Easy To Use Objective-C Library For Profiling The Performance Of A Specific Method
Sometimes when optimizing performance you may want to go beyond Xcode’s instruments and early last year I mentioned an example showing how to accurately time Objective-C blocks.
Here’s a new library called NanoProfiler that makes it very easy to time the performance of a specific method. With this library you don’t have to perform any modifications to the method, you simply set up the profiler to run a specific method, and get the result.
Here’s an example from the readme showing how to use NanoProfiler:
#import "NanoProfiler.h"
+(void) initialize {
AddProfiler([MyClass class], @selector(foo));
}
-(void) foo {
...
}
And you get a result like this:
*** Timer MyClass_foo stopped. runtime: 1.633041 milliseconds ***
You can find NanoProfiler on Github here.
An easy way to compare the efficiency of different pieces of code.
