我要去另一頁，另一頁有UITabbarcontroller。圖標圖像不顯示在iOS 7的tabbar上？
有：
- 首頁2 CutPipe 3件4法蘭5.設置
現在這五個名字都出現了，但我有沒有顯示這五個圖標和圖像屏幕顯示黑色和如果我做clearcolor然後屏幕顯示灰色。
我也想要如何控制高度UITabbarcontroller。
我的問題是圖標圖像不顯示在tabbar上。
我還在UITabbar上添加背景圖像，並在圖標圖像上添加。但它沒有顯示。
這是我的代碼。在您的標籤實現以下
rvc_Home.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Home" image:[[UIImage imageNamed:@"home.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] selectedImage:[UIImage imageNamed:HOME_SELECTED_IMAGE]];
編輯
添加代碼：
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
// Retrieve the last view name
NSInteger firstValue = [[NSUserDefaults standardUserDefaults] integerForKey:@"firstValue"];
if (firstValue == 10) {
[self method_Tabs];
}
}
-(void)method_Tabs{
// Set the name of the view
[[NSUserDefaults standardUserDefaults] setInteger:11 forKey:@"firstValue"];
my_Tabbar = [[UITabBarController alloc] init]; // how to control height of my_Tabbar?
// my_Tabbar.view.frame=CGRectMake(0, 100, 320,30); // is there any way to control this
// my_Tabbar.view.backgroundColor = [UIColor redColor];
my_Tabbar.tabBar.barTintColor = [UIColor clearColor];
self.tabBarController.tabBar.translucent = false;
// this will give selected icons and text your apps tint color
my_Tabbar.tabBar.tintColor = [UIColor blueColor];
[[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Bold" size:13.0f],
NSForegroundColorAttributeName : [UIColor colorWithRed:.5 green:.5 blue:.5 alpha:1]

圖像將不會顯示如果太大了。你有沒有嘗試減小圖像的幀大小？如果它適用於小圖標圖像，請嘗試[icon finder]（https://www.iconfinder.com/）。 – GoGreen
圖標大小僅爲每張圖片120 * 98 – Tina
請嘗試圖片尺寸小於或等於48 x 32. – GoGreen
