我需要将 uiButton 添加到静态 uitableview 部分标题 - 我尝试了以下内容 -
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
// you can get the title you statically defined in the storyboard
NSString *sectionTitle = [self tableView:tableView titleForHeaderInSection:section];
CGRect frame = tableView.bounds;
// create and return a custom view
#define LABEL_PADDING 10.0f
HeaderLabelStyling *customLabel = [[HeaderLabelStyling alloc] initWithFrame:CGRectInset(frame, LABEL_PADDING, 0)] ;
UIButton *addButton = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width-60, 10, 50, 30)];
addButton.backgroundColor = [UIColor whiteColor];
addButton.titleLabel.textColor = [UIColor colorWithRed:240/255.0f green:118/255.0f blue:34/255.0f alpha:1.0f];
addButton.titleLabel.tintColor = [UIColor blackColor];
UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 100, 30)];
title.text = @"iawn";
customLabel.text = sectionTitle;
customLabel.backgroundColor= [UIColor colorWithRed:143.0f/255.0f green:137.0f/255.0f blue:135.0f/255.0f alpha:1.0f];
customLabel.textColor = [UIColor colorWithRed:255/255.0f green:255/255.0f blue:255/255.0f alpha:1.0f];
[customLabel addSubview:addButton];
[addButton addSubview:title];
[addButton addTarget:self action:@selector(receiverButtonClicked:) forControlEvents:UIControlEventTouchDown];
return customLabel;
}
-(void)receiverButtonClicked:(id)sender{
NSLog(@"button clicked");
}
上面添加了一个按钮 - 但对点击事件没有反应 - 谁能建议我如何让它工作?
最佳答案
UILabel
默认不处理触摸。
添加以下代码行:
customLabel.userInteractionsEnabled = YES;
为了仅显示第三部分的按钮,您应该添加以下条件:
if(section == 2){...}
所以你的 -tableView:viewForHeaderInSection:
应该如下所示:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection (NSInteger)section {
if(section != 2) return nil;
// you can get the title you statically defined in the storyboard
NSString *sectionTitle = [self tableView:tableView titleForHeaderInSection:section];
CGRect frame = tableView.bounds;
// create and return a custom view
#define LABEL_PADDING 10.0f
HeaderLabelStyling *customLabel = [[HeaderLabelStyling alloc] initWithFrame:CGRectInset(frame, LABEL_PADDING, 0)] ;
UIButton *addButton = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width-60, 10, 50, 30)];
addButton.backgroundColor = [UIColor whiteColor];
addButton.titleLabel.textColor = [UIColor colorWithRed:240/255.0f green:118/255.0f blue:34/255.0f alpha:1.0f];
addButton.titleLabel.tintColor = [UIColor blackColor];
UILabel *title = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 100, 30)];
title.text = @"iawn";
customLabel.text = sectionTitle;
customLabel.backgroundColor= [UIColor colorWithRed:143.0f/255.0f green:137.0f/255.0f blue:135.0f/255.0f alpha:1.0f];
customLabel.userInteractionsEnabled = YES;
customLabel.textColor = [UIColor colorWithRed:255/255.0f green:255/255.0f blue:255/255.0f alpha:1.0f];
[customLabel addSubview:addButton];
[addButton addSubview:title];
[addButton addTarget:self action:@selector(receiverButtonClicked:) forControlEvents:UIControlEventTouchDown];
return customLabel;
}
