Is there a way to fast forward an audio file by x2, x4 etc by the use of a button? If not, do you have any idea how this would be possible?
NSTimeInterval *timeIntervel = [yourPlayer currentTime];
timeIntervel = timeIntervel + timeToForword;
[yourPlayer setCurrentTime:timeIntervel];
[yourPlayer play];

how can i make a counter to be used in addressing issues. (sample output: Issue 001). I need to save the current value of the counter(001) in the device so that when there is another issue to be sent by the app i will increment the current value of the counter.
Don't know where to start.
thanks in advance.
You can use the NSUserDefaults
get and store the value
NSInteger count = [[[NSUserDefaults standardUserDefaults] valueForKey:#"count"] integerValue];
count++;
[[NSUserDefaults standardUserDefaults]setValue:[NSNumber numberWithInteger:count] forKey:#"count"];

Is there a way in rails via some mapping API/gem where I can define map areas/map zones (with polygon bounds) and detect if an address falls within a particular zone/area.
This is easily done with geokit.
First construct a polygon from LatLng:
polygon = Geokit::Polygon.new([
Geokit::LatLng.new(0,0),
Geokit::LatLng.new(10,0),
Geokit::LatLng.new(10,10),
Geokit::LatLng.new(20,10),
Geokit::LatLng.new(20,0),
Geokit::LatLng.new(30,0),
Geokit::LatLng.new(30,20),
Geokit::LatLng.new(0,20)
])
Then you can test if the polygon contains a LatLng:
point = Geokit::LatLng.new(5,5)
polygon.contains?(point) # => true

I wonder How Make the players waiting؟ like candy crush When the player loses all points of Health He must wait some time
How i can do this?
Thanks
Create a date object when the player loses
NSDate *stopTime = [NSDate dateWithTimeIntervalSinceNow:0];
and store that date in NSUserDefaults. To check if the user has waited long enough, read the date from NSUserDefaults, and compute the delta between the stop time and the current time. For example, if the user needs to wait 15 minutes, then
NSTimeInterval delta = [stopTime timeIntervalSinceNow];
delta = -delta;
if ( delta > 15 * 60 )
// OK to play
else
// still waiting

Is it possible to limit the size of attachment that can be send or received in qmail. Its to stop mail forwardings with large sizes amoung employees.
The maximum message size for emails in a qmail-installation is normally defined by the following file:
./qmail/control/databytes
The size is defined in bytes. Example:
50000000
Limit would be: 50000000Bytes = 48,828Kb = 47,68MB
