Insert element at NSMutableArray's end - ios

Question

I am loading an array from a web service and displaying them in picker and all works fine. My array contains random number of questions for every category of questions. Now what i want is that i wanna add one more entry "Your own question" at the end of array so that the last row of picker displays "Your own question". How can i do this
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
UILabel *retval = (id)view;
if (!retval) {
retval= [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, [pickerView rowSizeForComponent:component].width, [pickerView rowSizeForComponent:component].height)];
}
// retval.text = [idAndNameArray objectAtIndex:row];
if([pickerType isEqualToString:#"picker"])
{
retval.text = [idAndNameArray objectAtIndex:row];
}
else
{
retval.text = [quesArray objectAtIndex:row];
}
retval.font = [UIFont boldSystemFontOfSize:14];
retval.numberOfLines = 3;
return retval;
}
This code only displays number of rows(questions) fetched from the web service.
EDIT 1:
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView
{
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component
{
if([pickerType isEqualToString:#"picker"])
{
return [idAndNameArray count];
}
else
{
return [quesArray count];
}
}
EDIT 2:
Resolved by making another NSMutableArray with my custom object "Your own question" and then appending it with the array fetched from web service
NSMutableArray *customObj = [NSMutableArray arrayWithObject: #"test"];
[quesArray addObjectsFromArray:customObj];

Answer 1

In UIPickerViewDataSource's method called pickerView:numberOfRowsInComponent: return your array's count plus one value(return arr.count+1;), and in the method of UIPickerVIewDelegatethat you have implemented return your label with the text when the component is greater than arr.count-1 (if(row>(arr-1)){//return the label with 'Your own question'}). Good Luck!
EDIT:
- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component
{
if([pickerType isEqualToString:#"picker"])
{
return [idAndNameArray count];
}
else
{
return [quesArray count]+1;
}
}
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {
UILabel *retval = (id)view;
if (!retval) {
retval= [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, [pickerView rowSizeForComponent:component].width, [pickerView rowSizeForComponent:component].height)];
}
// retval.text = [idAndNameArray objectAtIndex:row];
if([pickerType isEqualToString:#"picker"])
{
retval.text = [idAndNameArray objectAtIndex:row];
}
else
{
if(row>quesArray.count-1){
retval.text = #"You own question";
}
else{
retval.text = [quesArray objectAtIndex:row];
}
}
retval.font = [UIFont boldSystemFontOfSize:14];
retval.numberOfLines = 3;
return retval;
}
