IOS based on birthday get Zodiac, constellation, age algorithm

According to the user's birthday, get the corresponding age, Constellation and Zodiac. Some projects may be used, posted to share.

Get the age, this is simple:

-(void) Getagewith: (nsdate*) birthday{    // calendar    Nscalendar *gregorian = [[Nscalendar alloc] Initwithcalendaridentifier:nscalendaridentifiergregorian];         = nscalendarunityear;         *components = [Gregorian components:unitflags fromdate:birthday todate:[nsdate  Date] Options:0] ;     = [NSString stringWithFormat:@ "%ld years old ", [Components year]+1];}

Get a constellation based on the day of the month:

//get the constellation algorithm-(NSString *) Getastrowithmonth: (Nsinteger) M Day: (Nsinteger) d{nsstring*astrostring =@"capricorn Aquarius double milt goat Taurus Gemini giant crab lion Virgin libra scorpio shooter Capricorn"; NSString*astroformat =@"102123444543"; NSString*result; if(m<1|| M> A|| d<1|| D> to){                return @"wrong date format!"; }        if(m==2&& d> in)            {                return @"wrong date format !"; }Else if(m==4|| m==6|| m==9|| m== One) {                if(d> -) {                        return @"Bad date format!!!"; }} result=[nsstring stringWithFormat:@"%@", [Astrostring Substringwithrange:nsmakerange (m*2-(d < [[Astroformat Substringwithrange:nsmakerange (M-1),1)] [Intvalue]-(- +))*2,2)]]; return[Result stringbyappendingstring:@"seat"]; }

Get the Zodiac According to the year:

-(NSString *) Getzodiacwithyear: (Nsinteger) y{if(Y <0) {        return @"Bad date format!!!"; } nsstring*zodiacstring =@"Mouse cow tiger rabbit dragon snake horse sheep monkey chicken Dog pig"; Nsrange Range= Nsmakerange ((y+9)% A-1,1); NSString* result =[zodiacstring Substringwithrange:range]; return[Result stringbyappendingstring:@"years"]; }
