Answer 1

主要是 [self.window makeKeyAndVisible]; 这个地方崩

Answer 2

snViewController *viewControl这个地儿你不报错么、不应该是snSecondViewController么

Answer 3

真是不好意思 那个地方是写错了 不过改成snSecondViewController还是会崩

Answer 4

@synthesize window = _windows;
为什么右边要写成windows
不过我跑了一下，没什么问题

Answer 5

真是不好意思 那个地方是写错了 不过改成snSecondViewController还是会崩你这个程序我之前试了一下没有问题、你崩了有什么错误提示么

Answer 6

没有错误提示 只是每次单步跑到 [self.window makeKeyAndVisible];的时候都会跳到main函数里

Answer 7

self.window.backgroundColor = [UIColor whiteColor]; 去了试一下

Answer 8

Answer 9

是不是 snSecondViewController拼写错误？
