog(@"%@",str);

或

NSLog(@<span class="string">"%@"</span>,[[_sectionDataStr objectAtIndex:0] objectAtIndex:0]);

输出结果是：

Item1
