原因:出现的原因一般是运行时未给 self.window的 rootViewController的对象分配内存造成的，如下面类似例子         NSArray *item = [NSArray arrayWithObjects:nc1, nil]; _tabBar.tabBar.backgroundImage = [UIImage imageNamed:@"tabbar

"expected at the end of input"是编译器或解释器的错误提示，意思是在代码的结尾处缺少了某些内容。这通常是由于括号、引号、分号等符号未正确匹配或缺失导致的。解决此问题的方法是检查代码的结尾是否缺少某些符号，或者检查代码中是否有未正确匹配的符号。 举个例子，如果你在C++中编写以下代码： ```c++ #include <iostream> using namespace std; int main() { cout << "Hello, world!" << endl; return 0; } // 缺少一个右括号 ``` 编译器会提示错误信息："expected '}' at the end of input"，这意味着在代码的结尾处缺少一个右括号。
