개발 하다 보면 포매팅 스타일로 로그 찍는것도 여간 귀찮은 일이 아닌데..
오늘 좋은걸 하나 발견해서 바로 써먹었당;;
디따 간단함..
* 어떤 기능?
LOG_EXPR(self.window.screen);
self.window.screen = <UIScreen: 0x6d20780; bounds = {{0, 0}, {320, 480}}; mode = <UIScreenMode: 0x6d20c50; size = 320.000000 x 480.000000>>
LOG_EXPR(self.tabBarController.viewControllers);
self.tabBarController.viewControllers = (
“<UINavigationController: 0xcd02e00>”,
“<SavingsViewController: 0xcd05c40>”,
“<SettingsViewController: 0xcd05e90>”
)
Pretty straightforward, really. The biggest convenience so far is having the expression printed out, so you don’t have to write out a name redundantly in the format string (eg. NSLog(@"actionURL = %@", actionURL)). But LOG_EXPR really shows it’s worth when you start using scalar or struct expressions:
LOG_EXPR(self.window.windowLevel);
self.window.windowLevel = 0.000000
LOG_EXPR(self.window.frame.size);
self.window.frame.size = {320, 480}
* 어떻게 바로 써먹징?
Using LOG_EXPR() in Your Project
Download VTPG_Common.m and VTPG_Common.h from my github repository, and add them to your Xcode project.
Now just add the line #import "VTPG_Common.h" to your prefix file (named <ProjectName>_Prefix.pch by default), after the #ifdef __OBJC__, for example:
#ifdef __OBJC__
#import <Foundation/Foundation.h>
// maybe other files, depending on project template...
#import "VTPG_Common.h"
#endifNow LOG_EXPR() will work everywhere in your project.
