Change Background of an Empty Table View

[algor_angel]

Hi, I would like to change the background of an empty tableView to show a message/image to say something like "No elements in this view" or whatever text/image I like to show. How do I do that?

i prefer to add a UILabel on the center of the screen. No needed to change background.

check the number of the rows (or the count of the array that contain the info of the tableview cells) and then enable visible=YES; or NO; of your UILabel

Hello Dany_Dev

Can you tell me that should I display a message in empty table in numberOfRowsInSection method? I have done this in numberOfRowsInSection method:

if([array count]==0)
	{
		UILabel *message=[[UILabel alloc]initWithFrame:CGRectMake(20, 100, 115, 35)];
		message.text=@"Empty";
		[tableView addSubview:message];
		[message release];
		
	}

But there is no error and nowarning and no expected output either?

Thanks

add a NSLog....checking that array.count is really 0 and if tableView is not nil....

[ahsan123]

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
	if([array count]==0)
	{
		NSLog(@"%d",[array count]);
	}
}

yes....and so? when I said add a NSLog i mean also to check its input and the other things I said....

Thanks dany_dev

It workrd when I wrote [[NSMutable array]retain] and removing [[NSMutable arrayWithObjects:@"",nil]retain]

but my question is will it make difficulties when enter new data?
because I could not enter data from another view "it is not displaying".

If you could tell me I'll be really thankful but thanks anyways.

[dany_dev]

I don't understand your question.

I mean will enter new data in the array if I did this:

[[NSMutableArray array]retain]
