I have two questions about the UIToolbar:
1: I have read numerous Stackoverflow answers on how to use buttons with custom images (colored) in a UIToolbar. I have tried to put a view (hack) on top of the UIToolbar and put the buttons with the images in it, but failed. Right now I am stuck. How can you accomplish this?
2: Is there a way to have many buttons in "pressed" state simultaneously? The function I want to accomplish is different buttons with different kind kinds of sorting.
Ok the answer solved itself... here it is:
Can I have a UIBarButtonItem with a colored image?
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
toolbar = [[UIToolbar alloc] init];
toolbar.barStyle = UIBarStyleDefault;
//Set the toolbar to fit the width of the app.
[toolbar sizeToFit];
//Calculate the height of the toolbar
CGFloat toolbarHeight = [toolbar frame].size.height;
//Get the bounds of the parent view
CGRect rootViewBounds = self.parentViewController.view.bounds;
//Get the height of the parent view.
CGFloat rootViewHeight = CGRectGetHeight(rootViewBounds);
//Get the width of the parent view,
CGFloat rootViewWidth = CGRectGetWidth(rootViewBounds);
//Create a rectangle for the toolbar
CGRect rectArea = CGRectMake(0, rootViewHeight - toolbarHeight, rootViewWidth, toolbarHeight);
//Reposition and resize the receiver
[toolbar setFrame:rectArea];
//Create a button
UIImage *image = [UIImage imageNamed:@"colorImage.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:@selector(myAction) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
[toolbar setItems:[NSArray arrayWithObjects:barButtonItem,nil]];
//Add the toolbar as a subview to the navigation controller.
[self.navigationController.view addSubview:toolbar];
}
-(void)myAction{
NSLog(@"jippiii");
}
