searchEnum.json 3、登陆成功之后就请求接口更新DictionariesEnum 数据 I、数组转json 字符串的应用案例 (lldb) po [[NSString alloc] initWithData: [NSJSONSerialization [[NSBundle mainBundle] pathForResource:@"searchEnum.json" ofType:nil]; // NSArray *array = [NSJSONSerialization NSData *data = [NSData dataWithContentsOfFile:filePath];//获取指定路径的data文件 id json = [NSJSONSerialization
NSData *data = [[NSData alloc] initWithContentsOfFile:path]; // 对数据进行JSON格式化并返回字典形式 return [NSJSONSerialization filePath = [NSHomeDirectory() stringByAppendingString:@"/Documents/myJson.json"]; NSData *json_data = [NSJSONSerialization
DataTOjsonString: (id)object { NSString*jsonString = nil; NSError *error; NSData *jsonData = [NSJSONSerialization 串转化为字典或者数组 - (id)toArrayOrNSDictionary: (NSData*)jsonData{ NSError *error = nil; id jsonObject = [NSJSONSerialization qingjoin/p/3437036.html 将NSString转换成UTF8编码的NSString http://blog.csdn.net/a6472953/article/details/8163016 NSJSONSerialization-JSON
转换思路:将某个对象先通过NSJSONSerialization转换成NSData对象,然后将这个NSData对象转换成字符串,这样得到的字符串就是JSON字符串。(是不是很简单!) )object{ NSString *jsonString = [[NSString alloc]init]; NSError *error; NSData *jsonData = [NSJSONSerialization object { NSString *jsonString = [[NSString alloc]init]; NSError *error; NSData *jsonData = [NSJSONSerialization

parmeter——我们要传递给WKWebview中的参数,通常用NSJSONSerialization转化为字符串来传递。 该参数会在completionHandler的回调函数中以字符串返回,通常是用NSJSONSerialization来解析。
sStr forType:NSStringPboardType]; 6.数组转字符串 NSData *sData = nil; NSString * sStr = nil; sData = [NSJSONSerialization stringByReplacingOccurrencesOfString:@"\\/" withString:@"/"]; data转换 NSData * sData = nil; NSString * sStr = nil; sData = [NSJSONSerialization
NSNull JSON 转换为 OC数据类型 3.在iOS中,JSON的常见解析方案有4种 ①第三方框架:JSONKit、SBJson、TouchJSON(性能从左到右,越差) ②苹果原生(自带):NSJSONSerialization (性能最好) NSJSONSerialization的常见方法 JSON数据 -> OC对象 /* 第一个参数:需要解析的JSON数据 第二个参数:解析JSON的可选配置参数 JSONObjectWithData:(NSData *)data options:(NSJSONReadingOptions)opt error:(NSError **)error; iOS5自带解析类NSJSONSerialization 从response中解析出数据放到字典中 NSDictionary *weatherDic = [NSJSONSerialization JSONObjectWithData:response 查看复杂的JSON数据 ①在线转换,查看格式化 http://tool.oschina.net/codeformat/json ②直接将转换后的数据写到本地 NSDictionary *Dic = [NSJSONSerialization
if ([json isKindOfClass:[NSData class]]) { jsonData = json; } // 如果时NSData类型,使用NSJSONSerialization jsonData && [jsonData isKindOfClass:[NSData class]]) { NSError *error = nil; dict = [NSJSONSerialization
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"%@", [NSJSONSerialization completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"%@", [NSJSONSerialization completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { NSLog(@"%@", [NSJSONSerialization
以下是一个简单的JSON解析示例: 复制 NSError *jsonError; NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData NSLog(@"Error: %@", error); } else { // 解析音频信息 NSDictionary *audioData = [NSJSONSerialization
operation.responseString; NSData* data=[html dataUsingEncoding:NSUTF8StringEncoding]; id dict=[NSJSONSerialization

json string - (NSString *)convertJSONStringWithObject:(id)jsonObject { NSData *jsonData; if ([NSJSONSerialization isValidJSONObject:jsonObject]) { NSError *error; jsonData = [NSJSONSerialization dataWithJSONObject
