iOS根据生日返回星座:
+ (NSString *)calculateConstellationWithMonth:(NSInteger)month day:(NSInteger)day {
NSString *astroString = @"魔羯水瓶双鱼白羊金牛双子巨蟹狮子处女天秤天蝎射手魔羯";
NSString *astroFormat = @"102123444543";
NSString *result;
if (month <1 || month > 12 || day < 1 || day > 31) {
return @"日期格式错误";
}
if (month == 2 && day > 29) {
return @"日期格式错误";
} else if (month == 4 || month == 6 || month == 9 || month == 11) {
if (day > 30) {
return @"日期格式错误";
}
}
result = [NSString stringWithFormat:@"%@",[astroString substringWithRange:NSMakeRange(month * 2 - (day < [[astroFormat substringWithRange:NSMakeRange((month - 1), 1)] intValue] - (-19)) * 2, 2)]];
return [NSString stringWithFormat:@"%@座", result];
}
