I have a UIView
with an alpha of .5
I have added a subview with an alpha of 1.
The subview seems to inherit the alpha value of the parent. Is there a way to make the subview more opaque than its parent view?
code looks like this:
CGRect promptFrame = CGRectMake(55, 80, 180, 50);
UIView *inputPrompt = [[UIView alloc] initWithFrame: promptFrame];
[inputPrompt setBackgroundColor: [UIColor darkGrayColor]];
[inputPrompt setAlpha: .5];
inputPrompt.layer.cornerRadius = 8;
inputPrompt.layer.masksToBounds = YES;
CGRect fileTextFieldFrame = CGRectMake(10, 15, 150, 25);
UITextField *filePrompt = [[UITextField alloc] initWithFrame: fileTextFieldFrame];
[filePrompt setBorderStyle:UITextBorderStyleRoundedRect];
[filePrompt setClearButtonMode:UITextFieldViewModeWhileEditing];
[filePrompt setBackgroundColor: [UIColor whiteColor]];
[filePrompt setAlpha: 1];
The result looks like this:
I would like to be able to see the button below the gray UIView
but not below the white UITextField
. How do I do this?
Set the inputPrompt
's background color's alpha not its alpha directly.
[inputPrompt setBackgroundColor:[[UIColor darkGrayColor] colorWithAlphaComponent:0.5]];
//[inputPrompt setAlpha: .5];
