JSON解析：NSArray POST

Question

如何在JSON中POST NSArray值或是否有任何可能的POST JSON值。

Answer 1

我的東西，這是非常有用的，否則我修改一些代碼

NSMutableArray * arr = [[NSMutableArray alloc] init]; 
// assume that this is your Array 
[arr addObject:@"1"]; 
[arr addObject:@"2"]; 

// convert the NSArray to NSdata , the reason is always the web service get string only 
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:arr options:NSJSONWritingPrettyPrinted error:&error]; 
NSString *jsonString = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding]; 
NSLog(@"jsonData as string:\n%@", jsonString); 
// finally append the -- jsonString to your web service
