细心的你是否也发现了 AFN 的内存泄漏的问题了呢.
解决方法
+ (AFHTTPSessionManager *)sharedHTTPSession{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
manager = [AFHTTPSessionManager manager];
manager.requestSerializer.timeoutInterval = 30;
[manager.requestSerializer setValue:@"XMLHttpRequest" forHTTPHeaderField:@"X-Requested-With"];
});
return manager;
}
+ (AFURLSessionManager *)sharedURLSession{
static dispatch_once_t onceToken2;
dispatch_once(&onceToken2, ^{
urlsession = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
});
return urlsession;
}将有问题的语句全部替换成单例后，再用 instruments 检查，再也没有出现泄漏的红叉了。O(∩_∩)O 哈哈~
