一、內(nèi)購支付的流程
用戶選擇需要訂閱的商品芬位，發(fā)起購買无拗，支付完成，校驗票據(jù)晶衷。
具體步驟：
1.新建內(nèi)購相關(guān)文件

注意：
1.之所以吧SKPaymentTransactionStateRestored這個狀態(tài)放在else進(jìn)行操作锹漱，是為了避免校驗票據(jù)的時候會走多次的問題箭养。可以把
case SKPaymentTransactionStateRestored: {
//已經(jīng)購買過該商品
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
break;
這句話放到SKPaymentTransactionStateDeferred之后進(jìn)行打印操作試試哥牍。避免服務(wù)器內(nèi)存瞬間暴漲導(dǎo)致崩潰毕泌。
2.校驗票據(jù)接口里面用到的通知kPostNotification是為了操作一些業(yè)務(wù)。比如刷新用戶VIP狀態(tài)嗅辣、購買成功后當(dāng)前訂閱界面關(guān)閉掉等業(yè)務(wù)撼泛，其他自行操作。
3.isShowLoading是為了是不是顯示加載框澡谭。避免用戶亂操作愿题。
4.device_id使用下面方法獲取：
- (NSString *)device_id {
if (!_device_id) {
NSString *locallyID = [kUserDefaults valueForKey:kDeviceKey];
BOOL locally = [NSString isBlank:locallyID];
NSString *keyChainID = [JScreenUnit readData:deviceIDChain];
BOOL keyChain = [NSString isBlank:keyChainID];
if (locally && keyChain) {
CFUUIDRef puuid = CFUUIDCreate(nil);
CFStringRef uuidString = CFUUIDCreateString(nil, puuid);
NSString *result = (NSString *)CFBridgingRelease(CFStringCreateCopy(NULL, uuidString));
NSMutableString *tmpResult = result.mutableCopy;
_device_id = tmpResult;
} else if (!locally) {
_device_id = locallyID;
} else if (!keyChain) {
_device_id = keyChainID;
}
if (locally) {
[kUserDefaults setValue:_device_id forKey:kDeviceKey];
[kUserDefaults synchronize];
}
if (keyChain) {
[JScreenUnit saveData:_device_id withIdentifier:deviceIDChain];
}
}
return _device_id;
}
/*!
保存數(shù)據(jù)
*/
+ (BOOL)saveData:(id)data withIdentifier:(NSString*)identifier {
// 獲取存儲的數(shù)據(jù)的條件
NSMutableDictionary * saveQueryMutableDictionary = [self keyChainIdentifier:identifier];
// 刪除舊的數(shù)據(jù)
SecItemDelete((CFDictionaryRef)saveQueryMutableDictionary);
// 設(shè)置新的數(shù)據(jù)
[saveQueryMutableDictionary setObject:[NSKeyedArchiver archivedDataWithRootObject:data] forKey:(id)kSecValueData];
// 添加數(shù)據(jù)
OSStatus saveState = SecItemAdd((CFDictionaryRef)saveQueryMutableDictionary, nil);
// 釋放對象
saveQueryMutableDictionary = nil ;
// 判斷是否存儲成功
if (saveState == errSecSuccess) {
return YES;
}
return NO;
}
/*!
讀取數(shù)據(jù)
*/
+ (id)readData:(NSString*)identifier {
id idObject = nil ;
// 通過標(biāo)記獲取數(shù)據(jù)查詢條件
NSMutableDictionary * keyChainReadQueryMutableDictionary = [self keyChainIdentifier:identifier];
// 這是獲取數(shù)據(jù)的時，必須提供的兩個屬性
// TODO: 查詢結(jié)果返回到 kSecValueData
[keyChainReadQueryMutableDictionary setObject:(id)kCFBooleanTrue forKey:(id)kSecReturnData];
// TODO: 只返回搜索到的第一條數(shù)據(jù)
[keyChainReadQueryMutableDictionary setObject:(id)kSecMatchLimitOne forKey:(id)kSecMatchLimit];
// 創(chuàng)建一個數(shù)據(jù)對象
CFDataRef keyChainData = nil ;
//NSError *error;
// 通過條件查詢數(shù)據(jù)
if (SecItemCopyMatching((CFDictionaryRef)keyChainReadQueryMutableDictionary , (CFTypeRef *)&keyChainData) == noErr){
@try {
idObject = [NSKeyedUnarchiver unarchiveObjectWithData:(__bridge NSData *)(keyChainData)];
} @catch (NSException * exception){
NSLog(@"Unarchive of search data where %@ failed of %@ ",identifier,exception);
}
}
if (keyChainData) {
CFRelease(keyChainData);
}
// 釋放對象
keyChainReadQueryMutableDictionary = nil;
// 返回數(shù)據(jù)
return idObject ;
}
5.使用：
#pragma mark - 確認(rèn)
-(void)comeButtonClick{
if (!self.chooseBtn.selected) {
[SVProgressHUD showInfoWithStatus:@"請閱讀并同意《隱私協(xié)議》和《服務(wù)條款》"];
return;
}
//購買
[[JPurchaseManager shareManager] purchaseWithProductIdentifier:[self.model.products firstObject].pID];
}
7.恢復(fù)購買
//恢復(fù)購買
- (void)reBuyClick {
[[JPurchaseManager shareManager] resumePurchase];
}
6.記得釋放。
