iOS隐式转换'；int'；至'；UIColor*'；不允许使用ARC

我有一个pickerview，它从一个单独的AFPickerView文件获取信息。我得到一个错误“ARC不允许将'int'隐式转换为'UIColor*”。有什么简单的解决方法吗

以下是其影响的代码：

[visibleViews minusSet:recycledViews];

    // add missing pages
    for (int index = firstNeededViewIndex; index <= lastNeededViewIndex; index++) 
    {
        if (![self isDisplayingViewForIndex:index]) 
        {
            UILabel *label = (UILabel *)[self dequeueRecycledView];

            if (label == nil)
            {
                label = [[UILabel alloc] initWithFrame:CGRectMake(_rowIndent, 0, self.frame.size.width - _rowIndent, 39.0)];
                label.backgroundColor = [UIColor clearColor];
                label.font = self.rowFont;
                label.textColor = RGBACOLOR(0.0, 0.0, 0.0, 0.75);
            }

            [self configureView:label atIndex:index];
            [contentView addSubview:label];
            [visibleViews addObject:label];
        }
    }
}
