查看不顯示 「有時」 可可

Question

以我AppDelegate-> applicationWillFinishLaunching我裝載兩個視圖控制器與

NSViewController *v = [[MyCustomViewController alloc] initWithNibName:@"aNib" bundle:nil]; 

MyCustomViewController的initWithNibName：束：方法是自動生成的：

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
... 

我添加他們在自定義視圖中的視圖：[theMainView addSubview：[v view]]

我不明白爲什麼有時（像十次中的一次）視圖被加載但不顯示。

編輯：

MyCustomViewController1 *v = [[MyCustomViewController1 alloc] initWithNibName:@"aNib" bundle:nil]; 
[themainview addSubview:[v view]]; 

MyCustomViewController2 *v2 = [[MyCustomViewController2 alloc] initWithNibName:@"aNib2" bundle:nil]; 
[themainview addSubview:[v2 view]]; 

self.view1 = [[themainview subviews] objectAtIndex:0]; 
self.view2 = [[themainview subviews] objectAtIndex:1]; 

[view2 setHidden:YES]; 

廠景和視圖2是在AppDelegate中

Answer 1

您的問題合成可能是2種的NSView性質的依賴是在themainview的subviews陣列的具體指標的意見。你需要確定你正在設定正確的觀點。

試試這個：

MyCustomViewController1 *v = [[MyCustomViewController1 alloc] initWithNibName:@"aNib" bundle:nil]; 
[themainview addSubview:[v view]]; 

MyCustomViewController2 *v2 = [[MyCustomViewController2 alloc] initWithNibName:@"aNib2" bundle:nil]; 
[themainview addSubview:[v2 view]]; 

self.view1 = [v view]; 
self.view2 = [v2 view]; 

[view2 setHidden:YES];
