UIToolBar的基本使用(三）

一個最基本的動態ToolBar的設定，並使用兩個Button來做移除及設定動態ToolBar的顯示
Xcode版本4.5 & IOS6

1. 開啓一個新的專案

2. 設定StoryBoard並加入一個Label及兩個Button

3. 設定dynamicToolBarViewController.h

@property (weak, nonatomic) IBOutlet UILabel *showLabel;
@property (weak, nonatomic) IBOutlet UIButton *showButton;
@property (weak, nonatomic) IBOutlet UIButton *delButton;

@property (nonatomic) UIToolbar *myToolBar;

@property (nonatomic) UIBarButtonItem *myBarItem1;
@property (nonatomic) UIBarButtonItem *myBarItem2;
@property (nonatomic) UIBarButtonItem *myBarItem3;
@property (nonatomic) UIBarButtonItem *myBarItem4;
@property (nonatomic) UIBarButtonItem *myBarItem5;

-(void)showText1 ;
-(void)showText2 ;
-(void)showText3 ;

4. 將控制碼加入到設定dynamicToolBarViewController. m

#import "dynamicToolBarViewController.h"

@interface dynamicToolBarViewController ()

@end

@implementation dynamicToolBarViewController

@synthesize showLabel;

@synthesize myToolBar;

@synthesize myBarItem1, myBarItem2, myBarItem3, myBarItem4, myBarItem5;


- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
   
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)showToolBar:(id)sender {

    [self setupMyToolBar];
   
    [self.view  addSubview:myToolBar];

}
- (IBAction)delToolBar:(id)sender {
   
    [self removeAllSubView];
}

-(void)setupMyToolBar
{
    myToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 704, 1024, 44.0)];
   
   
    //myBarItem1= [[UIBarButtonItem alloc] initWithCustomView:label];
    myBarItem1= [[UIBarButtonItem alloc]initWithTitle:@"Test1" style:UIBarButtonItemStylePlain target:self action:@selector(showText1)];
   
    myBarItem2= [[UIBarButtonItem alloc]initWithBarButtonSystemItem:(UIBarButtonSystemItemFixedSpace) target:nil action:nil];
   
   
    myBarItem3= [[UIBarButtonItem alloc]initWithTitle:@"Test2" style:UIBarButtonItemStyleBordered target:self action:@selector(showText2)];
   
    myBarItem4= [[UIBarButtonItem alloc]initWithBarButtonSystemItem:(UIBarButtonSystemItemFlexibleSpace) target:nil action:nil];
   
    myBarItem5= [[UIBarButtonItem alloc]initWithTitle:@"Test3" style:UIBarButtonItemStyleDone target:self action:@selector(showText3)];
   
    myBarItem2.width = 420;
   
    NSArray *toolbarItems = [[NSArray alloc] initWithObjects:myBarItem1,myBarItem2,myBarItem3,myBarItem4,myBarItem5,nil];
    myToolBar.items = toolbarItems;
   
}

- (void) removeAllSubView
{
    for(UIView *subview in [self.view subviews]) {
   
        if([subview isKindOfClass:[UIToolbar class]]) {
            [subview removeFromSuperview];
        }
       
    }
}


-(void)showText1
{
   
    NSString *text = @"測試一";
   
    showLabel.text = text;
   
}

-(void)showText2
{
   
    NSString *text = @"測試二";
   
    showLabel.text = text;
   
}

-(void)showText3
{
   
    NSString *text = @"測試三";
   
    showLabel.text = text;
   
}

@end
