    UIBarButtonItem *temp = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:@"BlueMarbleDrop"] forState:UIControlStateNormal];
    button.frame=CGRectMake(0.0, 0.0, 60.0, 30.0);
    [button addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem* stopBtn = [[UIBarButtonItem alloc] initWithCustomView:button];

    [self.toolBar setItems:[NSArray arrayWithObjects:temp,stopBtn,temp, nil]];

the output look like enter image description here
