呈現的UIViewController模態顯示移到頂部

Question

我呈現了一個帶有presentModalViewController：animated的UIViewController。

    CMImportViewControlleriPhone *import = [[CMImportViewControlleriPhone alloc] initWithNibName:@"Import-iPhone" bundle:nil];
    [import setModalPresentationStyle:UIModalPresentationFormSheet];
    [import setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
    [self presentModalViewController:import animated:YES];
    [import release];

但是，頂部的條不可見，並且似乎向頂部移動（底部有一個空白空間）。

這是viewDidLoad，其中我在navigationItem上設置了Close按鈕

- (void)viewDidLoad
{
    [super viewDidLoad];

    closeButton = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(closeButtonPushed:)];
    [[self navigationItem] setRightBarButtonItem:closeButton];
    [closeButton release];
}

謝謝

Answer 1

如果您使用的是iPhone，請刪除

[import setModalPresentationStyle:UIModalPresentationFormSheet];

Answer 2

您應該添加一個導航欄，然后顯示modalView

CMImportViewControlleriPhone *obj = [[CMImportViewControlleriPhone alloc] initWithNibName:@"Import-iPhone" bundle:nil];
[obj setDelegate:self];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:obj];
[self presentModalViewController:navigationController animated:YES];
[obj release];
[navigationController release];

希望這可以幫助。 快樂的編碼:)

添加UIBarButtonItem時，NavigationController為nil，navigationBar也為nil。 因此，它不適用於navigationItem。

closeButton = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(closeButtonPushed:)];
[[self navigationItem] setRightBarButtonItem:closeButton];

您應該為導入對象添加一個NavigationController並顯示它。

CMImportViewControlleriPhone *import = [[CMImportViewControlleriPhone alloc] initWithNibName:@"Import-iPhone" bundle:nil];
[import setModalPresentationStyle:UIModalPresentationFormSheet];
[import setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:import];
[self presentModalViewController:import animated:YES];
[import release];
[nc release];
