如上所述,我正在从URL读取JSON文件。如果我访问页面,JSON格式是有效和好的。在应用程序中,我得到它:
NSURLSession *session = [NSURLSession sharedSession];
[[session dataTaskWithURL:[NSURL URLWithString:urlAsString]
completionHandler:^(NSData *data,
NSURLResponse *response,
NSError *error) {
if (error) {
NSLog(@"Error");
} else {
alreadyParsed = true;
NSMutableDictionary* object = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
NSMutableDictionary *posts = [object valueForKey:@"posts"];
if (!object) {
NSLog(@"Error parsing JSON: %@", error);
} else {
for (NSMutableDictionary *item in posts) {
NSLog(@"Item: %@", item);
}
}
NSLog(@"Data: %@", [object description]);
}
}] resume];
在页面上,JSON看起来像:
{
"status": "ok",
"count": 1,
"count_total": 39,
"pages": 39,
"posts": [
{
"id": 948564,
"title": "",
"modified": "2016-02-17 21:32:26",
"attachments": [],
"attachments_featured": [
{}]
},
{
"id": 948565,
"title": "",
"modified": "2016-02-17 21:32:26",
"attachments": []
}]
}
但是在app中,我得到了:
2016-02-29 17:04:34.819 test[22835:1929421] Data: {
count = 1;
"count_total" = 39;
pages = 39;
posts = (
{
attachments = (
);
.
.
.
在帖子数组和附件之间应该有更多的数据,但我无法弄清楚发生了什么以及为什么它没有显示。
我尝试将页面数据转换为字符串并打印它并显示正常。还尝试将字符串转换为NSData并创建JSON,但结果是相同的。任何人都知道发生了什么事?
