YourViewontroller.h
UIView *view_navigation;
viewcontroller.m
- (void)viewDidLoad
{
view_navigation = [[UIView alloc]initWithFrame:CGRectMake(200, 5, 100, 40)];
view_navigation.backgroundColor = [UIColor clearColor];
UIButton *add_button = [UIButton buttonWithType:UIButtonTypeCustom];
[add_button setBackgroundImage:[UIImage imageNamed:#"Add-icon.png"] forState:UIControlStateNormal];
[add_button addTarget:self action:#selector(Add_Student:) forControlEvents:UIControlEventTouchUpInside];
[add_button.imageView setContentMode:UIViewContentModeScaleToFill];
[add_button setFrame:CGRectMake(0, 8, 25, 25)];
[view_navigation addSubview:add_button];
UIButton *Remove_button = [UIButton buttonWithType:UIButtonTypeCustom];
[Remove_button setBackgroundImage:[UIImage imageNamed:#"Delete_icon.jpeg"] forState:UIControlStateNormal];
[Remove_button addTarget:self action:#selector(Remove_Student:) forControlEvents:UIControlEventTouchUpInside];
[Remove_button.imageView setContentMode:UIViewContentModeScaleToFill];
[Remove_button setFrame:CGRectMake(40, 8, 25, 25)];
[view_navigation addSubview:Remove_button];
UIButton *Edit_button = [UIButton buttonWithType:UIButtonTypeCustom];
[Edit_button setBackgroundImage:[UIImage imageNamed:#"Edit_icon.jpeg"] forState:UIControlStateNormal];
[Edit_button addTarget:self action:#selector(Edit_Student:) forControlEvents:UIControlEventTouchUpInside];
[Edit_button.imageView setContentMode:UIViewContentModeScaleToFill];
[Edit_button setFrame:CGRectMake(80, 8, 25, 25)];
[view_navigation addSubview:Edit_button];
[self.navigationController.navigationBar addSubview:view_navigation];
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)viewWillDisappear:(BOOL)animated
{
[view_navigation removeFromSuperview];
[super viewWillDisappear:animated];
}
