NSDictionary keys must be unique.
You can reverse keys with objects
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:allMySizeObjects forKeys:allMyNameObjects];
سؤال
I do it like this.
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:allMyNameObjects forKeys:allMySizeObjects];
allMyNameObjects = {a,b,c,d}
allMySizeObjects = {1,2,1,3}
And is dictionary = {a:1,b:2,d:3}
"c" does not appear, because it has same size with "a".
allMySizeObjects objects has in NSNumber
Why it does not work with the same key? And how to make that work? Thank you all for your help.
