Passing NSInteger variable to NSMutableDictionary or NSMutableArray (7 answers)

Closed 8 years ago.

I need to store both the NSRange object and NSInteger inside the NSMutableDictionary?

Can I do it?

If it is, Could you give me an example?

Answer 1

You can store the NSInteger as NSNumber object.

mutableDictionary[integerKey] = [NSNumber numberWithInteger:integer];

or even better

mutableDictionary[integerKey] = @(integer);

For NSRange, use NSValue object.

mutableDictionary[rangeKey] = [NSValue valueWithRange:range];

Answer 2

I have used NSString for both NSRange and NSInteger, to remove confusion use this:

NSInteger i = 6;
    NSRange range = NSMakeRange (25, 3);
    NSMutableDictionary *dic =[[NSMutableDictionary alloc] init];
    [dic setObject:NSStringFromRange(range) forKey:@"range"];
    [dic setObject:[NSString stringWithFormat:@"%d",i] forKey:@"integer"];
    //How to get it...
    NSRange range1 =  NSRangeFromString([dic objectForKey:@"range"]) ;
    NSInteger inte = [[dic objectForKey:@"integer"] integerValue];
