Question

In my code I am using JSONValue to grab an NSDictionary.

The dictionary looks like this:

{
   {ID = 0, NAME = "Patrick"},
   {ID = 1, NAME = "Ted"},
   {ID = 2, NAME = "John"},
   {ID = 3, NAME = "Allen"},
   {ID = 4, NAME = "David"}
}

I would like to return the name of the corresponding ID in the following delegate function:

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

What is the most efficient way to do that?

Answer 1

For example:

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    // Assuming that you have just one component
    return [jsonDict[row] objectForKey: @(row) ];
}
