Ui Picker view error cant resolve - ios5

Question

Still trying to figure out the UI picker view, 2 days on it now and for some reason im just stuck on this. Any advice please on what im doing wrong. Ive got a yellow triangle saying "Incomplete implementation" and a red triangle saying "Use of undeclared identifier numberOfComponentsinPickerView"
.h
#import <UIKit/UIKit.h>
#interface pick3 : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate> {
UIPickerView *select;
NSArray *list;
}
#property (strong, nonatomic) IBOutlet UIPickerView *select;
#end
.m
#import "pick3.h"
#interface pick3 ()
#end
#implementation pick3
#synthesize select;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
{
list = [[NSArray alloc] initWithObjects:#"Employed", #"Student", #"Retired", #"Homemaker", #"Self-employed", #"Unemployed", #"Other", nil];
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
//One column
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
//set number of rows
return list.count;
}
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
//set item per row
return [list objectAtIndex:row];
}
}

It's just a typo on your viewDidLoad: method.
You have an extra '{' before your 'list' and and extra '}' at the end of the file. Just remove them and you'll be ok.
Try this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
list = [[NSArray alloc] initWithObjects:#"Employed", #"Student", #"Retired", #"Homemaker", #"Self-employed", #"Unemployed", #"Other", nil];
}
