如何将此脚本安装到 PhoneGap for iOS 中

Question

我不了解任何 Objective-C，这就是我使用 PhoneGap 来创建 iOS 应用程序的原因。 iOS 版 PhoneGap 存在一个很大的缺陷。键盘上经常有表单助手（“下一个”、“上一个”和“完成”按钮。）网上关于如何摆脱这个的信息很少，所有关于它的 Stackoverflow 问题都说它实际上是不可能的。但过了一段时间我偶然发现了这个教程。底部段落告诉您如何做到这一点。它有效，我下载并测试了完成的应用程序。

但由于我不知道如何在 Xcode 或 Objective-C 中执行几乎所有操作，因此我不知道这两部分代码会进入哪些文件，他在教程中没有说。

谁能告诉我它在 PhoneGap 应用程序文件中的位置？我非常感激，这已经困扰我一整天了。

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];

还有这个

RichTextEditorViewController *viewController = [[RichTextEditorViewController alloc] initWithNibName:@"RichTextEditorViewController" bundle:nil];
self.viewController = [[UINavigationController alloc] initWithRootViewController:viewController];

还有这个

- (void)removeBar {
    // Locate non-UIWindow.
    UIWindow *keyboardWindow = nil;
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
        if (![[testWindow class] isEqual:[UIWindow class]]) {
            keyboardWindow = testWindow;
            break;
        }
    }

    // Locate UIWebFormView.
    for (UIView *possibleFormView in [keyboardWindow subviews]) {       
        // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
        if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
            for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
                if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                    [subviewWhichIsPossibleFormView removeFromSuperview];
                }
            }
        }
    }
}

谢谢！

我发现自己需要这样做。我是一名 IOS 开发人员，但需要使用 PhoneGap 来降低多平台开发的成本。

无论如何，我修复了你的代码。因为，我猜，你不想花时间学习 obj-c，你只需要用以下内容替换 MainViewController.m 的内容：

#import "MainViewController.h"

@implementation MainViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    }
    return self;
}

- (void)didReceiveMemoryWarning
{
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

#pragma mark - View lifecycle

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

- (void) removeBar {
    // Locate non-UIWindow.
    UIWindow *keyboardWindow = nil;
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
        if (![[testWindow class] isEqual:[UIWindow class]]) {
            keyboardWindow = testWindow;
            break;
        }
    }

    // Locate UIWebFormView.
    for (UIView *possibleFormView in [keyboardWindow subviews]) {       
        // iOS 5 sticks the UIWebFormView inside a UIPeripheralHostView.
        if ([[possibleFormView description] rangeOfString:@"UIPeripheralHostView"].location != NSNotFound) {
            for (UIView *subviewWhichIsPossibleFormView in [possibleFormView subviews]) {
                if ([[subviewWhichIsPossibleFormView description] rangeOfString:@"UIWebFormAccessory"].location != NSNotFound) {
                    [subviewWhichIsPossibleFormView removeFromSuperview];
                }
            }
        }
    }
}

- (void)keyboardWillShow:(NSNotification*) notification {
    // remove the bar in the next runloop (not actually created at this point)
    [self performSelector:@selector(removeBar) withObject:nil afterDelay:0];
}

@end

作为警告，这是一个有点 hacky 的解决方案（但随后使用phonegap也是如此！），并且可能会在未来版本的iOS中中断。但我想我们会解决这个问题......

有许多 PhoneGap 插件可以增强键盘的控制。虽然我还没有使用过这个，但看起来离子键盘插件可能会提供您想要做的事情。

“隐藏带有下一个、上一个和完成按钮的键盘附件栏。”
方法：cordova.plugins.Keyboard.hideKeyboardAccessoryBar

添加它：
