Getting index of an String value within an array of array - ios

Question

I have an unique scenario of getting index value of an element, where the structure is
Array - within Array - within Dictionary
(
{
STS = OPEN;
"STS_ICON" = "LIGHT_GREY";
},
"Headerquarter Planning"
),
(
{
STS = INPR;
"STS_ICON" = "LIGHT_BLUE";
},
"In Process"
),
(
{
STS = COMP;
"STS_ICON" = "LIGHT_GREEN";
},
Released
),
(
{
STS = CANC;
"STS_ICON" = "LIGHT_RED";
},
"ON HOLD - Call Transfer Delay"
)
)
iN THIS Case let's say i want index of #"ON HOLD - Call Transfer Delay" string.
I tried with like this..
NSUInteger index;
if([listOfStatus containsObject: list.statusType])
{
index = [listOfStatus indexOfObject: list.statusType];
}
where list.statusType is #"ON HOLD - Call Transfer Delay". But here i am getting "index" some weird value 15744929.

Try
- (NSInteger)findIndexOfStatus:(NSString *)status
{
NSString *filePath = [[NSBundle mainBundle]pathForResource:#"Status"
ofType:#"json"];
NSData *data = [[NSData alloc]initWithContentsOfFile:filePath];
NSArray *listOfStatus = [NSJSONSerialization JSONObjectWithData:data
options:0
error:nil];
NSPredicate *predicate = [NSPredicate predicateWithBlock:^BOOL(NSArray *evaluatedObject, NSDictionary *bindings) {
//NSDictionary *dict = evaluatedObject[0];
//return [dict[#"STS"] isEqualToString:status];
NSString *statusType = evaluatedObject[1];
return [statusType isEqualToString:status];
}];
return [listOfStatus indexOfObjectPassingTest:^BOOL(id obj, NSUInteger idx, BOOL *stop) {
return [predicate evaluateWithObject:obj];
}];
}
You can find the index by calling
NSInteger index = [self findIndexOfStatus:#"ON HOLD - Call Transfer Delay"];
I have also commented out an option to find out if you want to use the status code.
The Status.json file
