Question

I’m not sure what’s going on here. For some reason NSString seems unwilling to load in the double value d.

Here’s my code:

-(NSString*)minuteFormat:(double) d{
    NSString* mystring;
    if(d >= 10){
        mystring = [NSString stringWithFormat:@"%d", d];
    }else{
        mystring = [NSString stringWithFormat:@"0%d",d];
    }
    return(mystring);


}

Regardless of the value of d, the only thing that’s getting returned is 0 or 00. (And I’m sure d is getting inputted correctly, as I’ve used breakpoints to check.)

Could someone tell me what’s going on?

%d is for integers. You probably want %f. See String Format Specifiers
