When you want to decode HTML characters within a string, just call the app like this.

MREntitiesConverter *converter = [[MREntitiesConverter alloc] init];
someStr = [converter convertEntiesInString:@"abcdefghiijXXXYZ"];
[converter release];

Easy enough?

UIAlertView *alert = [[UIAlertView alloc] init];
[alert setTitle:@"My Title"];
[alert setMessage:@"My message"];
[alert setDelegate:self];
[alert addButtonWithTitle:@"OK"];
[alert addButtonWithTitle:@"Cancel"];
[alert show];
[alert release];

With this, you can detect which button was pressed by handling the alertView message like this.

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
// Yes, do something
}
else if (buttonIndex == 1)
{
// No
}
}

And when I do this in my game, I’ll pause the game first and resume when player pushed on the button. This can be done easily via sharedDirector as well.

[[Director sharedDirector] pause]; //Pause your game
[[Director sharedDirector] resume]; //Resume your game

Hope you enjoy!

What you want to do is just creating your splash screen image in PNG format which have 320×480 resolution for portrait or 480×320 if your app is running on landscape orientation.

Then name it “Default.png”, please note that you have to name it “Default.png” not “default.png”. It’s case sensitive.

Then just put the file into your project and it’s DONE!

You will see your splash screen until your first view was loaded successfully.

Short & Sweet?

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

It just disables the Idle Timer of iPhone OS for my application.

Sweet!

When you run this code, it will capture the current screenshot and add into the Camera Roll.

It’s not yet included in the official SDK but you can get it run easily.

@interface UIApplication (Extended)
-(void) _writeApplicationSnapshot;
@end
[[UIApplication sharedApplication] _writeApplicationSnapshot];

Yo!
