Question

Is it possible to pass a block of code, for example:

int i = 0;
while (i < [array count]) {

//Code to pass in here
i++;
}

Reason being that i need to perform various actions on every item in an array at different times, it’d be nice to have 1 method and pass it a block of code to run.

Answer 1

Have you considered using blocks. It’s just an idea and not working or compilable code

typedef int (^block_t)();

-(void) methodName:(block_t) code_block
{  
   int i = 0;
   while (i < [array count]) {
   code_block() //Code to pass in here

   i++;
}

block_t youCode = ^{ NSLog("Just an example"); }
[self methodName:youCode];
