我已经为iOS在plugin.xml中声明了插件文件如下:
<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,我有一个函数,我后来从JavaScript应用程序调用了这个函数
showCatPictures: function(interval) {
exec(null, null, 'CDVOP', 'showCatPictures', [interval]);
},
我正在运行应用程序,它使用xcode中的这个插件来查看调试输出。当我调用showCatPictures
函数时,我会得到这样的结果:
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 = [

]
我怀疑这可能与我进口的所有东西有关,下面是CDVOP.h。
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <Cordova/CDVPlugin.h>
#import <Cordova/CDV.h>
#import <Cordova/CDVViewController.h>

#import "OpenpeerSDK/HOPAccount.h"
#import "OpenpeerSDK/HOPIdentity.h"
@interface CDVOP : CDVPlugin <UIWebViewDelegate> {
NSString* callbackId;
UIImageView* peerImageView;
UIImageView* selfImageView;
}
@property (nonatomic, copy) NSString* callbackId;
@property (retain, nonatomic) UIImageView *peerImageView;
@property (retain, nonatomic) UIImageView *selfImageView;
- (void) authorizeApp:(CDVInvokedUrlCommand*)command;
- (void) configureApp:(CDVInvokedUrlCommand*)command;
- (void) getAccountState:(CDVInvokedUrlCommand*)command;
- (void) startLoginProcess:(CDVInvokedUrlCommand*)command;
- (void) showCatPictures:(CDVInvokedUrlCommand*)command
@end
这是CDVOP.m的最上面部分:
#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];
}
想知道为什么插件没有被正确初始化,为什么我不能用exec
调用它的方法?

这里有一个小的不重要的细节,我忘了在问题中提到。这就是使用插件的示例应用程序中的www/config.xml
的样子。你能发现这个问题吗?
<widget id="org.sample.test" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<name>My Cordova Test</name>

<content src="index.html" />
<access origin="*" />
</widget>
注意应用程序名称<name>My Cordova Test</name>
中的空格。这似乎在一开始是可行的,但它会在文件夹名中放置空格,这将在稍后托管您的插件。这足以干扰插件安装过程。这就是我为解决这个问题所做的:
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,并按预期进行初始化。非常感谢#phonegap
IRC房间里的好心人,他们帮助我调试这个问题。我希望这能帮上忙。

在我的例子中,当我在ios中遇到同样的问题时,错误是插件的plugin.xml文件中的错误。
<config-file target="config.xml" parent="/*">
<feature name="UDPSender">
<param name="ios-package" value="UDPSender"/>
</feature>
</config-file>
这个值与当前文件中的值不匹配,在快速文件中,类的开头是这样的。
@objc(HWPUDPSender) public class UDPSender: CDVPlugin, GCDAsyncUdpSocketDelegate{
在这里我们可以看到在plugin.xml值是UDPSender,但是在快速文件中是HWPUDPSender,这两者应该是相同的。
