Can't set component width in picker view - ios

Question

Am trying to set the width of two components in a picker view. They are of equal width, and I want to make one wider. For this reason, I have used the
(CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component
method.
My problem is that after I have set the method, I only get one component back instead of two. I have checked to see if I have written the method wrong, but can't find anything wrong.
Any idea what's wrong?
Here is the code:
#import "BIDDependentComponentPickerViewController.h"
#implementation BIDDependentComponentPickerViewController
#synthesize picker;
#synthesize stateZips;
#synthesize states;
#synthesize zips;
- (IBAction)buttonPressed:(id)sender
{
NSInteger stateRow = [picker selectedRowInComponent:kStateComponent];
NSInteger zipRow = [picker selectedRowInComponent:kZipComponent];
NSString *state = [self.states objectAtIndex:stateRow];
NSString *zip = [self.zips objectAtIndex:zipRow];
NSString *title= [[NSString alloc] initWithFormat:#"You selected zip code %#.", zip];
NSString *message = [[NSString alloc] initWithFormat:#"#% is in #%", zip, state];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)didReceiveMemoryWarning
{
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
#pragma mark - View lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSBundle *bundle = [NSBundle mainBundle];
NSURL *plistURL = [bundle URLForResource:#"statedictionary" withExtension:#"plist"];
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfURL:plistURL];
self.stateZips = dictionary;
NSArray *components = [self.stateZips allKeys];
NSArray *sorted = [components sortedArrayUsingSelector:#selector(compare:)];
self.states = sorted;
NSString *selectedState = [self.states objectAtIndex:0];
NSArray *array = [stateZips objectForKey:selectedState];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
self.picker = nil;
self.stateZips = nil;
self.states = nil;
self.zips = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

if (component == kStateComponent)
{

NSArray *array = [stateZips objectForKey:selectedState];
self.zips = array;
[picker selectRow:0 inComponent:kZipComponent animated:YES];
[picker reloadComponent:kZipComponent];
}
}
- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component
{
if (component == kZipComponent) {
return 90;
return 200;
}
}
#end

Answer 1

The line:
return 200;
is never reached. It should be outside the IF statement like so:
if (component == kZipComponent) {
return 90.0;
}
return 200.0;
Otherwise, your method does not return a value for any component OTHER than kZipComponent (so the width of other components is 0).
