IOS用NSLog做 debug調試

-(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__都是系統預留的定義詞，簡單易用


另外還有一些Core Foundation的方法可以從CFString的層級拿到一些有用的字串，包括且不限於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]);  }…}
