I currently build an NSMutableArray
in Class A.m within the ViewDidLoad
Method.
- (void)viewDidLoad
{
[super viewDidLoad];
//Question Array Setup and Alloc
stratToolsDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:countButton,@"count",camerButton,@"camera",videoButton,@"video",textButton,@"text",probeButton,@"probe", nil];
stratTools = [[NSMutableArray alloc] initWithObjects:@"Tools",stratToolsDict, nil];
stratObjectsDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:stratTools,@"Strat1",stratTools,@"Strat2",stratTools,@"Strat3",stratTools,@"Strat4", nil];
stratObjects = [[NSMutableArray alloc]initWithObjects:@"Strategies:",stratObjectsDict,nil];
QuestionDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:stratObjects,@"Question 1?",stratObjects,@"Question 2?",stratObjects,@"Question 3?",stratObjects,@"Question 4?",stratObjects,@"Question 5?", nil];
//add strategys to questions
QuestionsList = [[NSMutableArray alloc]init];
for (int i = 0; i < 1; i++) {
[QuestionsList addObject:QuestionDict];
}
NSLog(@"Object: %@",QuestionsList);
At the end of this method you will see QuestionsList being initialized and now I need to send this Array
to Class B.
So I place its setters
and getters
using the @property
and @Synthesize
method.
Class A.h
@property (retain, nonatomic) NSMutableDictionary *stratToolsDict;
@property (retain, nonatomic) NSMutableArray *stratTools;
@property (retain, nonatomic) NSMutableArray *stratObjects;
@property (retain, nonatomic) NSMutableDictionary *QuestionDict;
@property (retain, nonatomic) NSMutableArray *QuestionsList;
Class A.m
@synthesize QuestionDict;
@synthesize stratToolsDict;
@synthesize stratObjects;
@synthesize stratTools;
@synthesize QuestionsList;
I use the property method because I am going to call this variable from Class B and want to be able to assign it to another NSMutableArray
.
I then add the @property
and @class
for Class A to Class B.h as well as declare the NSMutableArray
in the @interface.
#import "Class A.h"
@class Class A;
@interface Class B : UITableViewController<UITableViewDataSource, UITableViewDelegate>{
NSMutableArray *QuestionList;
Class A *arrayQuestions;
}
@property Class A *arrayQuestions;
Then I call NSMutableArray
from Class A in the Class B.m
-(id)initWithStyle:(UITableViewStyle)style
{
if ([super initWithStyle:style] != nil) {
//Make array
arrayQuestions = [[Class A alloc]init];
QuestionList = arrayQuestions.QuestionsList;
Right after this I Log the NSMutableArray
to view values and check that they are there and it returns NIL
.
//Log test
NSLog(@"QuestionList init method: %@",QuestionList);
Info about Class B-
Class B is a UIPopOverController
for Class A, Class B has one View which holds a UITableView
which I have to populate the results of Class A's NSMutableArray
.
Why is the NsMutableArray
coming back as NIL
?
Ultimately would like some help figuring it out as well, it seems to really have me confused.
Help is greatly appreciated!!
