-(id) initWithPlayer:(VVPlayer *)aPlayer seatsNum:(int)seatsNum
{
if (self = [super init])
{
NSLog(@”\n Function: %s\n Pretty function: %s\n Line: %d\n File: %s\n Object: %@”,__func__, __PRETTY_FUNCTION__, __LINE__, __FILE__, aPlayer);
}
…
}
__func__ __PRETTY_FUNCTION__ __LINE__ __FILE__都是系统预留的定义词，简单易用
另外还有一些Core Foundation的方法可以从CFString的层级拿到一些有用的字符串，包括且不限于selector、class、protocol等
-(id) initWithPlayer:(VVPlayer *)aPlayer seatsNum:(int)seatsNum
{ if (self = [super init])
{
NSLog(@”Current selector: %@”, NSStringFromSelector(_cmd));
NSLog(@”Object class: %@”, NSStringFromClass([self class]));
NSLog(@”Filename: %@”, [[NSString stringWithUTF8String:__FILE__] lastPathComponent]);
}
…
}
