SSYTokenField bug (infinite loop) if one token is larger than the available width #1
Description
I don't know if you have time to update this repository, but I found your SSYTokenField class very useful. I found a bug.. if you have a token which is larger than the availableWidth, the code simply tries to create a newline and postpone the insertion of the token in the nextline.. but this leads to an infinite loop...
I solved in this way
if (requiredWidth > availableWidth) {
nRows++ ;
if (nRows == 1) {
// This would only happen if the first token by itself was too wide
// to fit in a row, which would be very rare
height += (tokenHeight + 2 * interrowSpace) ;
}
else {
height += (tokenHeight + interrowSpace) ;
}
if (!nTokensInThisRow) {
//This happens if one tag is too long to be added in one row, so
//we want to add this tag "alone" in a row.. it will be truncated by the NSTokenField.
//We now increase the height of the field by two rows
height += (tokenHeight + interrowSpace); //counting another row for the too-long tag
//we now count a fake row with one tag
nRows++;
nTokensInThisRow = 1;
nTokensPlaced++;
}
startingToken = startingToken + nTokensInThisRow ;
nTokensInThisRow = 0 ;
}
else {
nTokensInThisRow++ ;
nTokensPlaced++ ;
}The code I added is the following:
if (!nTokensInThisRow) {
//This happens if one tag is too long to be added in one row, so
//we want to add this tag "alone" in a row.. it will be truncated by the NSTokenField.
//We now increase the height of the field by two rows
height += (tokenHeight + interrowSpace); //counting another row for the too-long tag
//we now count a fake row with one tag
nRows++;
nTokensInThisRow = 1;
nTokensPlaced++;
}
