如何在 iOS 中使用 api 传递 json 对象

Question

https://api.coinbase.com/v1/transactions/send_money
用这个 api 传递波纹管参数。

{
  "transaction": {
    "to": "user1@example.com",
    "amount": "1.234",
    "notes": "Sample transaction for you"
  }
}

Answer 1

我得到了这个答案..

NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
        [dic setObject:@"user1@example.com" forKey:@"to"];
        [dic setObject:@"1.234" forKey:@"amount"];
        [dic setObject:@"sending money" forKey:@"notes"];

NSMutableDictionary *dic1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:dic,@"transaction", nil];

Answer 2

这是一个使用 Coinbase iOS SDK:

的完整示例

NSDictionary *transactionDict = @{
    @"to": @"user1@example.com",
    @"amount": @"1.234",
    @"notes": @"sending money" };
NSDictionary *params = @{ @"transaction": transactionDict };

[apiClient doPost:@"transactions/send_money" params:transactionDict completion:^(id result, NSError *error) {
    if (error) {
        NSLog(@"Could not send money: %@", error);
    } else {
        NSLog(@"Success: %@", [result objectForKey:@"transaction"]);
    }
}];
