ibm-mobilefirst - 成功连接几分钟后，Worklight Native iOS 应用程序以 NSRangeException 终止

我正在使用 Worklight 6.0.0.1 + 9-26 iFix。
成功调用 Worklight Connect 几分钟后，我们的应用程序崩溃并出现此错误，看起来可能涉及 Worklight 的 JSON 解析问题:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '-[__NSCFConstantString substringWithRange:]: Range {2147483647, 1} out of bounds; string length 0'

libc++abi.dylib: terminating with uncaught exception of type NSException

我们正在像这样进行连接并获得成功响应:

MyConnectListener *connectListener = [[MyConnectListener alloc] init];
[[WLClient sharedInstance] wlConnectWithDelegate:connectListener];


MyConnectListener implements WLDelegate

MyConnectListener.m:
-(void)onSuccess:(WLResponse *)response
{
    NSLog(@"Connection Success: %@", response);
}

-(void)onFailure:(WLFailResponse *)response
{
    NSLog(@"Connection failure: %@", response);
}

知道如何解决这个问题吗？

最佳答案

这已被记录为缺陷，并将在 future 版本中修复。当前的解决方法是使用以下语法禁用心跳功能:

[[WLClient sharedInstance] setHeartBeatInterval:-1];
