再init对象时还能发送UDP包，到了调用的时候就没反应了。function跑起来没问题，但是asyncUdpSocket的对象就是不发送UDP包。 Stackoverflow上都没人搭理我。 https://groups.google.com/forum/ ... csocket/GMLVDjzinNQ CocoaAsyncSocket 的google Group也没人回复。 抓狂了！！！！ .h #import <Foundation/Foundation.h> #import "AsyncUdpSocket.h" @interface Engine : NSObject{ AsyncUdpSocket *asyncUdpSocket; } @property (atomic, strong) AsyncUdpSocket *asyncUdpSocket; - (id) init; - (BOOL) startSession; - (void) doSomething; @end .m #import "Engine.h" @implementation Engine - (id) init { [self doSomething]; //<-----<< It can send ip packet out self = [super init]; [self doSomething]; //<-----<< It can send ip packet out, with wrong bind source port if (self){ } return self; } - (BOOL) startSession{ [self doSomething]; //<-----<< It won't send any ip packet out [self oxox]; return YES; } - (void) oxox{ [self doSomething]; //<-----<< It won't send any ip packet out } - (void) doSomething{ NSError *socketError=nil; asyncUdpSocket = [[AsyncUdpSocket alloc] initWithDelegate:self]; if (![asyncUdpSocket bindToPort:7701 error:&socketError]){ NSLog(@"RASEngine: Bind to Port fail"); } [asyncUdpSocket enableBroadcast:NO error:&socketError]; uint8_t signalBytes[] = {0x07, 0x07, 0x01, 0x06, 0x12, 0x34, 0x56, 0x78}; NSData *signalData = [NSData dataWithBytes:signalBytes length:8]; [asyncUdpSocket sendData:signalData //<--------<< It is called every time, but doesn't send anything out. toHost  "192.168.16.18"port:9902 withTimeout:-1 tag:0]; } #pragma mark - #pragma mark AsyncUdpSocket Delegate for UDP - (void)onUdpSocket  AsyncUdpSocket *)sock didSendDataWithTaglong)tag{NSLog(@"UDP Engine: onUdpSocket:didSendDataWithTag:%ld", tag); } - (void)onUdpSocket AsyncUdpSocket *)sock didNotSendDataWithTaglong)tag dueToErrorNSError *)error{NSLog(@"UDP Engine: onUdpSocket:didNotSendDataWithTag:%ld", tag); } @end |
