tableView 左滑 修改文字颜色和背景色

啥都不多说了，直接上代码。加上去就可以跑了

• (NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath {

  UIImage *(^imageWithView)(UIView *) = ^(UIView *view) {
  UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0);
  [view.layer renderInContext:UIGraphicsGetCurrentContext()];
  UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  return image;
  };

  UIColor *(^getColorWithLabelText)(NSString *, UIColor *, UIColor *) = ^(NSString *text, UIColor *textColor, UIColor *bgColor) {
  UILabel *actionLb = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
  actionLb.font = [UIFont boldSystemFontOfSize:14];
  actionLb.text = text;
  actionLb.textColor = textColor;
  actionLb.textAlignment = NSTextAlignmentCenter;
  actionLb.backgroundColor = bgColor;

    return [UIColor colorWithPatternImage:imageWithView(actionLb)];
  

  };

// 添加按钮
UITableViewRowAction *rowAction1 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDestructive title:@"  "handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
    NSLog(@"点击了");

}];
rowAction1.backgroundColor = getColorWithLabelText(@"row1", [UIColor whiteColor], [UIColor lightGrayColor]);

UITableViewRowAction *rowAction2 = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:@"  "handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {
    NSLog(@"点击了");
}];

transferRowAction.backgroundColor = getColorWithLabelText(@"row2", [UIColor blackColor], [UIColor yellowColor]);

return @[rowAction1, rowAction2];

}
