[英]How do I set the background (window) for a tableview to an image?
I have set the background colour of my UITableView to clear so that I can see the UIWindow. 我将UITableView的背景色设置为清除,以便可以看到UIWindow。 But I want to change the image presented (from background.png), depending on my selection.
但是我要更改显示的图像(来自background.png),具体取决于我的选择。 An example would be: If (selection = 'blue') then image = bluesky.png if (selection = 'green') then image = 'greengrass.png
一个例子是:如果(selection ='blue')则image = bluesky.png如果(selection ='green')则image ='greengrass.png
thx, wes 谢谢
您可以使用图像设置表格视图的背景颜色,而不是使背景清晰并在其后放置图像。
self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"greengrass.png"]];
Just change the background image based on the selection, assuming your controller is UITableViewController
or implements the UITableViewDelegate
protocol, do something like: 只需根据选择更改背景图像,并假设您的控制器是
UITableViewController
或实现了UITableViewDelegate
协议,请执行以下操作:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *imageName = @"default.png";
switch (indexPath.row) {
case ...: // fill correct imageName based on selection
}
self.myBackgroundImageView.image = [UIImage imageNamed:imageName];
}
Btw - this also assumes you have an IBOutlet or something for your background image. 顺便说一句-这也假设您有IBOutlet或背景图片。
