即时解析json提要，并根据解析的值将im放置在表视图单元格中的星图像。我想要的是尽快放置星级评分图像文本标签得到完成星级评价图像变得灵活，没有固定的框架。下面是输出结果的代码和屏幕截图。如何在文本标签旁边放置星级评分图片

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

尝试这个代码，我已经解决了

可以使用下面的方法来计算串的宽度和高度 -

- sizeWithFont：
- sizeWithFont：forWidth：lineBreakMode：
- sizeWithFont： constrainedToSize：
- sizeWithFont：constrainedToSize：lineBreakMode：
- sizeWithFont：minFontSize：actualFontSize：forWidth：lineBr eakMode：

，或者你可以把你需要设置标签宽度宽度的基础上，在这里https://developer.apple.com/library/ios/#documentation/UIKit/Reference/NSString_UIKit_Additions/Reference/Reference.html

的文档，然后设置你的明星图像的帧。

一个例子 -

CGSize sizeTitle = [titleStr sizeWithFont:[UIFont boldSystemFontOfSize:16.0] 
                                      constrainedToSize:CGSizeMake(200, 40) 
                                          lineBreakMode:UILineBreakModeWordWrap]; 

float width = sizeTitle.width;

ü可以给我根据上面的代码中的小例子来放置images..will不胜感激 – kingston 2012-02-13 12:09:03

考虑更新条件如果（n <= 5）我应该删除CGRect starFrame – kingston 2012-02-13 12:21:29

可以添加两行以上的宽度添加图像.. ima noob – kingston 2012-02-13 12:21:58
