Multiline Text On UIsegment Control

问题

I have a UISegmentControl with default style (White). I want to add text on it. But the text that i want to put on it is a long text.

I have to show the text in 2 lines of a segment. But i dont have to raise the width of the segment Because of screen width limit & no of segments.

I had tried to put a label on segment control programmatically, but my label is not displayed. Although we can put a label on segment control using XIB. but due to dynamic nature of text & segment control, I have to draw the segment control programmatically & also put the text on it.

Guidance will be appreciated.

Hi friend segment controller already have the label as the subview, so this code is helpful to achieve the multiline text to segment control

for (id segment in [segmentedControl subviews]) 
{
    for (id label in [segment subviews]) 
    {
        if ([label isKindOfClass:[UILabel class]])
        {
            //hear u add any of delegate function to increase the height and other label functionality in this 
            [label setTextAlignment:UITextAlignmentCenter];
            [label setFont:[UIFont boldSystemFontOfSize:12]];
//to adjust the label size manually with respect to text use below code
  CGSize labelSize = CGSizeMake(100, 80);
  CGSize theStringSize = [label.text sizeWithFont:label.font constrainedToSize:labelSize];
  CGRect frame = label.frame;
  frame.size = theStringSize; 

        }
    }           
}

Have a Good day
