Answer 1

let's do tried and checkout

//Your Number to Round (can be predefined or whatever you need it to be)
float numberToRound = 1.12345;
float min = ([ [[NSString alloc]initWithFormat:@"%.0f",numberToRound] floatValue]);
float max = min + 1;
float maxdif = max - numberToRound;
if (maxdif > .5) {
    numberToRound = min;
}else{
    numberToRound = max;
}
//numberToRound will now equal it's closest whole number (in this case, it's 1)
