问题
i have not long bin doing code, Xcode so I'm a little rubbish basically i have created a .xib and would like it to be in a storyboard but i really don't have a glue where to start because i have a xib window that has UITableView
and UIPickerView
in it and all the code is fine in the xib but do i need to add code in the storyboard .h / .m etc and is it possible if not how can i do some kind of drop down menu for my app. Heres the code in the xib
#import <UIKit/UIKit.h>
@interface myview : UIViewController <UITableViewDelegate, UITableViewDataSource, UIPickerViewDelegate, UIPickerViewDataSource>
@property (strong, nonatomic) IBOutlet UITableView* tableView;
@property (strong, nonatomic) IBOutlet UIPickerView* pickerView;
@property (strong, nonatomic) NSMutableArray* tableData;
@property (strong, nonatomic) NSMutableArray* pickerData;
@end
This is the .m but i will break it up
#import "myview.h"
@implementation myview
@synthesize tableView, pickerView, tableData, pickerData;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
this is the -(void)viewDidLoad];etc..
- (void)viewDidUnload
{
[super viewDidUnload];
tableView.delegate = self;
tableView.dataSource = self;
pickerView.delegate = self;
pickerView.dataSource = self;
tableData = [[NSMutableArray alloc] init]; // table starts empty
pickerData = [[NSMutableArray alloc] initWithObjects:@"1", @"2", @"3", @"4", @"5", nil]; // picker starts with values 1, 2, 3, 4, 5
[tableView reloadData];
[pickerView reloadAllComponents]; // Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
-(bool)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (NSInteger)numberOfSectionsInTableView:(UITableView*)tableView {
//The number of sections in UITableView
return 1;
}
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section {
// The number of rows in the UITableView
return [tableData count];
}
- (UITableViewCell*)tableView:(UITableView*)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"cell";
UITableViewCell *cell = [tableView1 dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [ [UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
cell.textLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Whatever happens when you select a table view row.
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
// The number of sections in the UIPickerView
return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
// The number of rows in the UIPickerView
return [pickerData count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
// The data for each row in the UIPickerView
return [pickerData objectAtIndex:row];
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
// whatever you want to happen when a row is selected.
// here I am assuming you want to remove from the picker and add to the table on selection
[tableData addObject:[pickerData objectAtIndex:row]];
[pickerData removeObjectAtIndex:row];
[tableView reloadData];
[self.pickerView reloadAllComponents];
}
@end
i hope all this has made sense and i will look forward to hear from you
thanks so much for your time :)

There is no drop down menu automatic conversion. The process is manual, and is described below:
- Cut and paste from the xib to the a new storyboard view controller (open up the xib, select all and select copy, then go to storyboard and paste it into a empty view controller).
- Add a fresh view controller subclass (.m and .h) to the project.
- Cut and paste the custom method from the old view controller subclass to the new view controller subclass. Be careful not to migrate the code that loads the xib.
- First associate the new custom view controller subclass with the view controller in storyboard.
- Hook up all the IBActions and IBOutlets and you should be good to go!
- Optionally, you can look for ways to use segues instead of IBActions.
