从数组中获取特定对象

像这样试试

NSArray *tempArray = [yourArray objectAtIndex:index]; 
NSLog(@"Print Temp Array %@",tempArray);

使现代化

Use for replace value 
[_arrSection replaceObjectAtIndex:index withObject:@"Replace Value Set Here"];

完成打印值后,你会得到你想要的结果。希望你会成功。谢谢:)

可以使用NSArray的objectAtIndex属性。使用索引号从NSArray获取对象。

喜欢 NSArray*getArray=[_arrSection对象AtIndex:2];

试试这个。

NSMutableArray *sectionArray = [[NSMutableArray alloc]init];
[sectionArray addObject:[[NSArray alloc] initWithObjects:@(29077), nil]];
[sectionArray addObject:[[NSArray alloc] initWithObjects:@(32102.38),@(67419.6),@(25913.85),@(247547.66),@(52869.06), nil]];
[sectionArray addObject:[[NSArray alloc] initWithObjects:@(43173),@(197220.19),@(108825), nil]];
[sectionArray addObject:[[NSArray alloc] initWithObjects:@(199476.25),@(814590.87), nil]];

int sectionIndex = 2;
NSArray *rowArray = [sectionArray objectAtIndex:sectionIndex];//
NSLog(@"rowArray:%@",rowArray);

int rowIndex = 1;
NSNumber *value = [rowArray objectAtIndex:rowIndex];//rowIndex
NSLog(@"rowIndex value:%@",value);
