IOS反射

//类名的反射

NSStrin *str = @"Person";

Class class = NSClassFromString(str);

Person *person = [[class alloc] init];

//Class 变成字符串

NSString *name = NSStringFromClass([Person class]);

//方法的反射

NSString *method = @"test";

SEL selector = NSSelectorFromString(method);

[person performSelector:selector];

[person release];
