我正在開發一個Swift應用程序。我使用套接字作爲後臺連接。但是要知道，我得到這個錯誤，當我嘗試使用它：Swift/Objective-C背景任務
libsystem_kernel.dylib`__pthread_kill:
0x11329edd0 <+0>: movl $0x2000148, %eax ; imm = 0x2000148
0x11329edd5 <+5>: movq %rcx, %r10
0x11329edd8 <+8>: syscall -> 0x11329edda <+10>: jae 0x11329ede4 ; <+20>
0x11329eddc <+12>: movq %rax, %rdi
0x11329eddf <+15>: jmp 0x113297d6f ; cerror_nocancel
0x11329ede4 <+20>: retq
0x11329ede5 <+21>: nop
0x11329ede6 <+22>: nop
0x11329ede7 <+23>: nop
這也表明「主題：信號SIGABRT」
。這裏我所說的方法：
let x:ComObwareAlifstoPostConnection = ComObwareAlifstoPostConnection()
DispatchQueue.global(qos: .background).async {
x.connect()
let y = x.getPostsWith("username", with: "password", with: "15000000000000", with: "down", with: "0")
DispatchQueue.main.async {
}
}
這裏是我的Objective-C類（它是由J2Objc轉換的Java）
- (IOSObjectArray *)getPostsWithNSString:(NSString *)username
withNSString:(NSString *)password
withNSString:(NSString *)time
withNSString:(NSString *)direction
withNSString:(NSString *)minTime {
IOSObjectArray *returnArray = nil;
@try {
[self connect];
if (ComObwareAlifstoPostConnection_socket == nil) {
return nil;
}
JavaIoDataOutputStream *os = new_JavaIoDataOutputStream_initWithJavaIoOutputStream_([ComObwareAlifstoPostConnection_socket getOutputStream]);
[os writeUTFWithNSString:JreStrcat("C$$$$$$$$$$", '2', ComObwareAlifstoPostConnection_SPLITTED, username, ComObwareAlifstoPostConnection_SPLITTED, password, ComObwareAlifstoPostConnection_SPLITTED, time, ComObwareAlifstoPostConnection_SPLITTED, direction, ComObwareAlifstoPostConnection_SPLITTED, minTime)];
[os flush];
JavaIoObjectInputStream *in = new_JavaIoObjectInputStream_initWithJavaIoInputStream_([((JavaNetSocket *) nil_chk(ComObwareAlifstoPostConnection_socket)) getInputStream]);
while ((returnArray = (IOSObjectArray *) cast_check([in readObject], IOSClass_arrayType(ComObwareAlifstoPostPost_class_(), 1))) != nil) {
return returnArray;
}
}
@catch (JavaNetUnknownHostException *e) {
}
@catch (JavaIoIOException *e) {
if (!hastried_) {
hastried_ = true;
return [self getPostsWithNSString:username withNSString:password withNSString:time withNSString:direction withNSString:minTime];
}
[((JavaIoIOException *) nil_chk(e)) printStackTrace];
}
@catch (JavaLangClassNotFoundException *e) {
}
return nil;
}
那麼，哪裏可能是錯誤？用一些其他的方法，它的作品。
