ios check if text is too big for uiTextfield

Question

This question is not about UITextView: It's about UITextField.

How do I check if my text would be too long for my UITextField? I need to dynamically change the Height of my UITextField so that it accepts multiple lines. Is this possible or must I use a UITextView for this? I prefer UITextField because of the convenience of a placeholder text.

Text can never be too long for a text field, because it scrolls sideways. — matt, Sep 26 '14 at 08:52

You can use

sizeWithFont:

of NSString to avaluate the length of a string.

UITextField is not able to show multiple lines. For solutions take a look at

Objective C: How to create a multi-line UITextField?

Hi just use small trick for this code sample below.

+ (CGFloat)expectedHeightWithData:(MECommentData *)data
{
    @autoreleasepool
    {
        NSString *comment = data.comment;

        UIFont *commentSizeFont = [UIFont fontWithName:@"Miso-Bold" size: 15.0];
        CGSize commentSize = [NSString sizeWithFont:commentSizeFont width:225 heitght:3000 text:comment];

        return ceilf(commentSize.height);
    }

}
