objective c - Populating ViewBased table from data in 6 different NSMutable arrays -

i have 6 different nsmutable arrays [(arr(a); arr(b); etc.] each of represents data 1 cell of row in table. array key representation. built in prior classes, passed current class , have same number of string objects (63) in each. table essential data representation of

questions:

1. must build nsdictionary 'keys' , 'objects'. how build thatdictionary. have tried various methods stepping through count loop no success. can find method inserting objects specific keys.

2. can load table directly various arrays without viewcontroller. have table , id's laid out have not been able add viewcontroller class - have 'files owner'. if easiest how can that.

3. if needed, how take elements of 6 arrays in order comma delimited string in array becomes input row of of table , therefore parsed table.

no code offer because attempts w/code have been unsuccessful.

need specific direction here.

must build nsdictionary 'keys' , 'objects'. how build thatdictionary. have tried various methods stepping through count loop no success. can find method inserting objects specific keys.

not required, advisable.

// assume 6 arrays array0, array1, ... // assume array0.count == array1.count == etc (int i=0; i<array0.count; ++i) {     nsdictionary *di = @{ @"ar0":array0[i], @"ar1":array1[i],... }; } 

but better idea nsobject subclass create meaningful users , has properties corresponding elements arrays (call meaningfulobject)....

// in datasource's interface definition @property(strong) nsmutablearray *myarrayofmeaningfulobjects;  self.myarrayofmeaningfulobjects = [@[] mutablecopy]; // assume array0.count == array1.count == etc (int i=0; i<array0.count; ++i) {     meaningfulobject *mi = [meaningfulobject meaningfulobjectwithattribute0:array0[i] attribute1:array1[i]... ];     [self.myarrayofmeaningfulobjects addobject:mi]; } 

can load table directly various arrays without viewcontroller. have table , id's laid out have not been able add viewcontroller class - have 'files owner'. if easiest how can that.

the table loads itself. job provide datasource, array of objects representing rows. people opt make view controller who's view contains table act datasource, table's datasource can object. 2 required parts of nstableviewdatasource protocol (1) numberofrowsintableview: this:

return self.myarrayofmeaningfulobjects.count; 

and (2) tableview:viewfortablecolumn:row: this:

meaningfulobject *mrow = self.myarrayofmeaningfulobjects[indexpath.row]; // configure tableview cell using mrow's attributes cell.textlabel.text = mrow.attribute0; 

if needed, how take elements of 6 arrays in order comma delimited string in array becomes input row of of table , therefore parsed table.

don't understand one, answer implicit in foregoing

edit, upon review of code, seems me you've got it. code has declared array basis of datasource, this:

@property(strong) nsmutablearray *rptdata; 

good, consequential mistake made here:

nsdictionary *rptdata = @{@"scott":[tblyrscott objectatindex:b],@"ext":rext,@"year":ryear,@"type":rtype,@"price":rprice,@"description":rdescription}; 

that's dictionary looks if represents single row in table, named confusingly nsarray property. looks if dictionary built abandoned on iteration of loop, overwritten object next row. make work, objects representing rows must added datasource, this:

// renamed rptdata dictionary rowdictionary nsdictionary *rowdictionary = @{@"scott":[tblyrscott objectatindex:b],@"ext":rext,@"year":ryear,@"type":rtype,@"price":rprice,@"description":rdescription}; [self.rptdata addobject:rowdictionary];
