Question

I am using to write some logs to write in locally when logs or data count above 50 i want to post the data to server. Then i write the next 50 logs values. My question is how to get the file count and how can i maintain this any one help me.

Answer 1

EDIT count records inside the File

Notice when addnew log to file add with \n line character so we can know how many logs added

NSString *str = [[NSString alloc]initWithContentsOfFile:yourFilePath encoding:NSUTF8StringEncoding error:nil];
NSArray *arrLogs = [str componentsSeparatedByString:@"\n"];
NSLog(@"Count of logs : %d",[arrLogs count]);

check this to how to get count of contents like this:

NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:dirPath error:nil];

Now filter contents like this:

NSPredicate *fltrtxt = [NSPredicate predicateWithFormat:@"self ENDSWITH '.txt'"];
NSArray *onlytxts = [dirContents filteredArrayUsingPredicate:fltrtxt];

Now count is:

if([onlytxts count] >= 50)
{
  //save new log to doc dir
  // post data to server;
  //after posting data u can do anything
}
