Custom NSLog for release and debugging, custom nslog debugging
Problem

• A large numberNSLogBut you want to cancel theseNSLog
• Is it often used during development?NSLog(@"%s", __FUNCTION__);

Solve the problem

• NewExtendNSLogClass, inherited fromNSObject
• InExtendNSLog.hDelete default code
• Add the following function declaration:

void ExtendNSLog(const char *file, int lineNumber, const char *functionName, NSString *format, ...);

• InExtendNSLog.mDelete default code
• Add the following code:

 1 void ExtendNSLog(const char *file, int lineNumber, const char *functionName, NSString *format, ...) { 2  3     va_list ap; 4  5     va_start(ap, format); 6  7     if (![format hasSuffix: @"\n"]) { 8         format = [format stringByAppendingString: @"\n"]; 9     }10 11     NSString *body = [[NSString alloc] initWithFormat:format arguments:ap];12 13     va_end(ap);14 15     NSString *fileName = [[NSString stringWithUTF8String:file] lastPathComponent];16     fprintf(stderr, "(%s) (%s:%d) %s",17             functionName,18             [fileName UTF8String],19             lineNumber,20             [body UTF8String]);21 }

• NewPrefixHeader.pchFile
• Enter the following content:

 1 #ifdef __OBJC__ 2  3 #import <UIKit/UIKit.h> 4 #import <Foundation/Foundation.h> 5  6 #import "ExtendNSLog.h" 7  8 #ifdef DEBUG 9 #define NSLog(args...) ExtendNSLog(__FILE__, __LINE__, __PRETTY_FUNCTION__, args);10 #else11 #define NSLog(x...)12 #endif13 14 #endif

• SelectProject->TARGETS->[ProjectName]->Build Settings
• Enter in the search boxprefix header
• InPrefix HeaderInput[ProjectName]/PrefixHeader.pch

As shown in

• Run the test, such as modifying the running mode.
