我试着这样做,就像我用UITextField
做的那样:
textView.selectedTextRange = textView.textRange(from: textView.beginningOfDocument, to: textView.endOfDocument)
我做错了什么?

在选择文本字段第一响应者之前,您应该这样做:
awk -F, '
BEGIN {
split("site,fdate,prcp,snow,tmp2m,dpt2m,wchill,wind10m",tags)
print "<table id=\"alert\">"
}
{
printf "<tr>"
for (i=1; i in tags; i++) {
printf "<td class=\"%s\">%s</td>", tags[i], $i
}
print "</tr>"
}
END { print "</table>"}
' /home/weather/csv
...或者,更好的是,只需致电textView.becomeFirstResponder()
textView.selectedTextRange = textView.textRange(from: textView.beginningOfDocument, to: textView.endOfDocument)
:
selectAll
