#import 

int main (int argc, const char * argv[])
{
    
    @autoreleasepool {
		NSFileManager *fm=[NSFileManager defaultManager];
		NSString *tempdir=NSTemporaryDirectory();
		
		NSLog(@"临时目录:%@",tempdir);
		
		NSString * currentPath=[fm currentDirectoryPath];
		NSLog(@"当前路径:%@",currentPath);
		
		NSString * filePath=[currentPath stringByAppendingPathComponent:@"main.m"];
		NSLog(@"当前文件路径:%@",filePath);
		
		NSString * extension=[filePath pathExtension];
		NSLog(@"当前文件扩展名:%@",extension);
		
		NSString * homeDir=NSHomeDirectory();
		NSLog(@"当前用户主目录:%@",homeDir);
		
		NSArray * components=[homeDir pathComponents];
		//用户主目录路径结构拆分
		for (NSString *path in components) {
			NSLog(@"%@",path);
		}
		
	}
    return 0;
