Is it possible to restart a for loop to its first iteration?

fast-enumeration, for-loop, objective-c

Solution

Not with fast enumeration, no (with the exception of goto), however if you use the indexed-access approach, you could:

NSUInteger count = [array count];
for (NSUInteger i = 0; i < count; i++)
{
    bool someflag = false;
    id object = array[i];
    if (isgood(object)) 
    {
        someflag = true;
        //restart to first object in loop
        i = 0;
    }
    if(someflag)
    {
        doStuffWithObject(object);
    }
}

Problem

In Objective-C, is it possible to restart to the first iteration of a for loop? I don't want to do anything with my objects until I find a "good" object, at which point I want to go back and do stuff with every object up to that good object. So, ``` bool someflag = false; for (id object in array) { if(object is good) { someflag = true; //restart to first object in loop } if(someflag) { doStuffWithObject(object); } } ``` Or is there a different/better way to do what I'm trying to do? Obviously the easy way would be to just have two separate `for` loops -- so if I could get a second opinion telling me that's the best way, that's just what I'll shoot for. For some reason I have a feeling there's got to be a better way, though.
