IOS开发之TableView替换默认的checkmark为自定义图像
直接上代码:
On cellForRowAtIndexPath: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height); button.frame = frame; [button setBackgroundImage:image forState:UIControlStateNormal]; [button addTarget:self action:@selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor clearColor]; cell.accessoryView = button;checkButtonTapped:event: Method: - (void)checkButtonTapped:(id)sender event:(id)event { NSSet *touches = [event allTouches]; UITouch *touch = [touches anyObject]; CGPoint currentTouchPosition = [touch locationInView:self.tableView]; NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition]; if (indexPath != nil) { [self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath]; } }accessoryButtonTappedForRowWithIndexPath: Method - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { NSMutableDictionary *item = [dataArray objectAtIndex:indexPath.row]; BOOL checked = [[item objectForKey:@"checked"] boolValue]; [item setObject:[NSNumber numberWithBool:!checked] forKey:@"checked"]; UITableViewCell *cell = [item objectForKey:@"cell"]; UIButton *button = (UIButton *)cell.accessoryView; UIImage *newImage = (checked) ? [UIImage imageNamed:@"unchecked.png"] : [UIImage imageNamed:@"checked.png"]; [button setBackgroundImage:newImage forState:UIControlStateNormal]; }
