I am trying to create spelling app but i stuck. User going to listen some word and will try to write it. i am trying to insert underline seperately to every characters on UITextField. Every underline will give a hint to user that how many characters exist in a word. Problem is some letters like "i","l" are so close to each other and i cant put same size underline to every letters. I could change empty blank length between characters on UITextField with this
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:strText];
range:NSMakeRange(0,[strText length] )];
txtTexts.attributedText = attributedString;
This is caused by the new SF font. You can use monospaced font.
UIFont.monospacedDigitSystemFontOfSize(, weight: )
