iOS Development Note TextView

1. Cannot scroll

self.scrollenabled = NO;

2. Normal font

[Uifont systemfontofsize:30.0f]

3. Bold font

[Uifont boldsystemfontofsize:30.0f]

4. Text Box offset

Self.textcontainerinset = Uiedgeinsetsmake (Textview_top_inset, Textview_left_inset, TEXTVIEW_BOTTOM_INSET,TEXTVIEW _right_inset);

5. Get Input status

[Self becomefirstresponder];

6. Is it possible to edit

[Self seteditable:yes];

7. Limit the input length

According to this idea, the text length to be generated = Original text length-select text length + Enter text length. Considering the deletion situation, my code is as follows:-(BOOL) TextView: (Uitextview *) TextView Shouldchangetextinrange: (nsrange) range Replacementtext: ( NSString *) text{    if ([Text isequaltostring:@ ""] && range.length > 0) {        //delete character must be safe        return yes;< c3/>}    else {        if (textview.text.length-range.length + text.length > Max_input_length) {            Uialertview * alert = [[Uialertview alloc] initwithtitle:@ "exceeds maximum input length" Message:nil delegate:self cancelbuttontitle:@ "OK" Otherbuttontitles:nil];            [Alert show];            return NO;        }        else {            return YES;}}    }

8. Cannot select

[Self setselectable:yes];
