Equivalent in Objective-c of AS3's getDefinitionByName?

Question

有没有办法可以通过使用String在objective-c中创建/创建一个类，就像我可以在AS3中使用getDefinitionByName一样？

Answer 1

Try:

id object = [[NSClassFromString(@"NameofClass") alloc] init];

from this thread:

Create objective-c class instance by name?

Answer 2

I think you're looking for NSClassFromString. It should be used as such (I borrowed this code from this answer ; the code is from Dave DeLong):

Class dictionaryClass = NSClassFromString(@"NSMutableDictionary");
id object = [[dictionaryClass alloc] init];
[object setObject:@"Foo" forKey:@"Bar"];
