i am working on a view controller that contains two picker views (FromCur ,ToCur). those picker views are filled by an xml parser . althoughthe NSLog in the Title for row function is not giving me a null answer , the picker views displays a question mark. i have been stuck on this for hours , please help me to find the bug .
my code is the following :
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[super viewDidLoad];
// [super viewDidLoad];
currencies = [[NSMutableArray alloc] init];
NSString *url=@"http://192.168.83.1:8080/jeeRestApp-1.0/rest/devise";
NSXMLParser *parser;
parser=[[NSXMLParser alloc] initWithContentsOfURL:[NSURL URLWithString:url]];
parser.delegate=self;
if ([parser parse]==FALSE){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Erreur" message:@"erreur de connection!" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
[alert show];
}
self.FromCur=[[UIPickerView alloc]init];
self.ToCur=[[UIPickerView alloc]init];
self.FromCur.showsSelectionIndicator = YES;
self.FromCur.opaque = NO;
self.ToCur.dataSource=self;
self.ToCur.showsSelectionIndicator = YES;
self.ToCur.opaque = NO;
[self.view addSubview: _FromCur];
[self.view addSubview: _ToCur];
[self.FromCur reloadAllComponents];
[self.ToCur reloadAllComponents];
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)Cur{
self.FromCur=Cur;
self.ToCur=Cur;
NSLog(@"number of components ");
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
self.FromCur=pickerView;
self.ToCur=pickerView;
NSLog(@"number of rows in component");
return currencies.count;
}
-(NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
_FromCur=pickerView;
_ToCur=pickerView;
curr=[currencies objectAtIndex:row];
NSLog(@"le nom est : %@",curr.nom);
return curr.nom;
}
