GCDAsyncSocket的问题

iOS:GCDAsyncSocket 的二次封装,粘包处理因为要做实时数据所以简单的了解了下CocoaAsyncSocket这个库,其中的GCDAsyncSocket就是这个TCP协议通信的，看了一些网上demo之后基于目前使用的自定义协议的版本做了简单分装。这是自定以的协议头，后面拼接了一个json包(目前改为了protobuf,因为这个确实比较好用,体积也小),后面的封装基于这个协议，可供大家做一个参考！！！！ #import ty 阅读详情

iPhone是客户端，接收到服务器指令后在

-(void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag

里面处理数据然后再返回给服务器。
但是app会100%崩溃，很奇怪。

代码如下：



#import "CommandClient.h"

#import <UIKit/UIKit.h>  



@implementation CommandClient

+ (CommandClient *)sharedInstance {

    static CommandClient *sharedInstance = nil;

    static dispatch_once_t once;

    dispatch_once(&once, ^{

        sharedInstance = [[self alloc] init];

    });

    return sharedInstance;

}

- (void)initialize {

    

    static dispatch_once_t once;

    dispatch_once(&once, ^{

        NSLog(@"Start Creating GCDAsyncSocket");

        FMUtils = objc_getClass("FMUtils");

        socketClient =[[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];

    });

}

- (BOOL)startServer {

    NSLog(@"Start startServer GCDAsyncSocket");



    NSError *error;

NSString *host = @"192.168.0.9";

uint16_t port = 8666;

BOOL ret = [socketClient connectToHost:host onPort:port error:&error];

if (!ret) {

    NSLog(@"socketClient Connection: %@", error);

}



return ret;

}



- (void)stopServer {

    NSLog(@"Start stopServer GCDAsyncSocket");

    [socketClient disconnect];

    

    

}





#pragma mark - GCDAsyncSocketDelegate

// 已连接

- (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{

    [socketClient readDataWithTimeout:-1 tag:0];

    

    NSLog(@"Connected: %@:%d", host, port);

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"State" message:@"Connection Server Success!" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

    [alert addButtonWithTitle:@"Yes"];

    [alert show];



    }

-(void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{

           NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];

        NSString* sName = [dict objectForKey:@"sName"];

        if ([sName isEqual:@"getSkey"]) {

            NSString* sid = [dict objectForKey:@"sid"];

            NSString* result = [FMUtils encrySkey:sid];

            NSData *requestData = [result dataUsingEncoding:NSUTF8StringEncoding];

            

            

            [sock writeData:requestData withTimeout:-1. tag:0];

            

            

            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"State" message:@"send Server Success!" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];  //这两句注释掉就会百分百崩溃

            [alert release]; //这两句注释掉就会百分百崩溃

            

        }

    

        [socketClient readDataWithTimeout:-1 tag:0];

    }

- (void)socket:(GCDAsyncSocket *)sock didWriteDataWithTag:(long)tag

{

    

}

@end

很奇怪不添加这两句就会崩溃



UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"State" message:@"send Server Success!" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

[alert release];
