iOS JSON字符串转Dictionary - (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString { if (jsonString == nil) { return nil; } NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSError *error; NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&...
-(NSString *)convertToJsonData:(NSDictionary *)dict { NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error]; NSString *jsonString; if (!jsonData) { NSLog(@"%@",error); }else{ jsonString = [[NSString alloc]init...
return[NSStringstringWithString:s]; } 3.读取文本文件内容POST方法上传,参数放在body内 - (void)uploadJsonStringAsyn{ //读取txt文件内容(包含回车空格等特殊字符)转为jsonString NSMutableDictionary*params = [[NSMutableDictionaryalloc] init]; NSString*midiPath = [[NSBundlemainBundle] pathForResource:@"tes...
[mutStr replaceOccurrencesOfString:@"\n" withString:@"" options:NSLiteralSearch range:range2]; return mutStr; } 2. JSON字符串转化为字典 + (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString {if (jsonString ==nil) {returnnil; } NSData *jsonData = [jsonString dataUsingEncoding...
{ifletdata=jsonStr.data(using:.utf8){do{letdict=tryJSONSerialization.jsonObject(with:data,options:[])as?[String:Any]returndict}catch{print("Error converting JSON string to dictionary:\(error)")returnnil}}returnnil}// 使用示例letjsonStr="{\"name\": \"John\", \"age\": 30}"iflet...
在上面的示例代码中,我们创建了一个Json字符串jsonString,然后使用data(using: .utf8)方法将其转换为NSData对象。如果转换失败,我们可以在guard语句的else分支中处理错误情况。 步骤2:解析NSData对象为NSDictionary 接下来,我们需要使用NSJSONSerialization类将NSData对象解析为NSDictionary。
2. 字典转Json字符串 // 字典转json字符串⽅法 -(NSString *)convertToJsonData:(NSDictionary *)dict { NSError *error;NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPrettyPrinted error:&error];NSString *jsonString;if (!jsonData) { NSLog(@"%@",error);...
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&err];if(err) { NSLog(@"json解析失败：%@",err);return nil;} return dic;} + (NSString*)dictionaryToJson:(NSDictionary *)dic { NSError *parseError = nil;NSData *jsonData = [...
1 直接使用方法：- (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString { if (jsonString == nil) { return nil; } NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; NSError *err; NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData options:NS...
