Objective-C iOS parse string according to the definition

I want create an iOS app for my school. This App will show Week schledule and when I tap on Cell with Subject, it will show me detail info about subject...

My problem: Our teachers use shotcuts for their names, but I want show their full name... I created the file "ucitele.h" with definitions of their names, but I don't know, how to use it 😕.

This is how that file looks:

//
//  ucitele.h
//

#define Li @"RNDr. Dan---vá"
#define He @"Mgr. Ja---hl"
#define Sm @"Ing. Mich---rek"
#define Ks @"Mgr. Svat---á"

I get the shortcut of Teacher from previous view from "self.ucitel" and I maybe want compare the contents of the "self.ucitel" with definitions and set the "ucitelFull" string from the definitions? I don't know how to say it 😕.

when the content of the self.ucitel will be @"Sm", than I want parse "ucitelFull" as @"Ing. Mich---rek"

Answers in Objective-C only please

Okay, sounds like your trying to map a short identifier to a full name: 

-(NSString*)fullNameFromShortName:(NSString*)short {

    NSDictionary * names = @{@"Li" : @"RNDr. Dan---vá",
                             @"He" : @"Mgr. Ja---hl", ... };

    return [names objectForKey:short];
}

Use like:

self.ucitelFull = [self fullNameFromShortName:self.ucitel];

This is a dictionary that has the short name as a key and the full name as the value.

Some further suggestions:

  • try using lowercase keys and comparing lowercaseString's, incase the user doesn't enter the value with the correct case.
  • You can move the dictionary definition into a json file and read it from your bundle, to eliminate the hardcoding
