automatically Move imageView on screen like L shape iOS - ios

Question

I am trying to move image like L shape in my iOS app.
I have tried this code but it is moving image only in one line that I don't want.
- (void)startApp {
UIImageView *imageToMove =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"man.jpg"]];
imageToMove.frame = CGRectMake(10, 10, 100, 100);
[self.view addSubview:imageToMove];
// Move the image
[self moveImage:imageToMove
duration:1.0
curve:UIViewAnimationCurveLinear
x:70.0
y:70.0];
}
- (void)moveImage:(UIImageView *)image
duration:(NSTimeInterval)duration
curve:(int)curve
x:(CGFloat)x
y:(CGFloat)y {
// Setup the animation
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:duration];
[UIView setAnimationCurve:curve];
[UIView setAnimationBeginsFromCurrentState:YES];
// The transform matrix
CGAffineTransform transform = CGAffineTransformMakeTranslation(x, y);
image.transform = transform;
// Commit the changes
[UIView commitAnimations];
}

Answer 1

I would recommend something like this:
- (void)animateLikeL
{
[UIView animateWithDuration:1.5f
delay:0.0f
options:UIViewAnimationOptionCurveLinear
animations:^{
self.yourImage.transform = CGAffineTransformMakeTranslation(0.0f, 10.0f);
} completion:^(BOOL finished){
if(finished == NO)
{
return;
}
[UIView animateWithDuration:1.5f
delay:0.0f
options:UIViewAnimationOptionCurveLinear
animations:^{
self.yourImage.transform = CGAffineTransformMakeTranslation(10.0f, 10.0f);
} completion:^(BOOL finished){
if(finished == NO)
{
return;
}
self.yourImage.transform = CGAffineTransformIdentity;
[self animateLikeL];
}];
}];
}
Another attempt is to play arround with self.yourImage.center. Increase center.y to move the image down and then increase center.x to move it left. Hope this helps.

I did it like this: circle is a UIImage view in the interface builder size 70*70 and frame set at (10,10), then stick this code in:
- (void)viewDidAppear:(BOOL)animated {
[UIView animateWithDuration:1
delay:0
options:0
animations:^{
self.circle.frame = CGRectMake(10, 249, 70, 70);
}
completion:^(BOOL finished) {
[UIView animateWithDuration:1
delay:0
options:0
animations:^{
self.circle.frame = CGRectMake(150, 249, 70, 70);
}
completion:^(BOOL finished) {
NSLog(#"Complete");
}];
}];
}

Answer 3

I would just chain the animations.
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(x,0);
image.transform = transform;
} completion:^(BOOL finished) {
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(x,y);
image.transform = transform;
} completion:nil];
}];

This is what I have done......Thank you.
- (void)viewDidLoad
{
[super viewDidLoad];
[self startAppForFirstImg];
[self startAppForSecondImg];
}
//First Image coordinates.
- (void)startAppForFirstImg{
UIImageView *imageToMove =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"man.jpg"]];
imageToMove.frame = CGRectMake(180,280,100,100);
[self.view addSubview:imageToMove];
// Move the image
[self moveFirstImage:imageToMove duration:2.0
curve:UIViewAnimationCurveLinear x:0.0 y:-200.0];
}
-(void)moveFirstImage:(UIImageView *)image duration: (NSTimeInterval)duration
curve:(int)curve x:(CGFloat)x y:(CGFloat)y{
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(0,y);
image.transform = transform;
}
completion:^(BOOL finished) {
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(-70,-200);
image.transform = transform;
} completion:nil];
}];
}
//Second Image coordinates.
- (void)startAppForSecondImg{
UIImageView *imageToMove =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"man.jpg"]];
imageToMove.frame = CGRectMake(20,20,100,100);
[self.view addSubview:imageToMove];
// Move the image
[self moveSecondImage:imageToMove duration:2.0
curve:UIViewAnimationCurveLinear x:0.0 y:290.0];
}
-(void)moveSecondImage:(UIImageView *)image duration: (NSTimeInterval)duration
curve:(int)curve x:(CGFloat)x y:(CGFloat)y{
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(0,y);
image.transform = transform;
}
completion:^(BOOL finished) {
[UIView animateWithDuration:duration/2 delay:0 options:curve animations:^{
CGAffineTransform transform = CGAffineTransformMakeTranslation(90,290);
image.transform = transform;
} completion:nil];
}];
}
