如何更改UIActivityViewController的大小 [英] How to change the size the UIActivityViewController

问题描述

在我的应用中，我想共享图像，文本和网址.我这样做如下:

In my app, I want to share an image, text and url. I do that as follows:

UIActivityViewController *controller =  [[UIActivityViewController alloc]
                                             initWithActivityItems:@[text, url, image]
                                             applicationActivities:nil];

    controller.excludedActivityTypes = @[UIActivityTypePostToWeibo,
                                         //UIActivityTypeMessage,
                                         //UIActivityTypeMail,
                                         UIActivityTypePrint,
                                         UIActivityTypeCopyToPasteboard,
                                         UIActivityTypeAssignToContact,
                                         UIActivityTypeSaveToCameraRoll,
                                         UIActivityTypeAddToReadingList,
                                         UIActivityTypePostToFlickr,
                                         UIActivityTypePostToVimeo,
                                         UIActivityTypePostToTencentWeibo,
                                         UIActivityTypeAirDrop];

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

不幸的是，结果，模式对话框覆盖了我iPhone的整个屏幕，尽管它只显示四个共享图标.

Unfortunately, as a result, the modal dialog covers the whole screen of my iphone, although it only displays four share icons.

我认为这是不成比例的，并且希望调整控制器的高度，因此它只能容纳该行.

I think that is out of proportion, and would like to adjust the height of the controller, so it only accommodates that one needed row.

[更新]我在真实设备上运行此代码(iPhone 5s运行iOS 8的最新Beta版)，图像的大小似乎无关紧要.但是，在控制台中，我看到以下消息，这应该有助于解决此问题.

[Update] I am running this code on a real device (iPhone 5s running the very latest beta of iOS 8), and the size of the image doesn't seem to matter. However, in my console I see the following messages, that should help to fix the issue.

2014-09-17 15:24:27.068 AppName[1826:747596] Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSLayoutConstraint:0x17008a5a0 UIView:0x1781945d0.bottom == _UIAlertControllerView:0x13c51ea00.bottom>",
    "<NSLayoutConstraint:0x17008aeb0 V:|-(0)-[UIView:0x178194d20]   (Names: '|':_UIAlertControllerView:0x13c51ea00 )>",
    "<NSLayoutConstraint:0x17008af50 UIView:0x178194d20.bottom <= _UIAlertControllerView:0x13c51ea00.bottom>",
    "<NSLayoutConstraint:0x17008afa0 UIView:0x1781945d0.centerY == UIView:0x178194d20.centerY>",
    "<NSLayoutConstraint:0x17008a550 V:|-(>=8)-[UIView:0x1781945d0]   (Names: '|':_UIAlertControllerView:0x13c51ea00 )>"
)

感谢您到目前为止的反馈.

Thanks for your feedback so far.
