objective c - iOS Parse Query - Percentage Logging Different Numbers -

-

i'm returning 2 different queries parse...1 likecount , 1 dislikecount. when query each , set them equal respective labels come out correct. trying percentage of likes dividing likecount likecount+dislikecount.

the query run when button pressed , push segue initialized. logs correct numbers (usually first time). however, after first time query run , 1 or maybe both of numbers values don't update , outputs labels initial text.

@property (nonatomic, assign) float likecount; @property (nonatomic, assign) float dislikecount;   - (void)queryforuseractivity {     //create array check either user photo     nsarray *userphotos = @[self.firstuserphoto, self.seconduserphoto];      pfquery *queryforlikes = [pfquery querywithclassname:kddactivityclasskey];     [queryforlikes wherekey:kddactivitytypekey equalto:kddactivitytypelikekey];     [queryforlikes wherekey:kddactivityfirstuserphotokey containedin:userphotos];     [queryforlikes wherekey:kddactivityseconduserphotokey containedin:userphotos];     [queryforlikes countobjectsinbackgroundwithblock:^(int number, nserror *error) {         self.totallikeslabel.text = [nsstring stringwithformat:@"%i", number];     }];      pfquery *queryfordislikes = [pfquery querywithclassname:kddactivityclasskey];     [queryfordislikes wherekey:kddactivitytypekey equalto:kddactivitytypedislikekey];     [queryfordislikes wherekey:kddactivityfirstuserphotokey containedin:userphotos];     [queryfordislikes wherekey:kddactivityseconduserphotokey containedin:userphotos];     [queryfordislikes countobjectsinbackgroundwithblock:^(int number, nserror *error) {         self.totaldislikeslabel.text = [nsstring stringwithformat:@"%i", number];     }];      pfquery *queryforapprovalpercent = [pfquery orquerywithsubqueries:@[queryforlikes, queryfordislikes]];     [queryforapprovalpercent countobjectsinbackgroundwithblock:^(int number, nserror *error) {         if (!error) {             self.likecount = [self.totallikeslabel.text floatvalue];             self.dislikecount = [self.totaldislikeslabel.text floatvalue];             nslog(@"%f", self.likecount);             nslog(@"%f", self.dislikecount);             float approvalpercentage = (self.likecount / (self.likecount + self.dislikecount)) * 100.0;             self.approvalpercentagelabel.text = [nsstring stringwithformat:@"%2.0f%%", approvalpercentage];             if (approvalpercentage < 5) self.approvalpercentagelabel.textcolor = [uicolor redcolor];         }     }]; }

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
