How to expand and collapse rows at particular level in UITableView? - ios

Question

Rows of Level 1 should expand and collapse. Suppose if Row 0 is open - that means its status is 1 - and next row's status is 0, if I click on next row whose status is 0, then the row whose status is 1 should get closed.
How can I do that?
Here is my code:
- (void)viewDidLoad {
[super viewDidLoad];
dictBtnStatus = [[NSMutableDictionary alloc] init];
arraylist = [[NSMutableArray alloc] init];
array5 = [[NSMutableArray alloc] init];
array1 = [[NSMutableArray alloc] init];
objects = #[#"Medical Services In Chicago", #"Medical Services On Campus", #"ABC", #"California"];
// objects = #[#"Medical Services In Chicago", #"Medical Services On Campus"];
arrObjectValueChicago = #[#"Ronald McDonald® Children's Hospital of Loyola", #"Burn Centers", #"Gottlieb Hospitals"];
arrObjectValueCampus = #[#"Cardinal Bernardin Cancer Center1", #"Center for Heart & Vascular Medicine2", #"ABC"];
for (int i = 0; i < [arrObjectValueCampus count]; i++) {
dictListCampus1 = [[NSDictionary alloc] initWithObjectsAndKeys:#"2", #"level",[arrObjectValueCampus objectAtIndex:i], #"name", nil];
[array5 addObject:dictListCampus1];
}
NSDictionary *dictListCampus = [[NSDictionary alloc] initWithObjectsAndKeys:#"Wellness Centers", #"name", #"1", #"level", array5, #"Objects", nil];
NSMutableArray *array6 = [[NSMutableArray alloc] initWithObjects:dictListCampus, nil];
array3 = [[NSMutableArray alloc] init ];
for (int i = 0; i < [arrObjectValueChicago count]; i++){
dictList3 = [[NSDictionary alloc]initWithObjectsAndKeys:#"2", #"level",[arrObjectValueChicago objectAtIndex:i], #"name", nil];
[array3 addObject:dictList3];
}
NSDictionary *dictList2 = [[NSDictionary alloc] initWithObjectsAndKeys:#"Hospitals", #"name", #"1", #"level", array3, #"Objects", nil];
NSMutableArray *array2 = [[NSMutableArray alloc] initWithObjects:dictList2, nil];
for (int i = 0; i < [objects count]; i++) {
if (i == 0) {
dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:[objects objectAtIndex:0], #"name", #"0", #"level", array2, #"Objects", nil];
[array1 addObject:dictionary];
} else if (i == 1) {
dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:[objects objectAtIndex:1], #"name", #"0", #"level", array6, #"Objects", nil];
[array1 addObject:dictionary];
} else if (i == 2) {

[array1 addObject:dictionary];
} else {
dictionary = [[NSDictionary alloc] initWithObjectsAndKeys:[objects objectAtIndex:3], #"name", #"0", #"level", array2, #"Objects", nil];
[array1 addObject:dictionary];
}
}
dictList = [[NSDictionary alloc] initWithObjectsAndKeys:array1, #"Objects", nil];
arrayOriginal = [dictList valueForKey:#"Objects"];
[arraylist addObjectsFromArray:arrayOriginal];
}
