Question

您好我正在尝试为adobe AIR制作短信本机扩展程序。我之前在Objective-c中编码但是一切正常，除了按下发送或取消时SMS窗口不会关闭的事实。下面是代码的主要部分，但问我是否还需要更多信息。谢谢阅读。为什么xcode告诉我：第二行的“协议中的方法没有实现”？

#import "SMSComposerHelper.h"
@implementation SMSComposerHelper

//Event name
static  NSString *event_name = @"SMS_COMPOSER_EVENT";


-(void) sendSMS:(NSString *)toRecipient
         messageBody:(NSString *)messageBody
{

    FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[@"WILL_SHOW_MAIL_COMPOSER" UTF8String]);

           MFMessageComposeViewController *smsComposer = [[MFMessageComposeViewController alloc] init];
          smsComposer.messageComposeDelegate = self;

    //make string into array
    NSArray *recipientArray;
    recipientArray = [NSArray arrayWithObjects: toRecipient, nil];

    smsComposer.body = messageBody;   
    smsComposer.recipients = recipientArray;

    //show sms composer
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentModalViewController:smsComposer animated:YES];

}


// Dismisses the sms composition interface when users tap Cancel or Send.
-(void) smsComposeController: (MFMessageComposeViewController*)controller didFinishWithResult: (MessageComposeResult)result error:(NSError*)error
{
    NSString *event_info = @"";
          // Notifies users about errors associated with the interface
          switch (result)
          {
                    case MessageComposeResultCancelled:
            event_info = @"SMS_CANCELED";
                              break;
        case MessageComposeResultSent:
            event_info = @"SMS_SENT";
                              break;
                    case MessageComposeResultFailed:
            event_info = @"SMS_FAILED";
                              break;
                    default:
            event_info = @"SMS_UNKNOWN";
            break;
          }

    FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[event_info UTF8String]);
    FREDispatchStatusEventAsync(context, (uint8_t*)[event_name UTF8String], (uint8_t*)[@"WILL_HIDE_SMS_COMPOSER" UTF8String]);

    context = nil;


    //hide mail composer
   [[[[UIApplication sharedApplication] keyWindow] rootViewController] dismissModalViewControllerAnimated:YES];
}

-(void)setContext:(FREContext)ctx {
    context = ctx;
}

@end

回应：

奥马尔非常感谢你的回答和快速回答！首先，我尝试了使用

的解决方案

[controller dismissModalViewControllerAnimated:YES];

但这没有做任何事情所以我改回来了。我的标题已经是：

@interface SMSComposerHelper : NSObject<MFMessageComposeViewControllerDelegate> {

所以我决定专注于修复警告。警告通过改变来解决：

-(void) smsComposeController: (MFMessageComposeViewController*)controller didFinishWithResult: (MessageComposeResult)result error:(NSError*)error

为：

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result

我很想知道为什么这有效？你认识奥马尔吗？所以我解决了警告，但它仍然没有解雇。所以我再次尝试了你的建议：

[controller dismissModalViewControllerAnimated:YES];

和它一起工作!!!! 非常感谢你。你不知道我被困多少小时。我很乐意接受你的回答。

Answer 1

而不是

 [[[[UIApplication sharedApplication] keyWindow] rootViewController] dismissModalViewControllerAnimated:YES];

写

 [controller dismissModalViewControllerAnimated:YES];

也是警告

转到SMSComposerHelper.h 并添加以下

@interface SMSComposerHelper : UIViewController<MFMessageComposeViewControllerDelegate>{

而不是

@interface SMSComposerHelper : UIViewController{

短信窗口不会解雇目标-C
