# iOS

### 简介

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

*`MiniWallet`*可以实现对于特定操作，第三方App不需要拉起钱包，直接在应用内部完成，体验更为流畅。

### 初始化

```
[TPApi registerAppID:@"tpsdk"];
[TPApi setSeed:@"xxxx" error:nil];
[TPApi setBlockChain:TPBlockChainTypeEOSMainNet nodeUrl:@"http://eosinfo.mytokenpocket.vip" plugNodeUrl:@"http://eosinfo.mytokenpocket.vip"];
```

### Auth

```
TPAuthObj *auth = [TPAuthObj new];
auth.dappName = @"xxx";
auth.dappIcon = @"https:.../xx.png";
auth.account = "xxxx";
auth.perm = "xxxx";
auth.selectAll = NO;
auth.actions = [linkActions];
[TPApi sendObj:auth resultHandle:^(TPReqType type,NSError *error) {
    // ...        
}];


/// Response ↓
TPRespObj.data
{
    ...,
    "ref" : "TokenPocket",
    "publickey" : "EOS5AvWThdghtNngWP4UcNi9DL6kF7Mnv2ccO",
    "sign" : "SIG_K1_JyCJtV9vqwxtyEt68UhUibkg1CmRjxtG6zkZwE...",
    "timestamp" : "1554266633",
}
```

### 发起交易

* 构建数据，将操作的*action*中的*permission*字段值替换成调用auth传递的perm字段。
* 调&#x7528;*`TPApi perm:(NSString *)perm isLinkActions:(NSArray<TPLinkAction *> *)actions account:(NSString *)account completion:(void (^)(BOOL permExisted,BOOL linked,NSError *error))completion`*&#x68C0;查action绑定状态。
* 如果第二步绑定成功，则直接调用'Auth'。
* 如果第二步绑定失败，则需要开发者将permission字段替换成active或者owner,以便拉起钱包执行操作。

### 方法说明

#### **修改***`seed`*

```
+ (void)resetSeed:(NSString *)seed newSeed:(NSString *)newSeed error:(NSError **)error;
```

#### **获取已授权账号信息**

```
+ (NSArray<NSString *> *)getAccounts;
```

#### **检查权限是否存在**

```
+ (void)isPermExist:(NSString *)perm account:(NSString *)account completion:(void (^)(BOOL exist,NSError *error))completion;
```

#### **检查权限是否link到***`action`*

```
+ (void)perm:(NSString *)perm isLinkActions:(NSArray<TPLinkAction *> *)actions account:(NSString *)account completion:(void (^)(BOOL permExisted,BOOL linked,NSError *error))completion;
```

#### **清除本地授权**

```
+ (BOOL)clearAuth:(NSString *)account;
```
