I have NSMutableArray data as below.

(
        {
        Id = "-1";
        NameEn = Country;
    },
        {
        Id = 14;
        NameEn = Iran;
    },
        {
        Id = 11;
        NameEn = Jordan;
    },
        {
        Id = 5;
        NameEn = "United Arab Emirates";
    },
        {
        Id = 4;
        NameEn = "Suadi Arabia";
    },
        {
        Id = 3;
        NameEn = Kuwait;
    },
        {
        Id = 10;
        NameEn = Yemen;
    },
        {
        Id = 6;
        NameEn = Oman;
    },
        {
        Id = 12;
        NameEn = Syria;
    },
        {
        Id = 7;
        NameEn = Qatar;
    },
        {
        Id = 13;
        NameEn = Lebanon;
    },
        {
        Id = 1;
        NameEn = Egypt;
    },
        {
        Id = 8;
        NameEn = "Bahrain Kingdom";
    }
)

I want to find the location where Id=5.

Any idea how can I do?

I tried with below.

NSString *myCountry = [[NSUserDefaults standardUserDefaults] valueForKey:@"mCountryId"];
NSUInteger indexOfTheObject = [feedsCountry indexOfObject: myCountry];
NSLog(@"indexOfTheObject===%i==%@", indexOfTheObject, myCountry);

if (NSNotFound == indexOfTheObject) {
    NSLog(@"not found...");
}

But I get output as not found... for mCountryId as 5.

Use an NSDictionary instead, and key your entries by Id; e.g.:

NSMutableDictionary* dictionary = [NSMutableDictionary new];

[dictionary setObject:@"Egypt" forKey:@"1"];
// (etc...)

EDIT: If you already have an array and can not change that, use a for loop like this:

for(NSDictionary* entry in givenArray){

    NSString* key = [entry objectForKey:@"Id"];
    NSString* value = [entry objectForKey:@"NameEn"];

    [dictionary setObject:value forKey:key];
}
