bar button item add toolbar programmatically

问题

I want to add button instead of bar button item into toolbar programmatically. I select it because button has image infodark defaut.

so how is this done programmatically?

回答1:

UIImage* image = [UIImage imageNamed:defaultImage];
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* button = [[UIButton alloc] initWithFrame:frame];
[button setTitle:@"Display" forState:UIControlStateNormal & UIControlStateHighlighted];
[button setImage:image forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:selectedImage] forState:UIControlStateSelected];
[button addTarget:self action:@selector(button_Clicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];

回答2:

To add this button in UIToolbar you need this code. first you can initialize UIToolbar after that

NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:4];

[buttons addObject: barButtonItem];
[buttons addObject: btnFav];
[buttons addObject: btnGeneralPopOverController];
[buttons addObject: showInfo];   

[mytoolbar setItems:buttons animated:NO];
