### Import SDK

GitHub: [***TP iOS SDK***](https://github.com/TP-Lab/Mobile-SDK/tree/master/iOS%20SDK)

Download the *`TPSDK.zip`* in the [***GitHub repository***](https://github.com/TP-Lab/Mobile-SDK/tree/master/iOS%20SDK). Unzip *`TPSDK.zip`* and add it into your Xcode project;

1. Set your *URL scheme*: *`Project`*->*`TARGETS`*->*`info`*->*`URL Types`*->*`Add URL scheme`*;
2. Add an item *`LSApplicationQueriesSchemes`* in the *`info.plist`*，value with *`tpoutside`;*

### **Initializing**

* **Add related .h file in** *`AppDelegate.m`*

```
#import <TPSDK/TPSDK.h>
```

* **Register your app&#x20;*****scheme*****&#x20;in method** *`application:didFinishLaunchingWithOptions:`*

```
[TPApi registerAppID:@"demoapp"];
```

* **Handle&#x20;*****callback*****&#x20;in method** *`application:openURL:`*

```
[TPApi handleURL:url options:options result:^(TPRespObj *respObj) {
    respObj.result;     // TPRespResultCanceled = 0,TPRespResultSuccess, TPRespResultFailure,
    respObj.message;    // Result message
    respObj.data;       // Json details
    /* Json details:
    {
        "result" : 1,
        "action" : "sign",
        "version" : "1.0",
        "protocol" : "TPProtocol",
        "ref" : "TokenPocket",
        "wallet" : "xxx...xxx",       // When success
        "publickey" : "xxx...xxx",    // When success
        "permissions" : [             // When success; for eosio/iost networks.
            "active",
            "owner"
        ],
        ...,
    }
    */
}];
```
