關於UITabbar 圖片

屬於 Bar  的有
- Navigation bars
- Toolbars
- Tabbars

Style/Image 可透過

- (id)initWithTitle:(NSString *)title image:(UIImage *)image tag:(NSInteger)tag; - (id)initWithTabBarSystemItem:(UITabBarSystemItem)systemItem tag:(NSInteger)tag;

Style

typedef enum {     UITabBarSystemItemMore,     UITabBarSystemItemFavorites,     UITabBarSystemItemFeatured,     UITabBarSystemItemTopRated,     UITabBarSystemItemRecents,     UITabBarSystemItemContacts,     UITabBarSystemItemHistory,     UITabBarSystemItemBookmarks,     UITabBarSystemItemSearch,     UITabBarSystemItemDownloads,     UITabBarSystemItemMostRecent,     UITabBarSystemItemMostViewed, } UITabBarSystemItem;

TabBar icon 大小
32 x 32 png 背景為透明。

TabBar icon 作圖，參考

tabbaritem的png無法顯示

顯示圖片設定，實際顯示的圖片會便

UIImage* aImage = [UIImage imageNamed:@"favorites.png"]; [self.tabBarItem setImage:aImage];

內建直接設定 badge，後面帶入 NSString

[self.tabBarItem setBadgeValue:@"100"];

承上面兩項，實際顯示的圖形會被系統再處理一次
