将背景图像放在分组的UITableView后面

Question

I've a grouped UITableView which has been resized and rounded. I would like to place a view BEHIND this table.I've tried:

[self.tableView addSubview:backgroundView];
[self.tableView sendSubviewToBack:backgroundView];

but it didn't work. This is what I obtain:

I would like to have the background in place of the black space.

Any idea?

Answer 1

How about [self.tableView setBackgroundView:backgroundView]; ?

Answer 2

Bear with me I'm a beginner. I just ran into this problem and I found two solutions. In my case, I was using a UITableView object.

To begin, add the background image into your app's directory. I put mine in "Supporting Files"

You can add the image as a UIColor object:

    ...
    [resultsTable setBackGroundColor:setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"background.jpg"]]];
    ...

The problem with this method is that it will repeat your background image because it's treating it as a pattern.

The better way:

     // Create a string to store the path location of your image, otherwise you would have    to provide an exact path name
     NSString *backPath = [[NSBundle mainBundle] pathForResource:@"background"
     ofType:@"jpg"];

    // Create a UIImage Object to store the image.
     UIImage *bgImage = [[UIImage alloc ] initWithContentsOfFile:backPath];

     // Create a UIImageView which the TableView 
     UIImageView *bgView = [[UIImageView alloc]initWithImage:bgImage];

     // Set your TableView's background property, it takes a UIView Obj.
     [resultsTable setBackgroundView: bgView];
     .....
