How to set top-left alignment for UILabel for iOS application?

Question

I have added one label in my nib file, then its required to have top-left alignment for that lable. As I am providing text at runtime so its not sure that how much lines the

Answer 1

I was also having this problem but what I found was the the order in which you set the UILabel's properties and methods matters!

If you call [label sizeToFit] before label.font = [UIFont fontWithName:@"Helvetica" size:14]; then the text does not align to the top but if you swap them around then it does!

I also noticed that setting the text first makes a difference too.

Hope this helps.

Answer 3

For iOS 7 that's what i made and worked for me

@implementation UILabel (VerticalAlign)
- (void)alignTop
{
    CGSize boundingRectSize = CGSizeMake(self.frame.size.width, CGFLOAT_MAX);
    NSDictionary *attributes = @{NSFontAttributeName : self.font};
    CGRect labelSize = [self.text boundingRectWithSize:boundingRectSize options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading
                                              attributes:attributes
                                                 context:nil];
    int numberOfLines= ceil(labelSize.size.height / self.font.lineHeight);

    CGRect newFrame = self.frame;
    newFrame.size.height = numberOfLines * self.font.lineHeight;
    self.frame = newFrame;
}

- (void)alignBottom
{
    CGSize boundingRectSize = CGSizeMake(self.frame.size.width, CGFLOAT_MAX);
    NSDictionary *attributes = @{NSFontAttributeName : self.font};
    CGRect labelSize = [self.text boundingRectWithSize:boundingRectSize options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading
                                            attributes:attributes
                                               context:nil];
    int numberOfLines= ceil(labelSize.size.height / self.font.lineHeight);

    int numberOfNewLined = (self.frame.size.height/self.font.lineHeight) - numberOfLines;

    NSMutableString *newLines = [NSMutableString string];
    for(int i=0; i< numberOfNewLined; i++){
        [newLines appendString:@"\n"];
    }
    [newLines appendString:self.text];
    self.text = [newLines mutableCopy];
}

Rather than re-explaining, I will link to this rather extensive & highly rated question/answer:

Vertically align text to top within a UILabel

The short answer is no, Apple didn't make this easy, but it is possible by changing the frame size.

Answer 5

As you are using the interface builder, set the constraints for your label (be sure to set the height and width as well). Then in the Size Inspector, check the height for the label. There you will want it to read >= instead of =. Then in the implementation for that view controller, set the number of lines to 0 (can also be done in IB) and set the label [label sizeToFit]; and as your text gains length, the label will grow in height and keep your text in the upper left.

Answer 6

If what you need is non-editable text that by default starts at the top left corner you can simply use a Text View instead of a label and then set its state to non-editable, like this:

textview.isEditable = false

Way easier than messing with the labels...
