i use network.framewrok to create a tcp connection, but crashed on iOS15.1,here is some code:
- (void)connectToIP:(NSString *)ip
onPort:(uint16_t)port
completionHandler:(ConnectCallbackV2)callback
{
if (@available(iOS 12.0, *)) {
_callback = [callback copy];
nw_parameters_configure_protocol_block_t tlsConfig = NW_PARAMETERS_DISABLE_PROTOCOL;
nw_parameters_configure_protocol_block_t tcpConfig = ^(nw_protocol_options_t options) {
NW_PARAMETERS_DEFAULT_CONFIGURATION(options);
nw_tcp_options_set_connection_timeout(options, 5.0f);
nw_tcp_options_set_enable_keepalive(options, true);
};
if (!_socket) {
_socket = nw_connection_create(
nw_endpoint_create_host(ip.UTF8String, [NSString stringWithFormat:@"%d", port].UTF8String),
nw_parameters_create_secure_tcp(tlsConfig, tcpConfig));
}
nw_connection_set_queue(_socket, _delegateQueue);
nw_connection_set_state_changed_handler(self->_socket, ^(nw_connection_state_t state, nw_error_t _Nullable error) {
switch (state) {
case nw_connection_state_failed:
case nw_connection_state_cancelled: {
// some logic
break;
}
case nw_connection_state_ready: {
// some logic
break;
}
default: {
// some logic
break;
}
}
});
nw_connection_start(self->_socket);
}
}
