Objective-C NSMutableArray Count Causes EXC_BAD_ACCESS
- by JoshEH
I've been stuck on this for days and each time I come back to it I keep making my code more and more confusing to myself, lol. Here's what I'm trying to do. I have table list of charges, I tap on one and brings up a model view with charge details. Now when the model is presented a object is created to fetch a XML list of users and parses it and returns a NSMutableArray via a custom delegate. I then have a button that presents a picker popover, when the popover view is called the user array is used in an initWithArray call to the popover view. I know the data in the array is right, but when [pickerUsers count] is called I get an EXC_BAD_ACCESS. I assume it's a memory/ownership issue but nothing seems to help. Any help would be appreciated.
Relevant code snippets:
Charge Popover (Charge details model view):
@interface ChargePopoverViewController .....
NSMutableArray *pickerUserList;
@property (nonatomic, retain) NSMutableArray *pickerUserList;
@implementation ChargePopoverViewController
@synthesize whoOwesPickerButton, pickerUserList;
- (void)viewDidLoad {
JEHWebAPIPickerUsers *fetcher = [[JEHWebAPIPickerUsers alloc] init];
fetcher.delegate = self;
[fetcher fetchUsers];
}
-(void) JEHWebAPIFetchedUsers:(NSMutableArray *)theData {
[pickerUserList release];
pickerUserList = theData;
}
- (void) pickWhoPaid: (id) sender {
UserPickerViewController* content = [[UserPickerViewController alloc] initWithArray:pickerUserList];
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:content];
[popover presentPopoverFromRect:whoPaidPickerButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
content.delegate = self;
}
User Picker View Controller
@interface UserPickerViewController .....
NSMutableArray *pickerUsers;
@property(nonatomic, retain) NSMutableArray *pickerUsers;
@implementation UserPickerViewController
@synthesize pickerUsers;
-(UserPickerViewController*) initWithArray:(NSMutableArray *)theUsers {
self = [super init];
if ( self ) {
self.pickerUsers = theUsers;
}
return self;
}
- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
// Dies Here EXC_BAD_ACCESS, but NSLog(@"The content of array is%@",pickerUsers); shows correct array data
return [pickerUsers count];
}
I can provide additional code if it might help. Thanks in advance.
