更改JSON字符串格式

Question

如何更改以下JSON结构，

[
    "registerDevice",
    {
        "type": "7",
        "pushBadge": "1",
        "pushSound": "1",
        "enabled": "1",
        "deviceToken": "e03d25f4f1bd40678cd693fe66fe7946ffdb03e1b23cfc5f9dc747fd5869fbcd",
        "pushAlert": "1"
    }
]

使用Objective-c

的格式

  

@＆＃34; [\＆＃34; registerDevice \＆＃34; {\＆＃34;类型\＆＃34;：\＆＃34; 7 \＆＃34; \＆＃34 ; pushBadge \＆＃34;：\＆＃34; 1 \＆＃34; \＆＃34; pushSound \＆＃34;：\＆＃34; 1 \＆＃34; \＆＃34;当使能\＆＃34;：\＆＃34; 1 \＆＃34; \＆＃34; deviceToken \＆＃34;：\＆＃34; e84ab955cd3b9af439f1567b9f80e70d52d3b0209151fe9b3392efc8af9f5e1f \＆＃34; \＆＃34; pushAlert \＆ ＃34;：\＆＃34; 1 \＆＃34;}]＆＃34 ;;
