Body
copied!<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>
