sizeWithFont：minFontSize：actualFontSize：forWidth：lineBreakMode：iOS7替代

问题描述

请帮我找一个弃用方法的替代方法......

Help me please to find an alternative for deprecated method...

CGSize size = [title sizeWithFont:buttonFont
                                  minFontSize:10
                               actualFontSize:nil
                                     forWidth:_view.bounds.size.width
                                lineBreakMode:NSLineBreakByClipping];

可以（boundingRectWithSize：options：attributes：context :)执行此操作吗？像这样...

Can (boundingRectWithSize:options:attributes:context:) do this? Something like this...

    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [UIFont systemFontOfSize:10], NSFontAttributeName,
                                nil];

    CGSize size = [title boundingRectWithSize:CGSizeMake(_view.bounds.size.width-kBorder*2, _view.bounds.size.height)
                                      options:NSLineBreakByClipping
                                   attributes:attributes
                                      context:nil].size;

我是对的吗？
期待您的建议：）

Am I right?Looking forward your advices :)

推荐答案

查看我之前的回答使用此代码：

Have a look to a previous answer I made here using this code :

- (CGSize)text:(NSString *)text sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size
{
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(7.0))
    {
        NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                          font, NSFontAttributeName,
                                          nil];

        CGRect frame = [text boundingRectWithSize:size
                                          options:(NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading)
                                       attributes:attributesDictionary
                                          context:nil];

        return frame.size;
    }
    else
    {
        return [text sizeWithFont:font constrainedToSize:size];
    }
}
