我有一些問題,嘗試使用SBJson JSON來分析,我做了一些研究,我無法找到的東西有幫助...SBJson Execptions解析後(__NSArrayM objectForKey :)
我跟着如何一些博客做到這一點,但我仍然得到這個錯誤:「__NSArrayM objectForKey:」
所以這是的Json我試圖解析:
{
"result": [
{
"authors": [
"Eric Ries"
],
"bc": 9780671607,
"title": "Yeah",
"urlImage": "www.yeah.hey",
"description": "Hey..."
}
]
}
這是我使用的代碼:
SBJsonParser *json;
NSDictionary *jsonResults;
NSError *jsonError;
json = [ SBJsonParser new ];
// Get result in a NSDictionary
jsonResults = (NSDictionary*) [ json objectWithString:output error:&jsonError ];
// Check if there is an error
if (jsonResults == nil) {
NSLog(@"Erreur lors de la lecture du code JSON (%@).", [ jsonError localizedDescription ]);
} else {
NSDictionary *book = (NSDictionary *)[ jsonResults objectForKey:@"result"];
NSArray *items = (NSArray *) [book objectForKey:@"title"];
}
錯誤:
-[__NSArrayM objectForKey:]: unrecognized selector sent to instance 0x7a2d390

並通過objectForKey
[book valueForKey:@"title"];
使用valueForKey這一翻譯我得到這個:
(
"Yeah"
)
而不是僅僅呀
而且我不想再解析(「是啊」 )至少得到是啊...
非常感謝!它像一個魅力:) – BaNz
