objective c - iOS moving cursor from keyboard extension -

we can update cursor position of uitextfield this.

[textfield setselectedrange:beginningrange]; 

is possible update cursor position keyboard extension? checking textdocumentproxy , inputview though.

simply set length of selection zero.

one possible implementation:

+ (void)setcursorintextfield:(uitextfield *)textfield atindex:(nsinteger)index {     uitextposition *start = [textfield positionfromposition:[textfield beginningofdocument] offset:index];     uitextposition *end = [textfield positionfromposition:start offset:0];     [textfield setselectedtextrange:[textfield textrangefromposition:start toposition:end]]; }
