在我努力升级我的应用程序以支持IOS7时,我发现UIPageControl它不支持UIImageView.他们改变了它.
我是子类化UIPageControl,以便将自定义圈子改为常规圈子(附上示例)
我的班级是:
- (id)initWithFrame:(CGRect)frame
{
// if the super init was successfull the overide begins.
if ((self = [super initWithFrame:frame]))
{
// allocate two bakground images, one as the active page and the other as the inactive
activeImage = [UIImage imageNamed:@"active_page_image.png"];
inactiveImage = [UIImage imageNamed:@"inactive_page_image.png"];
}
return self;
}
// Update the background images to be placed at the right position
-(void) updateDots

我有一个UINavigationController,其中包含一个ViewController,它在视图中有两个按钮.在7之前的IOS中,导航栏将视图向下推到导航栏下方,这样我就能看到它.在IOS 7中,UINavigationController不执行此操作,按钮位于导航栏后面.
这是IOS 7:

这是旧的IOS 6视图:

我查看了ViewController.view.frame.origin.y并看到它的开头是0px(在IOS 7上)我确信它在那里,但在视图后面,因为我已经改变了按钮的原点并看到了它们.
我是网络开发的新手,无法找到明确的答案.
可以在Swapor 3的Vapor中使用Bootstrap吗?
问题只发生在Xcode 8和IOS 10中.如果我使用XCode 8和IOS 9,它的工作正常.
func resetKeychain() {
if !self.keychainItemData.isEmpty {
let tempDict = self.dictToSecItemData(self.keychainItemData)
var junk = noErr
junk = SecItemDelete(tempDict as CFDictionary)
assert(junk == noErr || junk == errSecItemNotFound, "Failed to delete current dict")
}
self.keychainItemData[kSecAttrAccount] = ""
self.keychainItemData[kSecAttrLabel] = ""
self.keychainItemData[kSecAttrDescription] = ""
self.keychainItemData[kSecValueData] = ""
}

断言总是在IOS 10中发生并且应用程序崩溃
有任何想法吗?
