在AFHTTPSessionManager中自己主动添加一个单例就可以避免内存泄漏的问题
//用单例方法实力session避免内存泄漏
+ (AFHTTPSessionManager *)sharedHttpSessionManager {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
manager = [AFHTTPSessionManager manager];
manager.requestSerializer.timeoutInterval = 10.0;
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"text/json",@"text/javascript",@"text/html", nil];
});
return manager;
}
