Object name from String in Objective-C

Question

i want to set the name of an object like UIButton from a string.

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

My goal is:

UIButton *someString = [[UIButton buttonWithType:UIButtonTypeCustom]retain];

how can i solve this?

That doesn't make much sense... your first code sample isn't even valid Objective-C, and it is not really clear what your intention is. A UIButton is no string. Please be more verbose, explain your problem that you want to solve with this "setting name of an object". — DarkDust

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];
