出于某种原因，当我尝试输入UISearchDisplayController时，我的应用程序崩溃了。我使用了here所需的代码，但我似乎无法找到解决方案。
以下是代码：

_cloudItems = [[NSMutableArray alloc] initWithObjects:@"The quick brown fox jumped over the lazy dog", @"foo", @"bar", @"Cookies", @"1234567890", nil];
...some more code
@end

这对您也很有用：

我该如何解决这个问题？我希望我已经提供了足够的信息。任何帮助表示赞赏。提前谢谢。
更新
如果我在SearchViewController.m内填写NSArray，......
_cloud = [[NSMutableArray alloc] initWithObjects:@"The quick brown fox jumped over the lazy dog", @"foo", @"bar", @"Cookies", @"1234567890", nil];
......我得到了一个不同的错误：
-[__NSCFConstantString objectForKey:]: unrecognized selector sent to instance 0x1659d4
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString objectForKey:]: unrecognized selector sent to instance 0x1659d4'

答案 0 :(得分：0)
[_cloudItems release];
// Show buttons when side is swiped
[[NSArray arrayWithObjects:
[NSDictionary dictionaryWithObjectsAndKeys:@"Reply", @"title", @"reply.png", @"image", nil],
[NSDictionary dictionaryWithObjectsAndKeys:@"Retweet", @"title", @"retweet-outline-button-item.png", @"image", nil],
[NSDictionary dictionaryWithObjectsAndKeys:@"Favorite", @"title", @"star-hollow.png", @"image", nil],
[NSDictionary dictionaryWithObjectsAndKeys:@"Profile", @"title", @"person.png", @"image", nil],
[NSDictionary dictionaryWithObjectsAndKeys:@"Links", @"title", @"paperclip.png", @"image", nil],
[NSDictionary dictionaryWithObjectsAndKeys:@"Action", @"title", @"action.png", @"image", nil],
nil] retain];
似乎这是罪魁祸首。你为什么要在viewDidLoad上发布那个数组？它看起来应该是：
_cloudItems = [[NSArray alloc] initWithObjects:[<dictionaries go here>]];
不要将保留放在最后，alloc将保留它。
希望这有帮助。
