NSString *buttonName = [[NSString alloc] initWithString:@"someString"];


My goal is:

You can’t – variable names are resolved by the compiler well before any Objective-C code is executed. What you can do is maintain a map of strings to objects like buttons etc. using NSMutableDictionary:

NSString *string = @"someString";
[buttonMap setObject: [UIButton buttonWithType:UIButtonTypeCustom] forKey: string];

//...time passes...

[[buttonMap objectForKey: @"someString"] setEnabled: YES];
