MFMessageComposeViewController 禁用编辑文本条目？
MFMessageComposeViewController disable editing text entry?
你好 Whosebug 的朋友，
我正在集成一个 MFMessageViewController，我想通过禁止键盘出现或禁止用户与之交互来禁用它的编辑区域。目前我的代码是：
import UIKit
import MessageUI
class ViewController: UIViewController,MFMessageComposeViewControllerDelegate,UITextFieldDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
@IBAction func sendSmsClick(_ sender: AnyObject) {
guard MFMessageComposeViewController.canSendText() else {
return
}
let messageVC = MFMessageComposeViewController()
UIButton.appearance(whenContainedInInstancesOf: [MFMessageComposeViewController.self]).isUserInteractionEnabled = false
messageVC.body = "Enter a message hjhjhjkhjkhjhjhjjhgjhghjgjhghjghjghjghjgjhghjghjgjhghjghjghghjghjghjghghjghjhjghjghjghhvvvbnvhvhghghguyguygyugugigiugiouiopuopuoppuuo";
messageVC.recipients = ["Enter tel-nr"]
messageVC.messageComposeDelegate = self;
NSLog("Subviews %@", messageVC.view.subviews);
// self.view.endEditing(true)
self.present(messageVC, animated: false) {
// self.getAllSubviews(view: messageVC.view)
messageVC.view.loopViewHierarchy { (view, stop) in
if view is UIButton {
/// use the view
print("here")
stop = true
}
}
}
}
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
switch (result.rawValue) {
case MessageComposeResult.cancelled.rawValue:
print("Message was cancelled")
self.dismiss(animated: true, completion: nil)
case MessageComposeResult.failed.rawValue:
print("Message failed")
self.dismiss(animated: true, completion: nil)
case MessageComposeResult.sent.rawValue:
print("Message was sent")
self.dismiss(animated: true, completion: nil)
default:
break;
}
}
它工作正常，我只想了解键盘上方的特定 UIElement，我想禁用它以进行进一步编辑。我怎样才能做到这一点？
您可以尝试打印视图层次结构并从子视图中找到您的文本字段，问题是 - 所有这些 UI 都 运行 到与您的应用程序不同的环境中，您不会在那里找不到任何有用的东西。
/// Helper for printing view hierarchy recursively
extension UIView {
func printViewHierarchy() {
print(self)
for view in self.subviews {
view.printViewHierarchy()
}
}
}
self.present(messageVC, animated: true, completion: {
// Try printing the view hierarchy after it has been loaded on to screen
messageVC.view.printViewHierarchy()
})
// Here's what's printed by above
<UILayoutContainerView: 0x100a04990; frame = (0 0; 375 627); clipsToBounds = YES; autoresize = W+H; gestureRecognizers = <NSArray: 0x28100ef10>; layer = <CALayer: 0x281eac720>>
<UINavigationTransitionView: 0x100c0e0d0; frame = (0 0; 375 627); clipsToBounds = YES; autoresize = W+H; layer = <CALayer: 0x281eee860>>
<UIViewControllerWrapperView: 0x100c0f990; frame = (0 0; 375 627); autoresize = W+H; layer = <CALayer: 0x281e975e0>>
<UIView: 0x103b04900; frame = (0 0; 375 627); autoresize = W+H; layer = <CALayer: 0x281e8aa80>>
<_UISizeTrackingView: 0x103a05f80; frame = (0 0; 375 627); clipsToBounds = YES; autoresize = W+H; layer = <CALayer: 0x281e84c60>>
<_UIRemoteView: 0x103a077f0; frame = (0 0; 375 667); userInteractionEnabled = NO; layer = <CALayerHost: 0x281e84b20>>
这 _UIRemoteView 会妨碍您，您将无法在视图层次结构中找到您的目标 textField/button。
我们还能做什么？
Use private apis that will most likely get us a rejection from App Store.
如何找到我们可以使用哪些私有 api？
ObjectiveC.runtime provides you ways to inspect class details (public + private).
import ObjectiveC.runtime
func printClassDetails(_ targetClass: AnyClass) {
var varCount: UInt32 = 0
let iVars = class_copyIvarList(targetClass, &varCount)
var index = 0
if let iVars = iVars {
while index < varCount-1 {
let iVar = iVars[index]
if let name = ivar_getName(iVar) {
print("iVar ------------> \(String(cString: name))")
}
index += 1
}
}
free(iVars)
index = 0
let methods = class_copyMethodList(targetClass, &varCount)
if let methods = methods {
while index < varCount-1 {
let method = methods[index]
let selector = method_getName(method)
print("method ------------> \(NSStringFromSelector(selector))")
index += 1
}
}
free(methods)
}
使用上面的代码，如果您尝试检查 MFMessageComposeViewController class，您将看到以下内容。
printClassDetails(MFMessageComposeViewController.self)
iVar ------------> _internal
iVar ------------> _messageComposeDelegate
iVar ------------> _recipients
iVar ------------> _body
iVar ------------> _subject
iVar ------------> _message
iVar ------------> _currentAttachedVideoCount

iVar ------------> _currentAttachedImageCount
iVar ------------> _UTITypes
iVar ------------> _photoIDs
iVar ------------> _cloudPhotoIDs
iVar ------------> _contentText
iVar ------------> _contentURLs
iVar ------------> _chatGUID
iVar ------------> _groupName

method ------------> setUTITypes:

method ------------> viewDidAppear:

method ------------> smsComposeControllerCancelled:

method ------------> contentURLs
method ------------> shareSheetSessionID
method ------------> disableUserAttachments
method ------------> setCurrentAttachedVideoCount:
method ------------> setCurrentAttachedAudioCount:
method ------------> setCurrentAttachedImageCount:
method ------------> _MIMETypeForURL:
method ------------> _isVideoMIMEType:
method ------------> _isAudioMIMEType:
method ------------> _isImageMIMEType:
method ------------> _contentTypeForMIMEType:
method ------------> _updateAttachmentCountForAttachmentURL:

method ------------> _setCanEditRecipients:
method ------------> _setShouldDisableEntryField:
method ------------> messageComposeDelegate

method ------------> currentAttachedAudioCount
_setShouldDisableEntryField 看起来很有趣。如何使用？
let messageVC = MFMessageComposeViewController()
messageVC.body = "Enter a message"
messageVC.recipients = ["Test Telephone #"]
let name = [":","d","l","e","i","F","y","r","t","n","E","e","l","b","a","s","i","D","d","l","u","o","h","S","t","e","s","_"].reversed().joined()
let sel = NSSelectorFromString(name)
if messageVC.responds(to: sel) {
messageVC.perform(sel, with: true)
}
self.present(messageVC, animated: true, completion: nil)
有效吗？
As of Xcode 12.5 & iOS 14.6 - it does.
为什么要费那么大劲才能找到选择器名称？
也许（这是一个很大的可能）这将有助于避免像下面这样的拒绝。
