iphone - SMS 窗口不会关闭 objective-C

Question

您好，我正在尝试为 adobe AIR 制作 SMS 原生扩展。我之前没有用 objective-c 编码，但除了按下发送或取消时 SMS 窗口不会关闭之外，一切正常。下面是代码的主要部分，但如果您需要更多信息，请问我。谢谢阅读。还有为什么 xcode 告诉我:第二行的“协议(protocol)中的方法未实现”？

#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:

Omar 非常感谢您的回答，而且回答得这么快!首先，我尝试了您使用

的解决方案

[controller dismissModalViewControllerAnimated:YES];

但这没有任何作用，所以我把它改回来了。我的标题已经是:

@interface SMSComposerHelper : NSObject<MFMessageComposeViewControllerDelegate> {

所以我决定专注于修复警告。通过更改解决了警告:

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

到:

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

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

[controller dismissModalViewControllerAnimated:YES];

成功了!!!!非常感谢，伙计。你不知道我被困了多少个小时。我很乐意接受你的回答。

代替

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

写

 [controller dismissModalViewControllerAnimated:YES];

也为警告

转到 SMSComposerHelper.h并添加以下内容

@interface SMSComposerHelper : UIViewController<MFMessageComposeViewControllerDelegate>{

代替

@interface SMSComposerHelper : UIViewController{
