Table view as an object in a view - how to initialize with an array of data?
My goal is to have something like a "sele开发者_StackOverflow中文版ct" option in a HTML form, but now in my app. After doing research it's probably best to do this with a table view. I though of the picker view, but the fixed height is too big.
With the interface builder I simply placed a table view on my subclass of UIViewController.
How do I fill the Table view with options? I've seen many tutorials, but those are all for having a UITableView as their own class and filling up the entire screen. In my application this is just a small piece of the entire form.
What a nightmare to create a relatively simple thing like a table view. It either crashes or I get a table view that covers my entire view and that is not filled with anything.
The variable countryTable is connected to the object in the interface builder.
Frustrated after a hard day of work. Anyone got the complete working code? That would be great. I already had a great look at apple's explenation AND various tutorials, but I can't figure it out.
I've tried multiple things, but this is my current code:
@interface myView: UIViewController
{
NSArray *countryArray;
IBOutlet UITableView * countryTable;
}
@property (nonatomic, retain) UITableView *countryTabel;
@end
and in my .m file
@implementation myView
@synthesize countryTable;
- (void)loadView
{
self.countryTable.dataSource = self;
}
- (void)viewDidLoad
{
NSArray *array = [[NSArray alloc] initWithObjects:@"test1", @"test2",
@"test3",nil];
self.countryTable = array;
[array release];
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void) dealloc
{
[countryTable release];
[super dealloc];
}

numberOfRowsInSection:(NSInteger)section
{
return [self.countryTable count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [countryTable objectAtIndex:row];
return cell;
}
@end
You are on the right track. If you were to use a UITableViewController subclass, you would obviously have a full screen table view by default. Going the route of using a UIViewController subclass with a UITableView as a subview in the UIViewController's view is the right way to go. A few things that you will need to address are:
1) In the UIViewControllers header file you will need to add <UITableViewDatasource, UITableViewDelegate>
as your view controller is responsible for fill implementing this functionally.
2) In viewDidLoad:
, set self.contryTable.delegate = self;
and self.countryTable.datasource = self;
The following protocol methods need to be implemented like so:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return countryArray.count;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [countryArray objectAtIndex:row];
return cell;
}
Hope this helps.
