Early Exit from Fast Enumerate Loop?

When using fast enumeration, is there a way to exit early, i.e. before going through every element in the array?

    for (element in myArray)
    {
        //is there a way to exit before running through every element in myArray?
    }

Better way to do is, use blocks

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id object, BOOL *stop) {
stop = YES // To break the loop }];

break; will exit any for, while, or do loop.

For example:

for (element in myArray)
{
     if (someExitCondition)
     {
         break; /* leave now */
     }
}
