Make the label in an iOS UISegmentedcontrol span 2 lines - ios

Question

In my app, I am using a UISegmentedcontrol. Because the label in each of the three segments spans two lines, I need to customize the UISegmentedcontrol. I want to do two things: (1) Increase the height of the UISegmentedcontrol, and (2) Make the text label span two lines
I found the solution to #1 here: iOS: change the height of UISegmentedcontrol and here Change Height of UISegmentedControl and here http://iphonedevsdk.com/forum/iphone-sdk-development/74275-change-height-of-segmented-control.html
I couldn't find out how to make the label inside the UISegmentedcontrol span two lines. Any help would be greatly appreciated!
Cheers,
Frank

try this...
create a Category for UISegmentedControl ,suppose UISegmentedControl+Multiline
in UISegmentedControl+Multiline.h
#import <UIKit/UIKit.h>
#interface UISegmentedControl (Multiline)
- (void)insertSegmentWithMultilineTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated;
#end
and in UISegmentedControl+Multiline.m
#import "UISegmentedControl+Multiline.h"
#interface UIView (LayerShot)
- (UIImage *)imageFromLayer;
#end
#implementation UIView (LayerShot)
- (UIImage *)imageFromLayer {
UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, 0);
[self.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
#end
#implementation UISegmentedControl (Multiline)
- (void)insertSegmentWithMultilineTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated {
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
[label setTextColor:[self tintColor]];
[label setBackgroundColor:[UIColor clearColor]];
[label setFont:[UIFont systemFontOfSize:13]];
[label setTextAlignment:NSTextAlignmentCenter];
[label setLineBreakMode:NSLineBreakByWordWrapping];
[label setNumberOfLines:0];
[label setText:title];
[label sizeToFit];
[self insertSegmentWithImage:[label imageFromLayer] atIndex:segment animated:animated];
}
#end
finally import UISegmentedControl+Multiline.h in your class and use as follows
UISegmentedControl * segmentControl = [[UISegmentedControl alloc]initWithFrame:CGRectMake(3, 66, 314, 30)];
[segmentControl insertSegmentWithMultilineTitle:#"First\nLine" atIndex:0 animated:YES];
[segmentControl insertSegmentWithMultilineTitle:#"Second\nLine" atIndex:1 animated:YES];
[segmentControl insertSegmentWithMultilineTitle:#"Third\nLine" atIndex:2 animated:YES];
[segmentControl setSelectedSegmentIndex:0];
[segmentControl addTarget:self action:#selector(segmentControlClicked:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:segmentControl];
