AFURLConnectionOperation.m Implicit conversion loses integer precision: 'int64_t' (aka 'long long') to 'NSInteger' (aka 'int')

问题

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') 

Is this important?

回答1:

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.

See a this: ConvertingYourAppto-64Bit

if you don't want more warning. you can must change to architecture in Xcode 5.1

回答2:

You can make the following change manually until the next CocoaPod release (the change is already in GitHub).

change:

[decoder decodeInt64ForKey:NSStringFromSelector(@selector(totalBytesRead))];

to:

[decoder decodeIntegerForKey:NSStringFromSelector(@selector(totalBytesRead))];

AFNetworking v2.2.1 fixes this issue.

回答4:

you probably select as simulator : iPhone Retina (4-inch 64-bit). Try with the 32 bits
