在设备&上进行调试时，临时iPhone SIGSEGV崩溃模拟器作品 [英] Ad Hoc iPhone SIGSEGV crash while Debug on device & simulator works
问题描述
我尝试登录后，应用立即崩溃，因此它可能不是看门狗内存问题
App crashes immediately after I attempt to login so it can’t a be a watchdog memory issue
原因:_mh_execute_header 尝试使用ASIHTTPRequest发出网络请求时，应用程序崩溃. 请求永不触碰服务器. ASIHTTPRequest:我使用-fno-objc-arc从ARC省略了ASIHTTPRequest.
Reason: _mh_execute_header App crashes upon attempting to make a network request using ASIHTTPRequest. Request never touches server. ASIHTTPRequest: I use -fno-objc-arc to omit ASIHTTPRequest from ARC.
我相信以下电话正在引起我的问题，因为当我发出请求时，我的电话甚至从未碰过服务器.任何帮助将不胜感激！
I believe that the following call is causing my problems since my call never even touches the server when I make a request. Any help would be greatly appreciated!
致电:
NSDictionary *response = [[NetworkManager sharedManager] loginWithName:name password:pwd];
方法:
- (NSDictionary *)loginWithName:(NSString *)name password:(NSString *)pwd
{
NSURL *url = [NSURL URLWithString:@"http://www.test.com/keys"];
NSArray *values = [NSArray arrayWithObjects:@"iphone", @"iphone@test.com", name, pwd, nil];
NSArray *keys = [NSArray arrayWithObjects:@"name", @"email", @"username", @"password", nil];
NSDictionary *response = [self startNetworkPOSTRequestWithUrl:url
postValues:values
forKeys:keys];
return response;
}

推荐答案
我发现了另一个奇怪的解决方法，正在解决我的一些问题:
I found another odd workaround that's solving some of my problems:
在Target > Build Settings > Apple LLVM compiler 4.0 - Code Generation > Optimization Level下，我将Ad Hoc Optimization更改为None-远离默认的Fastest, Smallest [-Os]，这使我可以创建有效的ipa.
Under Target > Build Settings > Apple LLVM compiler 4.0 - Code Generation > Optimization Level I changed Ad Hoc Optimization to None - away from the default Fastest, Smallest [-Os] and this allows me to create a working ipa.
尽管这样做确实提供了一种解决方法，但考虑到我不进行优化可能会导致其他后果，因此它并不理想.
While this does provide a workaround it's less than ideal considering there may be other consequences of me doing no optimization.
但是我确实认为这暗示了我的一些潜在问题与内存有关-任何人都可以对此提供任何见解吗?
But I do think this hints that some of my underlying problems are memory related - can anyone provide any insights into this?
