Implicit conversion loses integer precision: 'long long' to 'NSInteger' (aka 'int')

ios, ios5, long-integer, nsuinteger, xcode4.2

Solution

It's really just a cast, with some range checking:

const long long expectedContentLength = response.expectedContentLength;
NSUInteger expectedSize = 0;

if (NSURLResponseUnknownLength == expectedContentLength) {
    assert(0 && "length not known - do something");
    return errval;
}
else if (expectedContentLength < 0) {
    assert(0 && "too little");
    return errval;
}
else if (expectedContentLength > NSUIntegerMax) {
    assert(0 && "too much");
    return errval;
}

// expectedContentLength can be represented as NSUInteger, so cast it:
expectedSize = (NSUInteger)expectedContentLength;

Problem

I am trying to assign a variable with type 'long long' to a type NSUInteger, What is the correct way to do that? my code line: ``` expectedSize = response.expectedContentLength > 0 ? response.expectedContentLength : 0; ``` where `expectedSize` is of type NSUInteger and return type of `response.expectedContentLength` is of type '`long long`'. The variable `response` is of type `NSURLResponse`. The compile error shown is: Semantic Issue: Implicit conversion loses integer precision: 'long long' to 'NSUInteger' (aka 'unsigned int')
