setting UILabel width acording to the length of uilabel.text that will change randomly

I have a UILabel in my app and text in that UILabel is fetching from internet so text length will differ so i want to add background color to black for UILabel but i also want the width of the UILabel to change when there is small length text will fetch in it. here is my code.

cell.songtitl.text = [[rssData objectAtIndex:indexPath.row]title];

this is how i am setting text to uilabel inside cellForRowAtIndexPath. and here is my TableViewCell.h

@property (weak, nonatomic) IBOutlet UILabel *songtitl;

here is what i want to avoid by setting background color on short titles.

enter image description here

I'm using these codes all of my project. These are giving you height and width dynamically. Hope it helps

+ (CGFloat) calculateHeightForText:(NSString *)str forWidth:(CGFloat)width forFont:(UIFont *)font {
CGFloat result = 20.0f;
if (str) {
    CGSize textSize = { width, 20000.0f };
    CGSize size = [str sizeWithFont:font constrainedToSize:textSize lineBreakMode:NSLineBreakByWordWrapping];
    result = MAX(size.height, 20.0f);
}
return result;
}

+ (CGFloat) calculateWidthForText:(NSString *)str forHeight:(CGFloat)height forFont:(UIFont *)font {
CGFloat result = 20.0f;
if (str) {
    CGSize textSize = { 20000.0f, height };
    CGSize size = [str sizeWithFont:font constrainedToSize:textSize lineBreakMode:NSLineBreakByWordWrapping];
    result = MAX(size.width, 20.0f);
}
return result;
}

Use this code for set UILablewidth as per text length

NSString *text = @"this is fortesting" ;
UIFont *font = [UIFont systemFontOfSize:10];
CGSize size = [(text ? text : @"") sizeWithFont:font constrainedToSize:CGSizeMake(220, 9999) lineBreakMode:NSLineBreakByWordWrapping];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(46, 200, size.width, size.height)];
label.numberOfLines = 0;
label.textColor = [UIColor grayColor];
label.lineBreakMode = NSLineBreakByWordWrapping;
label.text = (text ? text : @"");
label.font = font;
label.backgroundColor = [UIColor redColor];
[self.view addSubview:label];

I hope this code useful for you.

UILabel has inherited methods

- sizeThatFits:
- sizeToFit

doing the job you want Try to make first just

[cell.songtitl sizeToFit];

after assigning the text
