UISegmentedControl text with multiple lines?

Use UIAppearance to get things done. The below code snippet will work. Call this before creating your segment.

Objective-C

[[UILabel appearanceWhenContainedIn:[UISegmentedControl class], nil] setNumberOfLines:0];

Swift

UILabel.appearanceWhenContainedInInstancesOfClasses([UISegmentedControl.self]).numberOfLines = 0

I did it this way:

• create a multiline UILabel
• fill the label with N lines of text
• convert the label into an UIImage
• set the image as a segments content

This works smooth on iOS 4, 5, 6

and iOS 7 (just remove the text shadow)

Use it just like a normal UISegmentedControl:

...MultiLineSegmentedControl *segment = [[MultiLineSegmentedControl alloc]     initWithItems:[NSArray arrayWithObjects:@"A", @"B", nil]];segment.segmentedControlStyle = UISegmentedControlStyleBar;segment.frame = CGRectMake(0, 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];...

Swift 3+ syntax based on answer by @Saranya Sivanandham

UILabel.appearance(whenContainedInInstancesOf: [UISegmentedControl.self]).numberOfLines = 0
