As seen image below, I am trying to customize my picker. I have successfully added images on my picker but not affected all other pickers.I have put my code as well for reference. Thanks a lot in advance, happy thanksgiving.
- (void)loadView
{
picker1 = [[UIPickerView alloc] initWithFrame:CGRectMake(30, 200, 250, 250)];
picker1.delegate = self;
picker1.dataSource = self;
picker1.showsSelectionIndicator = YES;
picker2 = [[UIPickerView alloc] initWithFrame:CGRectMake(390, 200, 250, 250)];
picker2.delegate = self;
picker2.dataSource = self;
picker2.showsSelectionIndicator = YES;
picker3 = [[UIPickerView alloc] initWithFrame:CGRectMake(750, 200, 250, 250)];
picker3.delegate = self;
picker3.dataSource = self;
picker3.showsSelectionIndicator = YES;
self.view = [[UIView alloc] initWithFrame:CGRectZero];
[self.view addSubview:picker1];
[self.view addSubview:picker2];
[self.view addSubview:picker3];
UIImage *seven = [UIImage imageNamed:@"seven.png"];
UIImage *bar = [UIImage imageNamed:@"bar.png"];
for(int i=1; i<=4; i++)
{
UIImageView *sevenView = [[UIImageView alloc] initWithImage:seven];
UIImageView *barView = [[UIImageView alloc] initWithImage:bar];
NSArray *imageViewArray = [[NSArray alloc] initWithObjects:
sevenView,barView,nil];
NSString *fieldName = [[NSString alloc] initWithFormat:@"column%d",i];
[self setValue:imageViewArray forKey:fieldName];
}
}
-(UIView *)pickerView:(UIPickerView *)pickerView
viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view
{
NSString *arrayName = [[NSString alloc] initWithFormat:@"column%d",component+1];
NSArray *array = [self valueForKey:arrayName];
return [array objectAtIndex:row];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview
// Release anything that's not essential, such as cached data
}
- (void)dealloc {
}
#pragma mark UIPickerViewDelegate methods
- (NSString*)pickerView:(UIPickerView*)pv titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [NSString stringWithFormat:@"%d",row];
}
#pragma mark UIPickerViewDataSource methods
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView*)pv
{
return 4;
}
- (NSInteger)pickerView:(UIPickerView*)pv numberOfRowsInComponent:(NSInteger)component
