    <p>I have a little coding problem at the moment. I have a picker with 7 different options, currently for testing purposes I have a label that will display the chosen value of the picker. </p> <p>The problem that I am having is that my label is only displaying whole numbers, not displaying the entire decimal number, can someone please help me so that I can obtain the full value of the chosen item in the picker?</p> <p>Here is my code :</p> <pre><code>// returns the number of 'columns' to display. - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } // returns the # of rows in each component.. - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [tempList count]; } - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { return [tempList objectAtIndex:row]; } - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { CGFloat chosenValue; switch (row) { case 0: chosenValue = 0.0000373; break; case 1: chosenValue = 0.0000273; break; case 2: chosenValue = 0.0000233; break; case 3: chosenValue = 0.0000204; break; case 4: chosenValue = 0.0000179; break; case 5: chosenValue = 0.0000169; break; case 6: chosenValue = 0.0000142; break; default: chosenValue = 0; break; } NSNumberFormatter *formatter = [[NSNumberFormatter alloc]init]; formatter.numberStyle = NSNumberFormatterDecimalStyle; self.testLabel.text = [formatter stringFromNumber:@(chosenValue)]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
