Question

I created view-based application.
I have got a sampleGameViewContrioller.xib, which contains main View, and child View, which connected with class Behavior.

SampleViewController.xib:

• View
  • View <- Behavior

In sampleViewContoller.m I create instance of the class Behavior:

Behavior *b = [[Behavior alloc] initilizeWithType:@"type" position:rect mapArray:arrMap];

Behavior.m:

 -(id) initilizeWithType:(NSString *)type position:(CGRect) pos mapArray:(NSMutableArray *) mapArr {

 self = [super initWithFrame:CGRectMake(0, 0, 1024, 570)];
 if (self != nil) {
 if ([type isEqualToString:@"type"]) {
 arrMap = mapArr;
 self.rectForDraw = pos;
 self.file = [[NSString alloc]initWithString:@"girl.png"];
 UIImageView *imgg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"girl.png"]];
 imgg.frame = rect;
 [self addSubview:imgg];
 timer = [NSTimer scheduledTimerWithTimeInterval:0.015 target:self selector:@selector(moving:) userInfo:nil repeats:YES];
 }
 }
 return self;} 

But it doesn’t work. Image doesn’t add to my View.

if I add imageView in -(void)drawRect:(CGRect) rect, it’s working:

- (void)drawRect:(CGRect)rect {
 self.img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"girl.png"]];
 self.img.frame = CGRectMake(100, 100, 100, 100);
 [self addSubview:self.img]; }

But i should send parameters of drawing in class Behavior through constructor. How to add imageView without method drawRect, with my constructor?

sorry for my English 🙂

Answer 1

If u want to add an image view over simple UIView then just do [self.view addSubview:imageview]; If you are getting that Image from Behaviour class method then return UIImageView from that method and the add it to your view
Try this:

Behavior *b = [[Behavior alloc] init];

Then write one method in Behaviour class

-(UIImageView*) initilizeWithType:(NSString *)type position:(CGRect) pos mapArray:(NSMutableArray *) mapArr {
// Your Logic

return  imgView;  //UIImageView object
} 

Then call this method in your viewcontroller as

UIImageView *imgView=[b initilizeWithType:@"YOUR STRING" position:YOUR RECT pos mapArray:YOUR ARRAY ];
