问题解答

在 body 里的字符串中添加 \n 达到换行的效果 ，代码示例如下 ：

{
    "aps": {
        "alert": {
            "title": "title",
            "subtitle": "subtitle",
            "body": "This is some fancy message. \nThis is some fancy message. \nThis is some fancy message. \nThis is some fancy message. "
        },
        "badge": 1,
        "sound": "default",
        "category": "test_category",
        "mutable-content": 1
    },
    "key1":"value1",
    "key2":"value2"
}
