Question

I have a table view & I have to display text fields in some cells. When user click on the text field, I want the picker view to be displayed with integer values from 0 to 99. once the user selects the item in picker view the same needs to be displayed on that particular text field. Any help would be sincerely appreciated.

Answer 1

   -(void) viewDidLoad
 {
arrayNo = [[NSMutableArray alloc] init];
[arrayNo addObject:@"1"];
[arrayNo addObject:@"2"];
[arrayNo addObject:@"3"];
// and so on....
  }

Add target of this line to ur textfield function

  UITextfield *entered2;
  //..... some codes
   [entered2 addTarget:self action:@selector(showPicker)forControlEvents:UIControlEventEditingDidBegin];
[myview addSubview:entered2];




  -(void) showPicker
  {
[entered2 resignFirstResponder];
    pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,240,220,0)];

pickerView.delegate = self;
pickerView.dataSource = self;
pickerView.showsSelectionIndicator = YES;    

[self.view addSubview:pickerView];  
[pickerView release]; 
 }

 - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component 
   {
    return [arrayNo count];
   }
  - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
 return 1;  
   }
   - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
   {
entered2.text=[arrayNo objectAtIndex:row];
[pickerView removeFromSuperview];
   }
    - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
   {
return [arrayNo objectAtIndex:row];
[pickerView removeFromSuperview];
   }
   - (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component {
int sectionWidth = 300;
return sectionWidth;
     }
