如何在NSLog中打印int*&unsigned int*？

Question

如何打印int*(int指针)和unsigned int*在日志中使用NSLog？

- (int) doSomethingWith:(unsigned int)Msg withWparam:(unsigned int*)wParam withParameter:(int *) lParam
{
    NSLog(@"MSg:%d wParam:%u lParam:%u",Msg,wParam,lParam);
//not working
    return 1;
}

警告: Format specifies type 'unsigned int' but the argument has type 'unsigned int *'

Answer 1

使用%d了int.参数是指针,因此用于*访问指向的值.

NSLog(@"MSg:%d wParam:%u lParam:%d",Msg,*wParam,*lParam);

Answer 2

%@是为了对象.BOOL不是一个对象.你应该用%d.
在数据类型的基础上%@改变如下

For Strings you use %@
For int  you use %i
For float you use %f
For double you use %lf
