ios - Add a drop down suggestion below a UISearchbar and UITextfields -


in ios app, there 3 separate text entry fields. 1 in searchbar , 2 in uialertview(that has 2 entry fields). need give drop down menu below fields can give suggestions user. have data needed in array(all 3 fields need same array suggestion). how this? should programmatically create uitableview appear below textfields(with basic cell, containing 1 text field) ? if so, how can right frame? or else, other method should refer?

here simple example. here taking 1 uitextfield. when becomes first responder, showing drop down i.e., uitableview . when object selected table view drop down collapse.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
