【转】NSJSONSerialization解析JSON数据，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
1 - (IBAction)touchWriteButton:(id)sender {
2 NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
3 [dictionary setValue:@"Anthony" forKey:@"First Name"];
4 [dictionary setValue:@"Robbins" forKey:@"Last Name"];
5 [dictionary setValue:[NSNumber numberWithUnsignedInteger:51] forKey:@"Age"];
6 NSArray *arrayOfAnthonysChildren = [[NSArray alloc] initWithObjects:@"Anthony's Son 1",@"Anthony's Daughter 1",@"Anthony's Son 2",@"Anthony's Son 3",@"Anthony's Daughter 2",nil]; 7 [dictionary setValue:arrayOfAnthonysChildren forKey:@"children"];
8 NSError *error = nil;
9 NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionary options:NSJSONWritingPrettyPrinted error:&error];
10 if (error) {
11 NSLog(@"dic->%@",error);
12 }
13 [dictionary release];
14 BOOL succeed = [jsonData writeToFile:JSON_PATH atomically:YES];
15 if (succeed) {
16 NSLog(@"Save succeed");
17 }else {
18 NSLog(@"Save fail");

NSData->JSON
1 - (IBAction)touchReadButton:(id)sender {
2 NSData *jsonData = [[NSData alloc] initWithContentsOfFile:JSON_PATH]; /* Now try to deserialize the JSON object into a dictionary */
3 NSError *error = nil;
4 id jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingAllowFragments error:&error];
5 if (jsonObject != nil && error == nil){
6 NSLog(@"Successfully deserialized...");
