I'm working on this objective c game app where the screen is populated with pictures of animals.
The problem is that the size and x/y of the animal is hard coded in the app and works with the iPad Air screen dimensions. My question is how can I scale it to show up in the same position and size on an iPhone 7 plus? Is there a formula to scale the size and x/y coordinates?
I looked for answers on stackoverflow with an answer saying to divide the dimensions but when i tried that the x/y coordinates were off.
Here is the code
-(void)viewDidLoad{
[super viewDidLoad];
NSString *sonidoPathBell1 = [[NSBundle mainBundle] pathForResource:#"bellTransition" ofType:#"aif"];
NSURL *sonidoUrlBell1 = [[NSURL alloc] initFileURLWithPath:sonidoPathBell1];
AudioServicesCreateSystemSoundID((CFURLRef)sonidoUrlBell1, &sonTrans);
btnAnimales = [[NSMutableArray alloc] initWithCapacity:0];
for(int i = 0; i < 20; i++){
OBShapedButton *tempbtn = [[OBShapedButton alloc] init];
[tempbtn setTag:i+1];
opcion = [[NSUserDefaults standardUserDefaults] integerForKey:[NSString stringWithFormat:#"bluebaymobAmazingMixAndMatchObjeto%i",i + 1]];
if (opcion == 0) {
[tempbtn setImage:[UIImage imageNamed:[NSString stringWithFormat:#"btnAni%i.png",i+1]] forState:UIControlStateNormal];
}else{
[tempbtn setImage:[UIImage imageNamed:[NSString stringWithFormat:#"btnAni%iColor.png",i+1]] forState:UIControlStateNormal];
}
[tempbtn addTarget:self action:#selector(startPuzzle:) forControlEvents:UIControlEventTouchUpInside];

I am making an app that has 2 UIImageViews but in each image view the image changes 3 times. How can I make it so that if image A collides with image B or C action happens but not with image A and so on. Here is the code for the image changing
ImageView Changing 1
This is a random change
Trap.center = CGPointMake(350,220);
Trap1 = rand() %3;
switch (Trap1) {
case 0:
Trap.image = [UIImage imageNamed:#"Image1.png"];
break;
case 1:
Trap.image = [UIImage imageNamed:#"Image2.png"];
break;
case 2:
Trap.image = [UIImage imageNamed:#"Image3.png"];
break;
default:
break;
}
ImageView Changing 2
This is set with a swipe and is copied for the other 2 changes.
-(IBAction)Change3:(id)sender{
UIImage *img = [UIImage imageNamed:#"Image4.tif"];
[Change3 setImage:img];
}
You can add a tag to your Trap object. Compare the tags and if they are different, do something.
Set tag:
switch (Trap1) {
case 0:
Trap.image = [UIImage imageNamed:#"Image1.png"];
Trap.tag = 1;
break;
case 1:
Trap.image = [UIImage imageNamed:#"Image2.png"];
Trap.tag = 2;
break;
case 2:
Trap.image = [UIImage imageNamed:#"Image3.png"];
Trap.tag = 3;
break;
default:
break;
}
Compare tags
If (trap1.tag != trap2.tag){
//Do something
}
I'm new to Xcode and i'm really stuck.
I have a UIProgressView which fills up with a UISwipeGestureRecognizer. I also have a switch statement. Now I want that only 7 ways to run (from the 242) while progressTrue is false. If progressTrue is true, so the UIProgressView is on 1.0, it should select new 7 cases randomly. Is something like that possible?
Thanks for any help!
-(void)vorgangDev {
int number = arc4random() % 242;
switch (number) {
case 0:
question.text = #"Anlieferung/anliefern";
answer.text = #"delivery, supply/deliver, supply";
answer.hidden = YES;
break;
case 1:
question.text = #"Artikel";
answer.text = #"article, item";
answer.hidden = YES;
break;
case 2:
question.text = #"Artikelanzahl";
answer.text = #"number of articles/ ~items";
answer.hidden = YES;
break;
//And so on...
}
Here I call vorgangDev.
if (progressTrue.progress == 1.0) {
// The UIProgressView is full
// if this is true do the question.
CABasicAnimation* fade = [CABasicAnimation animationWithKeyPath:#"backgroundColor"];
fade.fromValue = (id)[UIColor blackColor].CGColor;
fade.toValue = (id)[UIColor colorWithRed:50/255.0f green:109/255.0f blue:43/255.0f alpha:1.0f].CGColor;
[fade setDuration:1];
[self.view.layer addAnimation:fade forKey:#"fadeAnimation"];
progressTrue.progress = 0.0;
[self vorgangDev];
How can i change the Color of my Picker view depending on the background color of the TextField? e.g i have 2 text fields, The one is red and the other one is blue, If i clicked the red one the picker background is red also, And if i click the blue one the picker background will be blue also? im using this code for the text field to show the picker view.
int tag = [(UITextField*)sender tag];
self.myPicker.hidden = NO;
selectedTable = tag;
[sender resignFirstResponder];
float yy = 10;
switch (tag) {
case 0: yy = self.txtTgfeet.frame.origin.y + self.myPicker.frame.size.height;
break;
case 1: yy = self.txtTginches.frame.origin.y + self.myPicker.frame.size.height;
break;
case 2: yy = self.txtTgfraction.frame.origin.y + self.myPicker.frame.size.height;
break;
case 3: yy = self.txtBgfeet.frame.origin.y - self.myPicker.frame.size.height;
break;
case 4: yy = self.txtBginches.frame.origin.y - self.myPicker.frame.size.height;
break;
case 5: yy = self.txtBgfraction.frame.origin.y - self.myPicker.frame.size.height;
break;
case 6: yy = self.txtGravity.frame.origin.y - self.myPicker.frame.size.height;
break;
case 7: yy = self.txtBsw.frame.origin.y - self.myPicker.frame.size.height;
break;
case 8: yy = self.txtTemp.frame.origin.y - self.myPicker.frame.size.height;
break;
default:
break;
}
thank you!
use self.picker.backgroundColor = [UIColor redColor]; in textFieldDidBeginEditing: UITextFieldDelegate method and change color using by using tag property.
if(textField.tag == 1){
self.picker.backgroundColor = [UIColor redColor];
}
else if(textField.tag == 2){
self.picker.backgroundColor = [UIColor redColor];
}
else{
//use default value
}
Edit:
switch (tag) {
case 0: yy = self.txtTgfeet.frame.origin.y + self.myPicker.frame.size.height;
self.picker.backgroundColor = [UIColor redColor];
break;
case 1: yy = self.txtTginches.frame.origin.y + self.myPicker.frame.size.height;
self.picker.backgroundColor = [UIColor bluecolor];
break;
case 2: yy = self.txtTgfraction.frame.origin.y + self.myPicker.frame.size.height;
self.picker.backgroundColor = [UIColor greenColor];
break;
case 3: yy = self.txtBgfeet.frame.origin.y - self.myPicker.frame.size.height;
break;
case 4: yy = self.txtBginches.frame.origin.y - self.myPicker.frame.size.height;
break;
case 5: yy = self.txtBgfraction.frame.origin.y - self.myPicker.frame.size.height;
break;
case 6: yy = self.txtGravity.frame.origin.y - self.myPicker.frame.size.height;
break;
case 7: yy = self.txtBsw.frame.origin.y - self.myPicker.frame.size.height;
break;
case 8: yy = self.txtTemp.frame.origin.y - self.myPicker.frame.size.height;
break;
default:
break;
}
add different background colour for each case
I am trying to load an image and label corresponding to the table view row/cell selected by the user. The code appears in my DetailViewController implementation file as follows:
- (void)viewDidLoad
{
[super viewDidLoad];
//Create a couple of UIImages
UIImage *jenImage = [UIImage imageNamed:#"102_2262.jpg"];
UIImage *jen2Image = [UIImage imageNamed:#"102_2288.jpg"];
UIImage *paigeImage = [UIImage imageNamed:#"102_2332.jpg"];
UIImage *parkerImage = [UIImage imageNamed:#"102_2379.jpg"];
//Switch UIImages and UILabel based on characterNumber
switch (characterNumber) {
case 0:
characterName.text = #"Casual Jen";
characterPic.image = jenImage;
self.title = #"Casual Jen";
break;
case 1:
characterName.text = #"Dressed Up Jen";
characterPic.image = jen2Image;
self.title = #"Dressed Up Jen";
break;
case 2:
characterName.text = #"Paige";
characterPic.image = paigeImage;
self.title = #"Paige";
break;
case 3:
characterName.text = #"Parker";
characterPic.image = parkerImage;
self.title = #"Parker";
break;
default:
characterName.text = #"Parker";
characterPic.image = parkerImage;
self.title = #"Parker";
break;
}
}
The switch statement produces the error as described. I have searched for the solution here and elsewhere without success. Any help is greatly appreciated!
Make the data type of characterNumber as int.
