I have a really weird problem with UIImageView. I have an image (an RGB png) 45x45 pixels which I add to the view. I can see that image is blurred after added to the view. Here is the same image in the simulator (left) and in Xcode (right):
I have custom UIImageView class with this initWithImage code:
- (id) initWithImage:(UIImage*) image {
self = [super initWithImage:image];
self.frame = CGRectMake(0, 0, 45, 45);
self.contentMode = UIViewContentModeScaleAspectFit;
self.quantity = 1;
if (self) {
self.label = [[UITextField alloc]initWithFrame:CGRectMake(0,40,45,25)];
self.label.font = [UIFont systemFontOfSize:16];
self.label.borderStyle = UITextBorderStyleNone;
self.label.enabled = TRUE;
self.label.userInteractionEnabled = TRUE;
self.label.delegate = self;
self.label.keyboardType = UIKeyboardTypeNumbersAndPunctuation;
self.label.textAlignment = UITextAlignmentCenter;
}
self.userInteractionEnabled = TRUE;
// Prepare 3 buttons: count up, count down, and delete
self.deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.deleteButton.hidden = NO;
self.deleteButton.userInteractionEnabled = YES;
self.deleteButton.titleLabel.font = [UIFont systemFontOfSize:20];
self.deleteButton.titleLabel.textColor = [UIColor redColor];
[self.deleteButton setTitle:@"X" forState:UIControlStateNormal];
[self.deleteButton addTarget:self action:@selector(deleteIcon:) forControlEvents:UIControlEventTouchUpInside];
self.upCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.upCountButton.hidden = NO;
self.upCountButton.userInteractionEnabled = YES;
[self.upCountButton setTitle:@"+" forState:UIControlStateNormal];
[self.upCountButton addTarget:self action:@selector(addQuantity:) forControlEvents:UIControlEventTouchUpInside];
self.downCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.downCountButton.hidden = YES;
self.downCountButton.userInteractionEnabled = YES;
[self.downCountButton setTitle:@"-" forState:UIControlStateNormal];
[self.downCountButton addTarget:self action:@selector(removeQuantity:) forControlEvents:UIControlEventTouchUpInside];
return self;
}
I create it like this:
UIImage *desertIcon = [UIImage imageNamed:@"desert.png"];
IconObj *desertIconView = [[IconObj alloc] initWithImage:desertIcon];
desertIconView.center = CGPointMake(265,VERTICAL_POINT_ICON);
desertIconView.type = [IconObj TYPE_DESERT];
[self.view addSubview:desertIconView];
[desertIconView release];
Why would the displayed image be so than the one stored in a file?
