Explicit cast to int
显式转换为 int
NSUInteger foo = 23;
int bar = (int)foo;
Although
虽然
NSLog(@"%lu",foo);
will work OK on current builds of OSX. It's not safe, as NSUInteger is typedeffed as unsigned int on other builds. Such as iOS. The strict answer is to cast it first:
将在当前版本的 OSX 上正常工作。这是不安全的，因为 NSUInteger 在其他版本中被定义为 unsigned int。比如iOS。严格的回答是先投：
NSLog(@"%lu",(unsigned long)foo);

It's simple as this,
就这么简单，
NSUInteger uintV = 890;
int intVal = (int) uintV;
NSLog(@"the value is : %lu", (unsigned long)intVal);
this will print something like this,
the value is : 890
这将打印这样的东西，
值是：890
