Hello guys,
There's some issue with my UIPickerView controller. The data won't pop up in it. The 'Drum' by itself is visible but empty.
My code is:
- (void)viewDidLoad
{
[[self navigationController]setToolbarHidden:YES animated:YES];
[self setItemShow:theItem];
self.uiPickerViewData=[[[NSMutableArray alloc]initWithObjects:@"One",@"Two", nil]autorelease];
[super viewDidLoad];
}
And method which will work when button is getting tapped on
- (IBAction)setQuality:(id)sender
{
actionSheet=[[UIActionSheet alloc]initWithTitle:nil delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
[actionSheet setActionSheetStyle:UIActionSheetStyleDefault];
CGRect pickerFrame=CGRectMake(0, 44, 0, 0);
qualityPicker=[[UIPickerView alloc]initWithFrame:pickerFrame];
qualityPicker.dataSource=nil;
qualityPicker.delegate=self;
[actionSheet addSubview:qualityPicker];
[qualityPicker release];
UIToolbar *toolBar=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, actionSheet.bounds.size.width, 44)];
[toolBar setBarStyle:UIBarStyleDefault];
[toolBar sizeToFit];
UIBarButtonItem *spacer=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *setButton=[[UIBarButtonItem alloc]initWithTitle:@"Set" style:UIBarButtonSystemItemCancel target:self action:@selector(setQualityIntoDB)];
UIBarButtonItem *cancelButton=[[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonSystemItemCancel target:self action:@selector(cancel)];
[toolBar setItems:[NSArray arrayWithObjects:spacer,setButton,cancelButton, nil]animated:NO];
[spacer release];
[setButton release];
[cancelButton release];
[actionSheet addSubview:toolBar];
[toolBar release];
[actionSheet showInView:self.view];
[actionSheet setBounds:CGRectMake(0, 0, 320, 485)];
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 1;
}
- (NSInteger)numberOfRowsInComponent:(NSInteger)component
{
return [uiPickerViewData count];
}
-(NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [uiPickerViewData objectAtIndex:row];
}
-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
// Will be properly implemented later
DBAccess *access=[[DBAccess alloc]init];
[access closeDataBase];
[access release];
}
-(void)setQualityIntoDB
{
// int index;
DBAccess *access=[[DBAccess alloc]init];
[access closeDataBase];
[access release];
}
-(void)cancel
{
[actionSheet dismissWithClickedButtonIndex:0 animated:YES];
[actionSheet release];
}
The help is much appreciated. Thank you in advance
