嗨,我有下一个问题,为什么当我发送这样的数据
uint8_t buffer[11] = "I send this";
NSInteger nwritten = [outputStream write:buffer maxLength:sizeof(buffer)];
if (-1 == nwritten) {
NSLog(@"Error writing to stream %@: %@", outputStream, [outputStream streamError]);
}else{
NSLog(@"Wrote %i bytes to stream %@.", nwritten, outputStream);
}
在java套接字服务器的另一端
connection = new Socket(Constants.HOST, Constants.CHAT_LISTENER_PORT);
_in = new DataInputStream(connection.getInputStream());
String data = _in.readUTF();
但没有任何东西看起来好像没有发送任何东西.
我读了很多,我发现问题来自平台,因为java字节适用于big-endians和带小端的iOS,但我没有找到有关如何做到这一点的信息.
uint8_t buffer [11] ="我发送此信息"; 到big-Endians格式
请heellppp,谢谢.
对不起,我的英语非常好,但西班牙语中没有任何内容:/ thaks.
我的应用程序崩溃了dealloc,但有时只会崩溃.
我创建了一个用于缓存5个对象的数组.当用户点击左右对象时,会添加一个新对象,并删除最后一个对象.当我测试应用程序时,在点击右键或左键100-500次后,应用程序崩溃了.
应用程序在dealloc方法中崩溃,但所有对象都已正确分配和释放.
我的dealloc方法:
- (void)dealloc
{
[super dealloc];
[_sImageLane release];
[_sTipoLane release];
[_maRecomended release];
[_maProdcucts release]; // here crash in this line EXC_BAD_ACCESSE
}
出了什么问题？
我有下一段代码,一个iVar保留了这个属性,并在它的类dealloc方法中发布.iVar用于2种方法并不断更改值,但有时当我使用该值时已损坏.这是为什么？
