ios - UINavigationBar 设置图像未完全绘制

Question

我正在尝试将图像设置为导航栏的 ViewController，将其设置为未完全绘制到 NavigationBar 后。无法理解为什么会这样。

图片大小为90高宽750

任何人都可以让我知道我需要做什么吗？

[self.navigationController setToolbarHidden:YES animated:NO];
self.title = NSLocalizedString(@"Dashboar", @"Dashboard");
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName : [UIColor whiteColor]};
UIImage *currentImage =  [[UIImage imageNamed:@"bg.png"]
                          resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0) resizingMode:UIImageResizingModeStretch];
[self.navigationController.navigationBar setBackgroundImage:currentImage forBarMetrics:UIBarMetricsDefault]; 

Answer 1

[self.navigationController setToolbarHidden:YES animated:NO];
self.title = NSLocalizedString(@"Dashboar", @"Dashboard");
self.navigationController.navigationBar.barTintColor = [UIColor whiteColor];
self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName : [UIColor whiteColor]};

您必须为多个设备设置此背景图像的确切宽度。

if (IS_IPHONE4) {
[navController.navigationBar setBackgroundImage:[UIImage imageNamed:@"TopBar_iphone4.png"] forBarMetrics:UIBarMetricsDefault];
}
if (IS_IPHONE5) {
[navController.navigationBar setBackgroundImage:[UIImage imageNamed:@"TopBar_iphone5.png"] forBarMetrics:UIBarMetricsDefault];
}
if (IS_IPHONE6) {
[navController.navigationBar setBackgroundImage:[UIImage imageNamed:@"TopBar_iphone6.png"] forBarMetrics:UIBarMetricsDefault];
}
if (IS_IPHONE6Plus) {
[navController.navigationBar setBackgroundImage:[UIImage imageNamed:@"TopBar_iphone6plus.png"] forBarMetrics:UIBarMetricsDefault];
 }
   [[UINavigationBar appearance] setBackgroundImage:NavigationPortraitBackground forBarMetrics:UIBarMetricsDefault];

我必须检查这段代码是否适合我。
