[英]Changing tableView Cell Image on selection shows multple selected cell images
我有帶單元格圖像的tableView我想在選擇任何單元格時添加選擇圖像,它可以正常工作,但問題是首先選擇一行,然后選擇第一行,然后選擇了row2,然后選擇了row2和row1,應該只能是row2不能同時選擇。
- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
cell = [self.tableView cellForRowAtIndexPath:indexPath];
if (indexPath.row==0) {
cell.imageView.image=[UIImage imageNamed:@"Activity2.png"];
}
else if(indexPath.row==1){
cell.imageView.image=[UIImage imageNamed:@"Catalog2.png"];
}
else{
cell.imageView.image=[UIImage imageNamed:@"Library2.png"];
}
NSUInteger row = indexPath.row;
[self.appDelegate.splitViewController viewWillDisappear:YES];
NSMutableArray *viewControllerArray=[[NSMutableArray alloc] initWithArray: [[self.appDelegate.splitViewController.viewControllers objectAtIndex:1] viewControllers]];
[viewControllerArray removeLastObject];
if (row == 0) {
self.firstDetailViewController=[[[FirstDetailViewController alloc] init]autorelease];
[viewControllerArray addObject:self.firstDetailViewController];
self.appDelegate.splitViewController.delegate = self.firstDetailViewController;
}
if (row == 1) {
self.secondDetailViewController=[[[SecondDetailViewController alloc]init]autorelease];
[viewControllerArray addObject:self.secondDetailViewController];
self.appDelegate.splitViewController.delegate = self.secondDetailViewController;
}
if (row == 2) {
self.myLearningViewController=[[[MyLearningViewController alloc]init]autorelease];
[viewControllerArray addObject:self.myLearningViewController];
self.appDelegate.splitViewController.delegate = self.myLearningViewController;
}
}
如果您使用的是iOS 5.0或更高版本,那么如果設置得當,您可以呼吁allowMultipleSelection 。 將此設置為NO
。 否則,請使用–deselectRowAtIndexPath:animated:說來清除第一個選擇。 在-tableView:didSelectRowAtIndexPath:
實現中調用這些方法之一。
我認為,您可以像這樣在cellForRowAtIndexPath
設置單元格的背景視圖
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.backgroundColor = [UIColor clearColor];
UIImageView *bgView= [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
bgView.backgroundColor = [UIColor clearColor];
bgView.image = [UIImage imageNamed:@"cellBgImage.png"];
cell.backgroundView = bgView;
並且,在didSelectRowAtIndexPath
,使用它
[tableView deselectRowAtIndexPath:indexPath animated:YES];
請檢查是否有幫助。
