    <p>i wrote the following code:</p> <pre><code>-(void)viewDidLoad{ JumpVelocity = 10; aStandRightArray = [[NSArray alloc] initWithObjects:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"aStandR1" ofType:@"png"]], [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"aStandR2" ofType:@"png"]], [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"aStandR3" ofType:@"png"]], [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"aStandR2" ofType:@"png"]], nil]; aJumpRightArray = [[NSArray alloc] initWithObjects:[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"aJumpR" ofType:@"png"]], nil]; aStandRight = [[UIImageView alloc] initWithFrame:CGRectMake(0, 242, 55, 65)]; aStandRight.animationImages = aStandRightArray; aStandRight.animationDuration = 0.5; [self.view addSubview:aStandRight]; aJumpRight = [[UIImageView alloc] initWithFrame:CGRectMake(0, 234, 69, 65)]; aJumpRight.animationImages = aJumpRightArray; [self.view addSubview:aJumpRight];} -(IBAction)buttonJumpRight:(id)sender{ [aStandRight stopAnimating]; [aStandRight removeFromSuperview]; [aJumpRight startAnimating]; jumpTimer = [NSTimer scheduledTimerWithTimeInterval:0.02 target:self selector:@selector(playerJumpRight) userInfo:nil repeats:YES];} -(void)playerJumpRight{ [aJumpRight removeFromSuperview]; aJumpRight.center = CGPointMake(aJumpRight.center.x + JumpVelocity, 234); [self.view addSubview:aJumpRight]; if(aJumpRight.center.x &gt;= 84.0) { [jumpTimer invalidate]; jumpTimer = nil; [aJumpRight stopAnimating]; aStandRight.center = CGPointMake(84, 242); [aStandRight startAnimating]; [self.view addSubview:aStandRight]; } </code></pre> <p>}</p> <p>basically what i am trying to do here is load up a standing animation, then when the user presses the buttonJumpRight button i stop then unload the standing animation. after that i load up the jump animation and begin to move it across the screen with the playerJumpRight function.</p> <p>everything seems to work fine with two exception:</p> <ol> <li><p>the jump animation moves like expected along the x axis but for some reason does not keep its original y position which in the code above is "234".</p></li> <li><p>when the jump animation x position meets the requirements for the if statement everything works like expected newly created position for the standing animation is way off of the desire position of (84, 242).</p></li> </ol> <p>i been searching for quite some time, trying out many different possible solutions but fail at every try. please excused my newbieism as i just start coding for ios/objective c.</p> <p>i greatly appreciate any help you can offer. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
