How to resize text (font) according to UISegment UISegmentedControl?

Question

Is there a way to reduce the size of a font that can be placed in one segment UISegmentedControl?

Tried a lot of something like:

[[UILabel appearanceWhenContainedIn:[UISegmentedControl class], nil] adjustsFontSizeToFitWidth];

[[UILabel appearanceWhenContainedIn:[UISegmentedControl class], nil] setMinimumScaleFactor:0.5];

and

 NSArray *arr = segment.subviews;  // segment is UISegmentedControl object

for (int i = 0; i < arr.count; i++) {

    UIView *aSegment = [arr objectAtIndex:i];

    for (UILabel *label in aSegment.subviews) {

        if ([label isKindOfClass:[UILabel class]]) {

            UILabel *myLabel = (UILabel *)label;

            [myLabel setNumberOfLines:0];

            label.numberOfLines = 0;
            label.adjustsFontSizeToFitWidth = YES;
            label.minimumScaleFactor = 0.5;
        }



    }
}

you can specify the number of lines of the segment label, for example,

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

You can set the size of one segment according to the content, for example,

  segment.apportionsSegmentWidthsByContent = YES;

but each segment has a different size in this case.

I want to keep the same size of each segment and want to reduce the size of the font that can be placed in UISegmentLabel (label)from UISegmentedControlsomething like minimumscalefactoror minimumfontsizeor adjustsFontSizeToFitWidth. These properties do not work for tags if they are contained in UISegmentedControl.

If someone can help achieve this, he will be appreciated!

Thanks in advance!

, !!! numberOfLines,adjustsFontSizeToFitWidth,minimumScaleFactor TitleTextAttributes toghether. titleTextAttribute, minimumScaleFactor .

 //this will allow multiple lines in label contained by every segment in segmentedcontroller

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


UISegmentedControl *segment = [[UISegmentedControl alloc]initWithItems:option];
segment.frame = CGRectMake(20, 50, self.view.frame.size.width - 40, 50);
segment.tintColor = [UIColor grayColor];
segment.selectedSegmentIndex = 0;
segment.backgroundColor = [UIColor whiteColor];
segment.tag = segmentedControllerBaseTag;


[segment addTarget:self action:@selector(segmentChanged:) forControlEvents:UIControlEventValueChanged];

[segment setTitleTextAttributes:@{NSFontAttributeName :[UIFont fontWithName:@"HelveticaNeue" size:17.0], NSForegroundColorAttributeName : [UIColor darkGrayColor] } forState:UIControlStateNormal];
[segment setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue" size:17.0],NSForegroundColorAttributeName : [UIColor whiteColor]} forState:UIControlStateSelected];

textattribute, ,

// ********** if titletextattributes are not set then below method works ***********

   for(uint i=0;i<[segment subviews].count;i++)
   {
    for(UIView *view in [[[segment subviews] objectAtIndex:i] subviews])
    {
        if([view isKindOfClass:[UILabel class]])
        {

            [(UILabel*)view setNumberOfLines:0];
            [(UILabel*)view setAdjustsFontSizeToFitWidth:YES];
            [(UILabel*)view setMinimumScaleFactor:0.7];


        }
    }
}

,

 //*************** adjust single segment size as per content

 segment.apportionsSegmentWidthsByContent = YES;
