不能在TTPostController检索成员对象:PostController的方法不能在TTPostController检索成员对象:PostController的方法
我一直在努力弄清楚为什么我无法返回任何使用TTPostController当我的成员对象:PostController中方法发送HTTP请求。这是我正在使用的代码。
页眉:
@interface NewReplyViewController : TTPostController <TTPostControllerDelegate> {
NSString * _thread_id;
}
@property (nonatomic, assign) NSString * thread_id;
-(id)initWithThreadId:(NSString *)threadId;
@end
实现:
@synthesize thread_id = _thread_id;
-(id)initWithThreadId:(NSString *)threadId {
self = [super initWithNibName:nil bundle:nil];
if (self) {
self.delegate = self;
self.thread_id = threadId;
self.title = kPostReplyPhrase;
self.navigationItem.rightBarButtonItem.title = kPostPhrase;
}
return self;
}
- (void)postController:(TTPostController *)postController
didPostText:(NSString *)text
withResult:(id)result {
NSLog(@"postController:postController self.threadid = %@", self.thread_id);
}
当我到达的NSLog部分,它会尝试按下发送按钮后返回的对象的线程ID,应用程序崩溃没有太多的细节。堆栈跟踪显示我的_thread_id对象,但我无法弄清楚为什么我无法达到它。关于我可能做错什么的想法?
以下是关于崩溃和一些细节的堆栈跟踪:

这很好地工作!感谢您的解释,现在更有意义。 – Ken 2011-05-23 09:32:22
