獲取app安裝時間
可以變相獲取文件創(chuàng)建時間
NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSDictionary *FileInfo = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil];//獲取文件信息
id firstData = [FileInfo objectForKey:NSFileCreationDate];//獲取文件創(chuàng)建
NSLog(@"%@",firstData);
待真機(jī)檢測!!!!!!!!!!!!!!!!!!!!!!!!
