我想我会在这个问题上难倒所有人。
我有一个 iOS 项目，它有两种进入应用程序的方式（见图）。
- 打开屏幕---->登录（电子邮件/密码）视图----->主视图
- 打开屏幕 ----> 注册视图 -----> 创建配置文件 -----> 输入安全代码视图 -----> 主视图
#1 路径永远不会失败，并且该应用程序运行良好。
第二个（＃2）不是那么多！使用路径#2，一旦用户进入 MainView，我将“findClosest”称为完美运行的 restkit 调用。第二次调用“findClosest”时，它变成了蒸汽，这意味着成功和失败的块永远不会被调用。我已经运行了 charles 并且调用正在访问服务器并返回，但是从不调用成功或失败块？然后每次连续调用“findClosest”都会变成蒸汽。
如果我关闭应用程序并重新启动，用户会通过上面的路径 #1，并且应用程序可以完美运行（又名 findClosest）。
===这里是“findClosest”方法==================================
-(void)findClosestThingWithIn:(NSNumber *)distance
latitude:(NSNumber *)lat
longitude:(NSNumber *)lng
limitTo:(NSNumber *)limit
type:(NSString*)thingType
{
//Setting these in here if NOT passed in as we have locationManager in restengine
if(nil == lat || nil == lng) {
//TODO: uncomment this.
lat = [NSNumber numberWithDouble:self.locationManager.location.coordinate.latitude];
lng = [NSNumber numberWithDouble:self.locationManager.location.coordinate.longitude];
}
NSAssert(lat, @"Cannot find an Thing without a lat");
NSAssert(lng, @"Cannot find an Thing without a lng");
NSAssert(self.accessToken, "TOken cannot be nil");
NSAssert(self.api_key, "TOken cannot be nil");
if(nil == lat || nil == lng) {
return;
}
if(self.accessToken && self.api_key) {
//Delete all previous things as we always want a fresh list
// [self performSelectorOnMainThread:@selector(deleteAllObjectsWithEntityName:) withObject:@"Thing" waitUntilDone:NO];
//[self deleteAllObjectsWithEntityName:@"Thing"];
RKObjectManager *mgr = [RKObjectManager sharedManager];
[mgr getObject:nil
path:@"v3/things/closest.json"
parameters:@{
@"auth_token" : self.accessToken,
@"api_key" : self.api_key,
@"lat" : ObjectOrNull(lat),
@"lng" : ObjectOrNull(lng),
@"max_distance" : ObjectOrNull(distance),
@"limit" : ObjectOrNull(limit),
@"type" : thingType
}
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
RKLogInfo(@"Find closest Things complete refresh view...");
[[NSNotificationCenter defaultCenter] postNotificationName:kFoundClosestThingss object:[NSNumber numberWithUnsignedInteger:[mappingResult count]] ];
if([mappingResult count] <= 0) {
[UIAlertView alertViewWithTitle:@"No available drivers" message:@"All thingss are currently busy. Please try again later."];
}
}
failure:^(RKObjectRequestOperation *operation, NSError *error) {
RKLogError(@"Find closest Things failed with error: %@", error);
[UIAlertView alertViewWithTitle:@"unavailable" message:@"Error. x005"];
}];
DLog(@"");
}
DLog(@"");
}
==================================================== =======
我不确定问题是否是故事板的#2 路径和推送，因为这真的是唯一的代码差异？为了尝试解决这个问题，我将输入代码视图中的 segue 删除到 MainView，而是将它们发送回打开屏幕以使其采用 #1 所采用的路径，但是会发生同样的错误吗？
附加 Restkit 日志（您可以看到对 ...closest.json 的两次调用都成功），但从未调用成功块。

// 更新 ////// 所以我删除了 VERIFY ACCOUNT 和 MainView 之间的 segue。现在我有一个额外的按钮，因此一旦您在 VERIFY ACCOUNT 视图中提交代码，您就会看到显示“开始使用”的新按钮。单击它会展开转回 SIGN IN 视图。所以现在当这个动作被执行时 MainView 加载，但是 MainView 的 dealloc 被调用了？
想知道这整个问题是否是因为导航控制器问题？这是我的应用程序的完整介绍。
