我想通過使用AsyncUdpSocket library通過UDP發送一些小數據。有很多關於TCP連接的文檔,但沒有關於UDP連接的文檔。如何使用AsyncUdpSocket在Objective C中發送UDP數據?
我寫了這個類發送5個字節到遠程主機,但它看起來沒有什麼是實際去電線。我正在使用wireshark監視網絡,但我看不到傳出數據包。委託方法「didSendDataWithTag」從未被稱爲:(
任何想法我忘了嗎?
#import "UDPController.h"
@implementation UDPController
- (id)init
{
self = [super init];
if (self) {
socket = [[AsyncUdpSocket alloc] initWithDelegate:self];
}
return self;
}
- (void) sendUDPTest {
NSLog(@"%s", __PRETTY_FUNCTION__);
NSString * string = @"R/103";
NSString * address = @"192.168.1.130";
UInt16 port = 21001;
NSData * data = [string dataUsingEncoding:NSUTF8StringEncoding];
[socket sendData:data toHost:address port:port withTimeout:-1 tag:1];
}
/**
* Called when the datagram with the given tag has been sent.
**/
- (void)onUdpSocket:(AsyncUdpSocket *)sock didSendDataWithTag:(long)tag {
NSLog(@"%s", __PRETTY_FUNCTION__);
}
- (void)dealloc
{
[socket release];
[super dealloc];
}
@end
歡呼
嘿,哥們,我有個退出AsyncUdpSocket來得及發送數據包之前,如果它放在一個應用
相同的代碼工作正常。同樣的問題,我只是不明白你的解釋。說「放入應用程序」是什麼意思? – 2012-01-10 14:14:06
