    }

    - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
    {

        if (component == 0) {
            return [RaporlarList count];
        }
        return [RaporlarList count];

    }

    #pragma mark Picker Delegate Methods
    - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
    {

        if (component == 0) {
        eObje =  [RaporlarList objectAtIndex:row];
        return  eObje.ProjeAdii;

我不知道我是否理解得很好，但那不是更好吗？

if (component == 0)
    {
        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje Adı : %@", [[RaporlarList objectAtIndex:row] ProjeAdii]];
        lblProjeAdi.text = [NSString stringWithFormat:@"%@", resultString];

    }
    else
    {
        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje No: %@", [[RaporlarList objectAtIndex:row] ProjeNoo]];
        lblProjeNo.text = resultString;

    }
