iphone – UISegmentedControl文本多行？

概述如何使UISegmentedControl中的其中一个按钮的文本跨多行？ 我这样做： >创建一个多线UILabel >用N行文本填写标签 >将标签转换成UIImage >将图像设置为片段内容 这在iOS 4，5，6上顺利 和iOS 7(只是删除文字阴影) MultiLineSegmentedControl – 头文件 //// MultiLineSegmentedControl.h//// 如何使UISegmentedControl中的其中一个按钮的文本跨多行？解决方法 我这样做：

这在iOS 4，5，6上顺利

和iOS 7(只是删除文字阴影)

像普通的UISegmentedControl一样使用它：

...MultilinesegmentedControl *segment = [[MultilinesegmentedControl alloc]     initWithItems:[NSArray arrayWithObjects:@"A",@"B",nil]];segment.segmentedControlStyle = UISegmentedControlStylebar;segment.frame = CGRectMake(0,200,segment.frame.size.height * 1.5);[segment setMultilineTitle:@"Title A\nSubTitle A" forSegmentAtIndex:0];[segment setMultilineTitle:@"Title B\nSubTitle B" forSegmentAtIndex:1];[self.vIEw addSubvIEw:segment];[segment release];...
