Objective-C实现计算你写了多少行代码

#import <Foundation/Foundation.h>

NSInteger codeLineCount(NSString *path)

{

//1.获取文件管理者，这是一个单例

NSFileManager *manage = [NSFileManager defaultManager];

//2.判断文件夹or文件

BOOL dir = NO;

BOOL exist = [manage fileExistsAtPath:path isDirectory:&dir];

if (!exist) return 0;

if (dir) {

NSArray *arr = [manage contentsOfDirectoryAtPath:path error:nil];

NSInteger count = 0;

for (NSString *str in arr) {

NSString *fullPath = [NSString stringWithFormat:@"%@/%@", path, str];

count += codeLineCount(fullPath);

}

return count;

}else{

NSString *content =  [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

NSArray *arr = [content componentsSeparatedByString:@"\n"];

return arr.count;

}

}

int main(int argc, const char * argv[]) {

@autoreleasepool {

#warning 这里改成你想要计算的文件夹活着文件

NSInteger count = codeLineCount(@"/Users/hj/work/hjhj");

NSLog(@"%ld",count);

}

return 0;

}
