标题[问题] xib切换问题
时间Wed Sep 25 11:25:00 2013
各位先进大家好,
小弟我是ios develop的初心者,
今日在测试一项功能xib切换的时候,发生了一个问题!
假设我有三个viewcontroller : testveiwcontroller,
test2viewcontroller,
testTabcontroller,
如今程式进入点为testviewcontroller(当中有一按钮切换至test2viewcontroller)
code:
switchxib_test2ViewController *v2=[[switchxib_test2ViewController alloc] initWithNibName:@"switchxib_test2ViewController" bundle:nil];
[self.view.superview addSubview:v2.view];
[self.view removeFromSuperview];
[v2 release];
当画面切换至test2viewcontroller时(当中有一按钮切换至testTabcontroller)
code:
switchxib_testTabController *v3=[[switchxib_testTabController alloc] initWithNibName:@"switchxib_testTabController" bundle:nil];
[self addChildViewController:v3];
[self.view addSubview:v3.view];
[v3 release];
当切换至testtabcontroller时,错误产生：
Thread 1:EXC_BAD_ACCESS(code=1, address=xxx
====================================================================
请问各位大大这样子的错误讯息是哪里地方出错了呢？
ps:若是单一切换,如testviewcontroller -> test2viewcontroller [OK]
testview2controller -> testTabcontroller [OK]
但是将这三个xib串起来就会产生错误！
麻烦各位提供点意见～谢谢

1F：推 appleway:你的作法完全错了。[v2 release]; v2就死了 09/25 16:01
2F：→ appleway:活下来的是v2的view 因为v2 的view有superview. 09/25 16:02
