（客服云）iOS访客端接收图文消息不展示封面图片怎么办？
将HDBubbleView.h+Article.m中的- (instancetype)initWithDictionary:(NSDictionary *)dic方法改成下面这样就可以了
- (instancetype)initWithDictionary:(NSDictionary *)dic {
self = [super init];
if (dic != nil) {
_type = HDCellTypeSub;
_title = [dic objectForKey:@"title"];
double createTime = [[NSDate date] timeIntervalSince1970] * 1000;
if ([dic objectForKey:@"createdTime"]) {
createTime = [[dic objectForKey:@"createdTime"] doubleValue];
}
_createTime = [self timeFormatter:createTime/1000];
_digest = [dic objectForKey:@"digest"];
// //封面展示缩略图
// NSString *thumbUrl = [dic objectForKey:@"thumbUrl"];
// if (thumbUrl) {
// if (thumbUrl && [thumbUrl hasPrefix:@"http"]) {
// _imageUrl = thumbUrl;
// }else {
// _imageUrl = [NSString stringWithFormat:@"%@%@",[HDClient.sharedClient kefuRestServer], thumbUrl];
// }
// }
// 封面展示原图
NSString *picUrl = [dic objectForKey:@"picurl"];
if (picUrl) {
if (picUrl && [picUrl hasPrefix:@"http"]) {
_imageUrl = picUrl;
}else {
_imageUrl = [NSString stringWithFormat:@"%@%@",[HDClient.sharedClient kefuRestServer], picUrl];
}
}
NSString *detailUrl = [dic objectForKey:@"url"];
if (detailUrl) {
if (detailUrl && [detailUrl hasPrefix:@"http"]) {
_url = detailUrl;
}else {
_url = [NSString stringWithFormat:@"%@%@",[HDClient.sharedClient kefuRestServer], detailUrl];
}
}
}
return self;
}
