将NSInteger转换为NSUInteger? [英] Convert NSInteger to NSUInteger?

问题描述

我正在尝试将NSInteger转换为NSUInteger，我在Google上进行了搜索，但没有找到真正的答案.我该怎么办?

I am trying to convert a NSInteger to a NSUInteger and I googled it and found no real answer. How would I do this?

推荐答案

NSInteger和NSUInteger只是原始整数类型的typedef:

NSInteger and NSUInteger are just typedefs for primitive integer types:

#if __LP64__ || NS_BUILD_32_LIKE_64
  typedef long NSInteger;
  typedef unsigned long NSUInteger;
#else
  typedef int NSInteger;
  typedef unsigned int NSUInteger;
#endif

因此，您无需在它们之间转换".一个简单的转换就足够了.喜欢:

As such, you don't need to "convert" between them. A simple cast should be sufficient. Like:

NSInteger myInt = 0;
NSUInteger unsignedInt = (NSUInteger)myInt;
