本文介绍了AFURLConnectionOperation.m隐式转换失去整数精度:'int64_t'(又名'long long')到'NSInteger'(又名'int')的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在 Xcode 5.1
中收到警告,如下所述
I got a warning in Xcode 5.1
as stated below
AFNetworking 2.2.0: AFURLConnectionOperation.m Implicit conversion loses integer precision: 'int64_t' (aka 'long long') to 'NSInteger' (aka 'int')
这很重要吗?
推荐答案
这意味着arm64架构 int64_t
范围是 -9,223,372,036,854,775,808到9,223,372,036,854,775,807
但是 int
范围是 -2,147,483,648到2,147,483,647
。所以编译器说损失价值。
This mean is arm64 architecture int64_t
range is -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
but int
range is -2,147,483,648 to 2,147,483,647
. so compiler say to Loss of value.
看到这个:
如果你不想要更多警告。您必须在Xcode 5.1中更改为架构
if you don't want more warning. you can must change to architecture in Xcode 5.1
