libc++abi.dylib:以 NSException 类型的未捕获异常终止
这是代码:
func stream(aStream: NSStream, handleEvent eventCode: NSStreamEvent) {
switch(eventCode){
case NSStreamEvent.HasBytesAvailable:
var buffer = [UInt8](count: 4096, repeatedValue: 0)
if ( aStream == GlobalVariables.inputStream){
while (GlobalVariables.inputStream!.hasBytesAvailable){
let len = GlobalVariables.inputStream!.read(&buffer, maxLength: buffer.count)
if(len > 0){
let output = NSString(bytes: &buffer, length: buffer.count, encoding: NSUTF8StringEncoding)!.stringByTrimmingCharactersInSet(
NSCharacterSet.whitespaceAndNewlineCharacterSet())
if (output != ""){
/
/
var buf = UnsafeMutablePointer<CChar>(buffer)
var bufString: String = String.fromCString(buf)!
if ((delegate) != nil){
delegate!.dataReceived(bufString)
}
}
}
}
}
break
case NSStreamEvent.OpenCompleted:
break
default: break
}
}
最佳答案
显然你没有在正确的对象上调用你的segue。请确保您在正确的对象上调用 performSegueWithIdentifier: 函数。例如:
这是正确的:
[self performSegueWithIdentifier:@"backSegue" sender:self];
这是不正确的:
[self.navigationController performSegueWithIdentifier:@"backSegue" sender:self];
