Object-c中如何打印函数调用栈Object-c中如何打印函数调用栈

打印当前的函数名可以使用__PRETTY_FUNCTION__宏，或者封装一下:

#define NSSTRING_PRETTY_FUNCTION [NSString stringWithCString:__PRETTY_FUNCTION__ encoding:NSASCIIStringEncoding]

打印:

NSLog("Function Name:%@",NSSTRING_PRETTY_FUNCTION);

打印调用堆栈可以借助于: callStackSymbols

NSArray *syms = [NSThread  callStackSymbols]; 
if ([syms count] > 1) { 
    NSLog(@"<%@ %p> %@ - caller: %@ ", [self class], self, NSStringFromSelector(_cmd),[syms objectAtIndex:1]);
} else {
     NSLog(@"<%@ %p> %@", [self class], self, NSStringFromSelector(_cmd)); 
}
