我已经在插件中声明了我的iOS插件文件.xml如下所示:
<config-file target="config.xml" parent="/*">
<feature name="CDVOP">
<param name="ios-package" value="CDVOP"/>
</feature>
</config-file>
<header-file src="src/ios/CDVOP.h" />
<source-file src="src/ios/CDVOP.m" />
在插件JavaScript文件中,我有这个函数,我后来从JavaScript应用程序中调用了它
showCatPictures: function(interval) {
exec(null, null, 'CDVOP', 'showCatPictures', [interval]);
},
我正在运行从 xcode 使用此插件的应用程序来查看调试输出。当我调用showCatPictures
函数时,我得到这个:
OP Cordova Tests[1122:60b] ERROR: Plugin 'CDVOP' not found, or is not a CDVPlugin. Check your plugin mapping in config.xml.
2014-02-14 16:23:45.233 OP Cordova Tests[1122:60b] -[CDVCommandQueue executePending] [Line 127] FAILED pluginJSON = [

]
我怀疑这可能与我导入的所有东西有关,所以这里是 CDVOP.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <Cordova/CDVPlugin.h>
#import <Cordova/CDV.h>
#import <Cordova/CDVViewController.h>

@interface CDVOP : CDVPlugin <UIWebViewDelegate> {

UIImageView* selfImageView;
}

- (void) getAccountState:(CDVInvokedUrlCommand*)command;
- (void) startLoginProcess:(CDVInvokedUrlCommand*)command;
- (void) showCatPictures:(CDVInvokedUrlCommand*)command
@end
这是CDVOP.m的顶部:
#import "CDVOP.h"
@implementation CDVOP
@synthesize webView, selfImageView, peerImageView, callbackId;
-(CDVPlugin*) initWithWebView:(UIWebView*)theWebView
{
self = (CDVOP*)[super initWithWebView:theWebView];
NSLog(@">>> initializing with cordova webView <<<"); // actually this does not get called!
return self;
}
// stress test UIImageViews using a series of cat pictures
- (void)showCatPictures:(CDVInvokedUrlCommand*)command
{
//initialize and configure the image view
CGRect selfRect = CGRectMake(0, 0, 100.0, 200.0);
self.selfImageView = [[UIImageView alloc] initWithFrame:selfRect];
[self.webView.superview addSubview:self.selfImageView];
// load pictures and start animating
NSLog(@"displaying cat pictures");
selfImageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"1.JPG"], [UIImage imageNamed:@"2.JPG"], [UIImage imageNamed:@"3.JPG"],
[UIImage imageNamed:@"4.JPG"], [UIImage imageNamed:@"5.JPG"], [UIImage imageNamed:@"6.JPG"],
[UIImage imageNamed:@"7.JPG"], [UIImage imageNamed:@"8.JPG"], nil];
selfImageView.animationDuration = 0.3;
[selfImageView startAnimating];
}
任何想法为什么插件似乎没有正确初始化,为什么我不能用exec
调用它的方法?
这是我忘了在问题中提到的一个不重要的小细节。这就是使用该插件的示例应用程序中的www/config.xml
的外观。你能发现问题吗?

请注意应用程序名称中的空格 <name>My Cordova Test</name>
。这似乎一开始有效,但它在文件夹名称中放置了空格,稍后将托管您的插件。这足以干扰插件安装过程。这是我为解决问题所做的:
- 将测试应用的名称更改为
MyCordovaTest
-
cordova platform remove ios
-
cordova plugin remove org.myplugin.cordova
-
cordova platform add ios
-
cordova plugin add ../my-plugin
-
cordova build ios
现在插件已正确安装并按预期初始化。非常感谢IRC房间里#phonegap
好人帮我调试了这个问题。我希望这对某人有所帮助。
就我而言,当我在ios中遇到相同的问题时,错误在于插件.xml插件文件中
<config-file target="config.xml" parent="/*">
<feature name="UDPSender">
<param name="ios-package" value="UDPSender"/>
</feature>
</config-file>
该值与 swift 文件中的值不匹配,在 swift 文件中,类的开始是这样的
@objc(HWPUDPSender) public class UDPSender: CDVPlugin, GCDAsyncUdpSocketDelegate{
在这里我们可以看到插件.xml值是 UDPSender,但在 swift 文件中它是 HWPUDPSender,这两个应该是相同的
