在iOS11中：
在该系统下由于我们所需自定义的按钮视图UISwipeActionPullView是UITableView的子视图，所以我们可以在控制器中自定义UITableView子类中遍历它的subviews即可（以下方法是写在UITableView的代理方法- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath中的，该代理方法每次会在开始左滑按钮前调用）。代码如下：
/**自定义设置iOS11系统下的左滑删除按钮大小*/
//开始编辑左滑删除
- (void)tableView:(UITableView *)tableView willBeginEditingRowAtIndexPath:(NSIndexPath *)indexPath {
NSInteger section = indexPath.section;
if (@available(iOS 11.0, *)) {
for (UIView * subView in self.customTableView.subviews) {
if ([subView isKindOfClass:NSClassFromString(@"UISwipeActionPullView")]) {
subView.backgroundColor = [UIColor clearColor];//如果自定义只有一个按钮就要去掉按钮默认红色背景
//设置按钮frame
for (UIView * sonView in subView.subviews) {
if ([sonView isKindOfClass:NSClassFromString(@"UISwipeActionStandardButton")]) {
CGRect cRect = sonView.frame;
cRect.origin.y = sonView.frame.origin.y + 10;
cRect.size.height = sonView.frame.size.height - 20;
sonView.frame = cRect;
}
}
//自定义按钮的文字大小
if (subView.subviews.count == 1 && section == 0) {//表示有一个按钮
UIButton * deleteButton = subView.subviews[0];
deleteButton.titleLabel.font = [UIFont systemFontOfSize:20];
}
//自定义按钮的图片
if (subView.subviews.count == 1 && section == 1) {//表示有一个按钮
UIButton * deleteButton = subView.subviews[0];
[deleteButton setImage:[UIImage imageNamed:@"login_btn_message"] forState:UIControlStateNormal];;
}
//自定义按钮的文字图片
if (subView.subviews.count >= 2 && section == 0) {//表示有两个按钮
UIButton * deleteButton = subView.subviews[1];
UIButton * shareButton = subView.subviews[0];
[self setUpDeleteButton:deleteButton];
[self setUpShareButton:shareButton];
}
}
}
}
}
