自定义标签栏

以前写过一篇文章：自定义标签栏，这篇文章提供了另一种自定义标签栏的方式。
部分代码如下，具体的请参考附件。
- (void)addStandardTabView;
{
    JMTabView *tabView = [[[JMTabView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 60.)] autorelease];
    
    [tabView setDelegate:self];
    
    [tabView addTabItemWithTitle:@"One" icon:[UIImage imageNamed:@"icon1.png"]];
    [tabView addTabItemWithTitle:@"Two" icon:[UIImage imageNamed:@"icon2.png"]];
    [tabView addTabItemWithTitle:@"Three" icon:[UIImage imageNamed:@"icon3.png"]];
   
    //    You can run blocks by specifiying an executeBlock: paremeter
    //    #if NS_BLOCKS_AVAILABLE
    //    [tabView addTabItemWithTitle:@"One" icon:nil executeBlock:^{NSLog(@"abc");}];
    //    #endif
    
    [tabView setSelectedIndex:0];
    
    [self.view addSubview:tabView];
}

- (void)addCustomTabView;
{
    JMTabView *tabView = [[[JMTabView alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height - 60., self.view.bounds.size.width, 60.)] autorelease];
    tabView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleWidth;
    
    [tabView setDelegate:self];
        
    UIImage *standardIcon = [UIImage imageNamed:@"icon3.png"];
    UIImage *highlightedIcon = [UIImage imageNamed:@"icon2.png"];
    
    CustomTabItem *tabItem1 = [CustomTabItem tabItemWithTitle:@"One" icon:standardIcon alternateIcon:highlightedIcon];
    CustomTabItem *tabItem2 = [CustomTabItem tabItemWithTitle:@"Two" icon:standardIcon alternateIcon:highlightedIcon];
    CustomTabItem *tabItem3 = [CustomTabItem tabItemWithTitle:@"Three" icon:standardIcon alternateIcon:highlightedIcon];
    CustomTabItem *tabItem4 = [CustomTabItem tabItemWithTitle:@"Four" icon:standardIcon alternateIcon:highlightedIcon];
    CustomTabItem *tabItem5 = [CustomTabItem tabItemWithTitle:@"Five" icon:standardIcon alternateIcon:highlightedIcon];

    [tabView addTabItem:tabItem1];
    [tabView addTabItem:tabItem2];
    [tabView addTabItem:tabItem3];
    [tabView addTabItem:tabItem4];
    [tabView addTabItem:tabItem5];
    
    [tabView setSelectionView:[CustomSelectionView createSelectionView]];
    [tabView setItemSpacing:1.];
    [tabView setBackgroundLayer:[[[CustomBackgroundLayer alloc] init] autorelease]];
    
    [tabView setSelectedIndex:0];
    
    [self.view addSubview:tabView];
}
