Guys i am facing an issue while implementing delegate method for UIPickerview. Description of the problem is, i want to have 3 components in pickerview and each component having different number of rows. The code for this is as follows
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 3;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
NSInteger rows;
if (0 == component)
rows = 5;
else if (1 == component)
rows = 10;
else
rows = 15;
NSLog(@"Number of rows returned for component %d are rows %d",component, rows);
return rows;
}
Following this i am implementing "titleForRow" delegate method code for which is as follows:
#pragma -mark UIPIckerView Delegate Methods
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
//NSString *temp;
//temp = [[NSString alloc] initWithString:[self.pocModelData.arrayOfDistricts objectAtIndex:row]];
if (0 == component)
{
NSLog(@"String returned is %@ for row %d for component %d", [self.pocModelData.arrayOfDistricts objectAtIndex:row], row, component);
return [self.pocModelData.arrayOfDistricts objectAtIndex:row];
}
else if
(1 == component){
NSLog(@"String returned is %@ for row %d for component %d", [self.pocModelData.arrayOfDistricts objectAtIndex:row], row, component);
return [self.pocModelData.arrayOfDistricts objectAtIndex:row];
}else{
NSLog(@"String returned is %@ for row %d for component %d", [self.pocModelData.arrayOfDistricts objectAtIndex:row], row, component);
return [self.pocModelData.arrayOfDistricts objectAtIndex:row];
}
//return temp;
// return [self.pocModelData.arrayOfDistricts objectAtIndex:row];
}
This method on execution is returning only 3 rows for each component, as shown by following statements

I am not able to comprehend as to why its executing only 3 times for each component? I am populating the rows with set of data, so data source is common for all of them. What is the issue here, i am not able to grasp and m stuck for some time now? Any guidance is highly appreciated and thanks in advance.
