ios中的二维数组

Question

我想在ios中使用二维数组,例如我想为tableview数据源准备一个数组,

UITableViewCell array[sections][rows];

像这样的东西,在这里我也不能预先确定尺寸.

谢谢

Answer 1

NSMutableArray *dataArray = [[NSMutableArray alloc] initWithCapacity: 3];

[dataArray insertObject:[NSMutableArray arrayWithObjects:@"0",@"0",@"0",nil] atIndex:0];
[dataArray insertObject:[NSMutableArray arrayWithObjects:@"0",@"0",@"0",nil] atIndex:1];
[dataArray insertObject:[NSMutableArray arrayWithObjects:@"0",@"0",@"0",nil] atIndex:2];

这就是你从数组中选择值的方法

NSMutableArray *subArray = [dataArray objectAtIndex:2];
NSLog(@"data : %@",[subArray objectAtIndex:0]);
