Question

我正在尝试将模态视图控制器显示为UIPresentationFormSheet。视图出现，但我似乎无法调整大小。我的XIB有适当的高度和高度。宽度，但是当我这样称它时它似乎被覆盖了：

composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil];
composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:composeTweetController animated:TRUE];

有什么想法？我使用的是iPhone SDK 3.2 beta 4

Answer 1

您可以在呈现后调整模态视图的框架：

在iOS 5.1 - 7.1

中测试

MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease];
targetController.modalPresentationStyle = UIModalPresentationFormSheet;
targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;  //transition shouldn't matter
[self presentViewController:targetController animated:YES completion:nil];

if(floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1){
     targetController.view.superview.frame = CGRectInset(targetController.view.superview.frame, 100, 50);
}else{
     targetController.view.frame = CGRectInset(targetController.view.frame, 100, 50);
     targetController.view.superview.backgroundColor = [UIColor clearColor];
}

Answer 2

这是一种适用于 iOS7 以及iOS5和iOS6的方法:(弧形）

-(void)presentController:(UIViewController*)controller fromRootController:(UIViewController*)rootController withSize:(CGSize)size
{
    UINavigationController* nav = [[UINavigationController alloc] initWithRootViewController:controller];
    nav.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    nav.modalPresentationStyle = UIModalPresentationFormSheet;
    [rootController presentModalViewController:nav animated:YES];
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)
    {
        nav.view.superview.backgroundColor = [UIColor clearColor];
        nav.view.bounds = CGRectMake(0, 0, size.width, size.height);
    }
    else
    {
        nav.view.superview.bounds = CGRectMake(0, 0, size.width, size.height);
    }
}

Answer 3

composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil];
composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:composeTweetController animated:TRUE];
//if you want to change its size but the view will remain centerd on the screen in both portrait and landscape then:
composeTweetViewController.view.superview.bounds = CGRectMake(0, 0, 320, 480);
//or if you want to change it's position also, then:
composeTweetViewController.view.superview.frame = CGRectMake(0, 0, 320, 480);

Answer 4

从iOS7开始，你可以简单地做到

composeTweetController.preferredContentSize = CGSizeMake(380.0, 550.0);

Answer 5

使用XCode 4.5测试并适用于iOS 6

我在阅读了很多关于这里的提示后偶然发现了我的答案：

在viewWillAppear:(BOOL)animated方法中：

[super viewWillAppear:animated];

 //resize modal view
 self.view.superview.bounds = CGRectMake(0, 0, 432, 680);

在viewDidAppear:(BOOL)animated方法中：

CGPoint centerPoint = CGPointMake([[UIScreen mainScreen] bounds].size.width/2, [[UIScreen mainScreen] bounds].size.height/2);
self.view.superview.center = centerPoint;

我尝试将中心代码添加到与调整大小代码相同的位置，但这不起作用。出于某种原因，它仅在视图出现在屏幕上后才有效。

我猜测它与UIModalPresentationFormSheet的工作方式有关，因为当我在LLDB调试器中单步执行时，我注意到有一个变量_formSheetSize仍然是{540,620}。去图。

Answer 6

这适用于任何UIModalTransitionStyle

@interface BaseDialog ()

@property(nonatomic,assign) CGRect origFrame;

@end

@implementation BaseDialog

-(void)viewDidLoad{
    [super viewDidLoad];
    self.origFrame=self.view.frame;
}
-(CGSize)formSheetSize{
    return self.origFrame.size;
}

Answer 7

以下代码是如何呈现模型视图控制器

 composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil];
    composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet;
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:composeTweetController];
    navigationController.delegate = self;   
    [self presentModalViewController:navigationController animated:YES];

并在您的ComposeTweet控制器类

中

-(void)viewWillAppear:(BOOL)animated
{
 [super viewWillAppear:animated];
 self.navigationController.view.superview.frame = CGRectMake(0, 0,500,400);
}

Answer 8

iOS 7

因此，设置superview的框架或边界的方法在iOS 7上不再起作用（对于UIModalTransitionStyleCoverVertical）。但是，您现在可以将超视图的背景颜色设置为清除，然后根据您的需要更改模态视图控制器的框架。

所以在iOS 7中你需要：

呈现视图控制器（演示模式：UIModalPresentationFormSheet）
设置视图控制器superview背景颜色以清除
根据需要更改视图控制器的框架（可能使其更小，然后将其置于超视图中）

Answer 9

我从UIPresentationFormSheet获得了一个全屏模式视图，只有这一行：

modalViewController.view.superview.bounds = CGRectMake(0, 0, 1024, 748);

Answer 10

@bdrobert遗憾的是，你的漂亮解决方案在 iOS6 上不再有效 - 即使新的viewcontroller嵌入了自定义大小，容器也保持原始大小。

您可能需要使用 iOS5 中引入的包含API，但您需要自己添加灰色背景，获取该区域的所有触摸事件。

Answer 11

在改变方向时，这段代码完美无缺......

settingViewController.modalPresentationStyle = UIModalPresentationFormSheet;

    [self presentViewController:settingViewController animated:YES completion:nil];

    settingViewController.view.superview.frame = CGRectMake(0, 0, 700, 700);

    UIInterfaceOrientation currentOrientation = [self getDeviceOrientation];

    if(currentOrientation == UIInterfaceOrientationPortrait || currentOrientation == UIInterfaceOrientationPortraitUpsideDown)
    {
            CGPoint centerPoint = CGPointMake([[UIScreen mainScreen] bounds].size.width/2, [[UIScreen mainScreen] bounds].size.height/2);
            settingViewController.view.superview.center = centerPoint;
    }
    else
    {
        CGPoint centerPoint = CGPointMake([[UIScreen mainScreen] bounds].size.height/2, [[UIScreen mainScreen] bounds].size.width/2);
        settingViewController.view.superview.center = centerPoint;
    }

Answer 12

现代ios13方式：

使用弹出窗口（表单和页面忽略preferredContentSize）

然后设置或覆盖import jaydebeapi, sys #Enter the values for you database connection dsn_database = "testdb"# e.g. "BLUDB" Name of the database dsn_hostname = "localhost"# e.g.: "bluemix05.bluforcloud.com" dsn_port = "50000"# e.g. "50000" Database port number dsn_uid = "DB2INST1"# e.g. "dash104434" User id dsn_pwd = "123456789"# e.g. "7dBZ3jWt9xN6$o0JiX!m" User password for the database connection_string='jdbc:db2://'+dsn_hostname+':'+dsn_port+'/'+dsn_database if (sys.version_info >= (3,0)): conn = jaydebeapi.connect("com.ibm.db2.jcc.DB2Driver", connection_string, [dsn_uid, dsn_pwd]) else: conn = jaydebeapi.connect("com.ibm.db2.jcc.DB2Driver", [connection_string, dsn_uid, dsn_pwd]) [1]: https://www.ibm.com/support/knowledgecenter/en/SSGNPV_1.1.3/dsx/createconnectionsdirect.html，又名Ed Pilowat＆Co

视图大小是固定的。如果你想要不同的东西，你必须自己实施。
