iOS Swift UITextfield 调整字体大小宽度

Question

How to adjust UITextfield font size when it is hold long character? I tried adjustsFontSizeToFitWidth. it is not working. any help will be appricated.thanks in advance

Answer 1

With a UITextField, text must fit on one line and cannot wrap.

You have two options:

Shrink the font to fit on one line:

self.TextFieldExample.adjustsFontSizeToFitWidth = YES; 
self.TextFieldExample.minimumFontSize = 10.0; //Optionally specify min size

Use UITextView to enable text wrapping:

Answer 2

Working Swift 4 Solution

Make sure you set adjustsFontSizeToFitWidth to true and then set your minimumFontSize . This will scale the text inside the UITextField to fit the width of your UITextField with a minimum font size equal to or greater than what you set minimumFontSize to. When the text is still too long to scale down to fit at the minimum font size it will truncate the rest.

textField.adjustsFontSizeToFitWidth = true
textField.minimumFontSize = 10

Answer 3

or you can go to the Main.storyboard file and click on the text field you want to work with and then go to the identity inspector and select the minimum font size that you want to have :) enjoy coding If you have issues with this method check the photo down below:

Answer 4

You have to set the width first

textField.frame = CGRect(0, 0, your width, your height)

And

textField.minimumFontSize = 0.5
