这是崩溃报告，不知道为什么。我使用 AFHTTPRequestOperation setCompletionBlockWithSuccess:failure: 拨打电话。在完成块中，我得到结果并将其传递给我的数据模型上的类别类以插入到核心数据表中。
以下是崩溃日志..

请给我一些关于崩溃日志的见解。我已经做了几个小时了。
这是我的代码..
MyClient* client = [MyClient sharedClient];
[client setParameterEncoding:AFJSONParameterEncoding];
NSMutableURLRequest* request = [client requestWithMethod:@"POST" path:@"/JoinRoom" parameters:data];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[client registerHTTPOperationClass:[AFHTTPRequestOperation class]];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// Print the response body in text
//NSString* responseText = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSError* error3;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseObject //1
options:0
error:&error3];
NSString* status = [json objectForKey:@"status"];
if ([status isEqualToString:kBTOK]){ // OK
NSDictionary* room = [json objectForKey:@"data"];
BTRooms* newRoom = [BTRooms createNewRoom:room withNode:@""];
}
else{
// Do something else
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// Do something else
}];
[[[MyClient sharedClient] operationQueue] addOperation:operation];
[BTRooms createNewRoom:room withNode:@""] 看起来像这样..
+ (BTRooms*) createNewRoom:(NSDictionary *)roomDic withNode: (NSString*) node{
NSString* roomId = [roomDic objectForKey:@"roomid"];
//more code here
}
当我使用 xCode 连接和调试时，它不会崩溃。当应用程序在后台运行一段时间并且我在设备中运行它时，它会随机崩溃。进行远程调用的是我的标签栏控制器视图控制器之一。
新更新：
弄清楚了！对不起，误导性的问题。与iOS无关。这是来自服务器端的错误（应用程序引擎问题）。我将在一个单独的问题中发布。
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSError* error3;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseObject //1
options:0
error:&error3];
NSString* status = [json objectForKey:@"status"];
if ([status isEqualToString:kBTOK]){ // OK
NSDictionary* room = [json objectForKey:@"data"];
// room is null here!!
}
