Objective-C模態視圖

Question

是否可以在同一個.xib中顯示來自UIView或UIWindow的模態視圖？

這裏是我的代碼：

@interface MyViewController : UIViewController <UIWebViewDelegate> { 
IBOutlet UIVIew *myView 
} 

@property (nonatomic, retain) UIView *myView; 

- (void)somefunction; 

我的功能：

- (void)somefunction { 
    //here i need to make my view1 gets presented by a modal view style. 
} 

Answer 1

您需要添加IBOutlets您的觀點。在您的MyViewController.h文件中：

... 
IBOutlet UIView *firstView; 
IBOutlet UIView *secondView; 
... 

然後使用Interface Builder（或Xcode 4）連接插座。之後，在您的實施文件中，您可以手動隱藏或顯示所需的視圖。

PresenterViewController.m：

- (void)ShowSecondView{ 

    //Initialize the view controller 
    MyViewController *modalView = [[MyViewController alloc] initWithNibNamed:@"MyViewController" bundle:nil]; 

    //Hide or show whatever view(s) you want 
    [modalView.firstView setHidden:YES]; 
    [modalView.secondView setHidden:NO]; 

    //Present the view controller modally 
    [self presentModalViewController:modalView animated:YES]; 

    //Don't forget memory management! 
    [modalView release]; 
} 

您可能需要調整該代碼一點點，但這是一般的想法。
