在这个特定的词典中，我只是得到了这个。其他显示正确数据的其他词典。 所以，我希望在这里得到回应，
"title: Re: Robin - Implementing Faveo Help Desk. Let’s get you started."
即使它没问题，我也会得到这种格式，然后有任何解决方案可以获得实际数据，因此我将在视图控制器中打印。
代码是，
这里我发送请求，
-(void)reload

这里是cellForRowAtIndexPath方法，

好的，首先字符串是Q-encode，并且是来自电子邮件的MIME标题。
“Q”编码类似于RFC 1521中定义的“Quoted-Printable”内容传输编码。它旨在允许在ASCII终端上无需解码就可以在ASCII终端上解密包含大多数ASCII字符的文本。
任何8位值都可以用“=”后跟两个十六进制数字表示。例如，如果使用的字符集是ISO-8859-1，那么“=”字符将被编码为“= 3D”，并且空格被编码为“= 20”。 （大写应该用于十六进制数字“A”到“F”。）
8位十六进制值20（例如，ISO-8859-1 SPACE）可能是 表示为“”（下划线，ASCII 95）。 （这个角色可能没有 通过一些互联网邮件网关，但它的使用将大大增加 使用没有的邮件阅读器增强“Q”编码数据的可读性 支持此编码。）请注意，“”始终表示 十六进制20，即使SPACE字符占用不同的代码 在使用的字符集中的位置。
8位值，对应于除以外的可打印ASCII字符 “=”，“？”，“_”（下划线），以及SPACE可以表示为那些 字符。 （但请参阅第5节的限制。）

此问题已在其他stackoverflow的帖子中解决：
在上面的帖子中显示了一个代码段代码，用于替换带有base 64支持的Q编码字符串，并将其转换为有效的NSString格式：
@implementation NSString (MimeEncodedWord)
- (BOOL) isMimeEncodedWord
{
return [self hasPrefix:@"=?"] && [self hasSuffix:@"?="];
}
+ (NSString*) stringWithMimeEncodedWord:(NSString*)word
{ // Example: =?iso-8859-1?Q?=A1Hola,_se=F1or!?=
NSArray *components = [word componentsSeparatedByString:@"?"];
if (components.count < 5) return nil;
NSString *charset = [components objectAtIndex:1];
NSStringEncoding encoding = CFStringConvertEncodingToNSStringEncoding(CFStringConvertIANACharSetNameToEncoding((CFStringRef)charset)); // TODO: What happens if the encoding is invalid?
NSString *encodingType = [components objectAtIndex:2];
NSString *encodedText = [components objectAtIndex:3];
if ([encodingType isEqualToString:@"Q"])
{ // quoted-printable
encodedText = [encodedText stringByReplacingOccurrencesOfString:@"_" withString:@" "];
encodedText = [encodedText stringByReplacingOccurrencesOfString:@"=" withString:@"%"];
NSString *decoded = [encodedText stringByReplacingPercentEscapesUsingEncoding:encoding];
return decoded;
} else if ([encodingType isEqualToString:@"B"])
{ // base64
NSData *data = [QSStrings decodeBase64WithString:encodedText];
NSString *decoded = [[NSString alloc] initWithData:data encoding:encoding];
return decoded;
} else {
NSLog(@"%@ is not a valid encoding (must be Q or B)", encodingType);
return nil;
}
}
@end
此代码也可以在Github帖子中找到，作为NSString类类别 在这里：https://github.com/hpique/NSString-MimeEncodedWord

检查以下代码，我希望它能工作。我根据你的代码创建..！此代码取自@Sophy Swicz。
NSString *encodedString =[finaldic objectForKey:@"title"];
[Utils isEmpty:encodedString];
if ([Utils isEmpty:encodedString]){
cell.ticketSubLabel.text=@"No Title";
}
else
{
NSMutableString *decodedString = [[NSMutableString alloc] init];
if ([encodedString hasPrefix:@"=?UTF-8?Q?"] || [encodedString hasSuffix:@"?="])
{
NSScanner *scanner = [NSScanner scannerWithString:encodedString];
NSString *buf = nil;
// NSMutableString *decodedString = [[NSMutableString alloc] init];
while ([scanner scanString:@"=?UTF-8?Q?" intoString:NULL]
|| ([scanner scanUpToString:@"=?UTF-8?Q?" intoString:&buf] && [scanner scanString:@"=?UTF-8?Q?" intoString:NULL])) {
if (buf != nil) {
[decodedString appendString:buf];
}
buf = nil;
NSString *encodedRange;
if (![scanner scanUpToString:@"?=" intoString:&encodedRange]) {
break; // Invalid encoding
}
[scanner scanString:@"?=" intoString:NULL]; // Skip the terminating "?="
// Decode the encoded portion (naively using UTF-8 and assuming it really is Q encoded)
// I'm doing this really naively, but it should work
// Firstly I'm encoding % signs so I can cheat and turn this into a URL-encoded string, which NSString can decode
encodedRange = [encodedRange stringByReplacingOccurrencesOfString:@"%" withString:@"=25"];
// Turn this into a URL-encoded string
encodedRange = [encodedRange stringByReplacingOccurrencesOfString:@"=" withString:@"%"];
// Remove the underscores
encodedRange = [encodedRange stringByReplacingOccurrencesOfString:@"_" withString:@" "];
// [decodedString appendString:[encodedRange stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *str1= [encodedRange stringByRemovingPercentEncoding];
[decodedString appendString:str1];
}
NSLog(@"Decoded string = %@", decodedString);
cell.ticketSubLabel.text= decodedString;
}
else{
cell.ticketSubLabel.text= encodedString;
}
}
