在cocos2d-iphone中随机实现方法？

Question

I have some "void" methods in my project using cocos2d-iphone and would like make them random. Unfortunately, I'v found only little information about genareting random numbers. Any help is appreciated!

Answer 1

 Try this

 .h

-(int) randomGenarete;

 .mm

-(int) randomGenarete
{

int random_number = arc4random() % 100;  // return random 0 to 99
return random_number;

}

Answer 2

If I understand correctly you want to call a random method, right?
Get your method signatures in an array:

NSArray* methods = @[@"myMethod1", @"myMethod2", @"myMethod3"];

Pick a method name:

NSString* method = methods[arc4random()%method.count];

Call it:

[self performSelector:NSSelectorFromString(method)];

It would be also wise to check that self can respond to that selector first.
