问题描述
对于我希望以下面提到的格式创建JSON的应用程序,
For an application i want to create a JSON in format as mentioned below,
"Students" : {

"Grade1": {
"studentresult": "pass",
"marksheet": "provided"
},
"ID": 01,
"Name": "Student1",

}
我使用以下代码创建相同的,
I am using the following code to create the same,
NSMutableDictionary *gradedetails = [[NSMutableDictionary alloc] init];
[gradedetails setObject:@"pass" forKey:@"studentresult"];
[gradedetails setObject:@"provided" forKey:@"marksheet"];
NSMutableDictionary *sdetails = [[NSMutableDictionary alloc] init];
[sdetails setObject:@"01" forKey:@"ID"];
[sdetails setObject:@"Name" forKey:@"Student1"];
NSMutableDictionary *grade = [[NSMutableDictionary alloc] init];
[grade setObject:gradedetails forKey:@"Grade1"];
NSMutableArray *rarray = [[NSMutableArray alloc] init];
[rarray addObject:grade];
[rarray addObject:sdetails];
NSMutableDictionary *results = [[NSMutableDictionary alloc] init];
[results setObject:rarray forKey:@"results"];
NSMutableDictionary *stud = [[NSMutableDictionary alloc] init];
[stud setObject:rdic forKey:@"Students"];
NSData *jsondata = [NSJSONSerialization dataWithJSONObject:stud options:NSJSONWritingPrettyPrinted error:&error];
我收到以下格式,
"Students" : {
"results" : [
{
"Grade1" : {
"studentresult" : "pass",
"marksheet" : "provided"
}
},
{
"ID" : "01",
"Name" : "Student1"
}
]
}
}
有人可以帮我创建格式。

推荐答案
所需数据,您可以这样做。只需转换JSon中的stud dict或任何其他您想要的格式。删除该数组,你不需要它,正如你所提到的那样。
Required Data , You can get this way . Just convert that stud dict in JSon or any other format you want. Remove that array , You don't need it , As you mentioned it in the required format.
NSMutableDictionary *gradedetails = [[NSMutableDictionary alloc] init];
[gradedetails setObject:@"pass" forKey:@"studentresult"];
[gradedetails setObject:@"provided" forKey:@"marksheet"];
NSMutableDictionary *sdetails = [[NSMutableDictionary alloc] init];
[sdetails setObject:@"01" forKey:@"ID"];
[sdetails setObject:@"Name" forKey:@"Student1"];
[sdetails setObject:gradedetails forKey:@"Grade1"];
NSMutableDictionary *results = [[NSMutableDictionary alloc] init];
[results setObject:sdetails forKey:@"results"];
NSMutableDictionary *stud = [[NSMutableDictionary alloc] init];
[stud setObject:results forKey:@"Students"];
NSLog(@"Required Format Data is %@",stud);
