为什么我在 iOS 应用程序中收到 EXC_ARITHMETIC 错误？

我的应用程序崩溃并出现 EXC_ARITHMETIC 错误，我不知道为什么。这是发生错误的地方：

int main(int argc, char *argv[]) {

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil); //ERROR IS HERE
    [pool release];
    return retVal;
}

当我单击应用程序中的按钮时，就会发生错误，它在我的 ViewController.m 文件中连接如下：

- (IBAction)btnPressed:(UIButton *)sender {
    [self btnPressed];
}

从同一文件调用此代码：

- (void)btnPressed {
    NSString *strInfo = [[NSString alloc] initWithString:@"Test Info. \r\n"];
    NSData *dataInfo = [strInfo dataUsingEncoding:NSUTF8StringEncoding];
    [strInfo release];
    [socket writeData:dataInfo withTimeout:-1 tag:1];
}

应用程序加载时也会调用 btnPressed并且它不会产生错误。同样，如果我向 [self btnPressed]; 行添加一个断点，那么当我单击应用程序中的按钮时，它会工作，在断点处停止，当我单击“继续程序执行”时，它会工作而无需错误也是如此。

注意：我使用 CocoaAsyncSocket 与 Cocoa 应用程序进行通信。

My app is crashing and getting an EXC_ARITHMETIC error and I don't know why. Here is where the error is happening:

int main(int argc, char *argv[]) {

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil); //ERROR IS HERE
    [pool release];
    return retVal;
}

The error happens when I click a button in the app, it's hooked up in my ViewController.m file like this:

- (IBAction)btnPressed:(UIButton *)sender {
    [self btnPressed];
}

Which calls this code from the same file:

- (void)btnPressed {
    NSString *strInfo = [[NSString alloc] initWithString:@"Test Info. \r\n"];
    NSData *dataInfo = [strInfo dataUsingEncoding:NSUTF8StringEncoding];
    [strInfo release];
    [socket writeData:dataInfo withTimeout:-1 tag:1];
}

The btnPressed is also called when the app loads and it DOES NOT produce an error. As well if I add a breakpoint to the [self btnPressed]; line then when I click the button in the app it works, stops at the breakpoint and when I click 'continue program execution' it works without error as well.

Note: I'm using CocoaAsyncSocket to communicate with a Cocoa app.
