各位先進大家好,
小弟我是ios develop的初心者,
今日在測試一項功能xib切換的時候,發生了一個問題!
假設我有三個viewcontroller : testveiwcontroller,
test2viewcontroller,
testTabcontroller,
如今程式進入點為testviewcontroller(當中有一按鈕切換至test2viewcontroller)
code:
switchxib_test2ViewController *v2=[[switchxib_test2ViewController alloc] initWithNibName:@"switchxib_test2ViewController" bundle:nil];
[self.view.superview addSubview:v2.view];
[self.view removeFromSuperview];
[v2 release];
當畫面切換至test2viewcontroller時(當中有一按鈕切換至testTabcontroller)
code:
switchxib_testTabController *v3=[[switchxib_testTabController alloc] initWithNibName:@"switchxib_testTabController" bundle:nil];
[self addChildViewController:v3];
[self.view addSubview:v3.view];
[v3 release];
當切換至testtabcontroller時,錯誤產生：
Thread 1:EXC_BAD_ACCESS(code=1, address=xxx
====================================================================
請問各位大大這樣子的錯誤訊息是哪裡地方出錯了呢？
ps:若是單一切換,如testviewcontroller -> test2viewcontroller [OK]
testview2controller -> testTabcontroller [OK]
但是將這三個xib串起來就會產生錯誤！
麻煩各位提供點意見～謝謝

1F：推 appleway:你的作法完全錯了。[v2 release]; v2就死了 09/25 16:01
2F：→ appleway:活下來的是v2的view 因為v2 的view有superview. 09/25 16:02
3F：→ appleway:Check apple's doc about manage child viewcontrollers 09/25 16:04
