iphone - 尝试自定义 ABPersonViewController - 无法循环遍历其 subview

Question

我试图利用 ABPersonViewController 的简单性，同时稍微自定义它的外观以匹配我的应用程序的外观和感觉。

我对 ABPersonViewController 进行了子类化，并使用 this technique ，我循环遍历 ABPersonViewController 的 View 层次结构，这是我的输出:

UIView: 0x5a45d80; frame = (0 0; 320 416); autoresize = W+H; layer = >   | ABPersonTableView: 0x6041a00; baseClass = UITableView; frame = (0 0; 320 416); clipsToBounds = YES; autoresize = W+H; layer = ; contentOffset: {0, 0}>   |    | ABMultiCell: 0x5a50080; baseClass = UITableViewCell; frame = (0 94; 320 45); autoresize = W; tag = 10; layer = >   |    |    | UIGroupTableViewCellBackground: 0x5a678d0; frame = (9 0; 302 45); autoresize = W; layer = >   |    |    | UITableViewCellContentView: 0x5a62670; frame = (10 1; 300 43); layer = >   |    |    |    | ABMultiCellContentView_Simple: 0x5a4fef0; frame = (0 0; 300 43); text = '(555) 555-5555'; clipsToBounds = YES; layer = >   |    |    |    |    | UILabel: 0x5a61590; frame = (5 14.54; 70 16); text = 'mobile'; clipsToBounds = YES; userInteractionEnabled = NO; layer = >   |    |    |    |    | ABDividerView: 0x5a62ff0; frame = (79 0; 1 44); alpha = 0; layer = >   |    |    |    |    |    | ABSteadfastLineView: 0x5a53ab0; frame = (0 0; 1 44); layer = >   |    |    |    |    | ABHighlightingTextField: 0x5a53c30; baseClass = UITextField; frame = (85 12; 210 21); text = '(555) 555-5555'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    |    |    | UITextFieldLabel: 0x5a53db0; frame = (0 0; 210 19); text = '(530) 305-0835'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = >   |    | UIView: 0x5a5b300; frame = (0 0; 320 94); layer = >   |    |    | ABPersonTableHeaderView: 0x5a444b0; frame = (0 0; 320 94); clipsToBounds = YES; autoresize = W; layer = >   |    |    |    | ABPersonImageView: 0x5a449c0; baseClass = UIControl; frame = (19 15; 64 64); clipsToBounds = YES; autoresize = RM+BM; layer = >   |    |    |    |    | ABClippingImageView: 0x5a6aae0; frame = (0 0; 64 64); opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    |    | ABImageWellLabelView: 0x5a6c0b0; frame = (0 0; 64 64); alpha = 0; opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    | ABPersonNameEditingViewContainer: 0x5a4a9e0; frame = (101 15; 530 64); alpha = 0; autoresize = W+BM; layer = >   |    |    |    |    | ABMultiCellContentView_Name: 0x5a4b480; frame = (1 0; 208 64); clipsToBounds = YES; layer = >   |    |    |    |    |    | ABHighlightingTextField: 0x5a4d7c0; baseClass = UITextField; frame = (-5 12; 10 21); text = 'First Name'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; tag = 1; layer = >   |    |    |    |    |    |    | UITextFieldLabel: 0x5a4b3e0; frame = (-10 0; 10 19); text = 'First Name'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    |    |    | ABHighlightingTextField: 0x5a50a90; baseClass = UITextField; frame = (-5 56; 10 21); text = 'Last Name'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; tag = 2; layer = >   |    |    |    |    |    |    | UITextFieldLabel: 0x5a4e5d0; frame = (-10 0; 10 19); text = 'Last Name'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    |    |    | ABDividerView: 0x5a52300; frame = (0 44; 0 1); layer = >   |    |    |    |    |    |    | ABSteadfastLineView: 0x5a525d0; frame = (0 0; 0 1); layer = >   |    |    |    |    |    | ABHighlightingTextField: 0x5a52400; baseClass = UITextField; frame = (-5 100; 10 21); clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; tag = 3; layer = >   |    |    |    |    |    |    | UITextFieldLabel: 0x5a5a4e0; frame = (-8 0; 10 19); text = 'Company'; clipsToBounds = YES; opaque = NO; userInteractionEnabled = NO; layer = >   |    |    |    |    |    | ABDividerView: 0x5a53f00; frame = (0 88; 0 1); layer = >   |    |    |    |    |    |    | ABSteadfastLineView: 0x5a53f80; frame = (0 0; 0 1); layer = >   |    |    |    | ABPersonNameDisplayView: 0x5a45cf0; baseClass = UIControl; frame = (97 15; 204 64); autoresize = W; layer = >   |    |    |    |    | UILabel: 0x5a4bbd0; frame = (0 21; 109 23); text = 'First Name Last Name'; clipsToBounds = YES; autoresize = W; userInteractionEnabled = NO; layer = >   |    |    |    |    | UILabel: 0x5a4c020; frame = (0 0; 204 0); clipsToBounds = YES; autoresize = W; userInteractionEnabled = NO; layer = >   |    | UIImageView: 0xcc032a0; frame = (0 409; 320 7); alpha = 0; opaque = NO; autoresize = TM; userInteractionEnabled = NO; layer = >   |    | UIImageView: 0xcc03350; frame = (313 262; 7 154); alpha = 0; opaque = NO; autoresize = LM; userInteractionEnabled = NO; layer = >

甜甜的!所以我应该能够递归地循环遍历根 UIView 的 subview ，并改变我的内心内容。

问题是，执行此循环时，根 UIView 只显示一个 subview (ABPersonTableView)，我不能再深入了。

有什么想法吗？ ABPersonTableView 是一个隐藏其创建/包含的所有内容的私有(private)类吗？

我可以通过在递归循环中执行此操作来更改表格的背景颜色:

if ([subview isKindOfClass:[UITableView class]]) {    ((UITableView *)subview).backgroundColor = [UIColor purpleColor];}

但是，我无法访问任何 UILabels，因为我无法访问 ABPersonTableView 的任何 subview 。

有什么想法吗？

Answer 1

你被困住了，因为苹果只提供两种方法:

1. Apple 的内置、自动、 super 简单的外观和感觉方式(不可自定义)
2. 您可以通过对 AddressBook 的低级调用自行完成所有操作

ABPersonViewController 及其 subview 不应该被修改，并且这样做不能保证与 future 的软件更新一起使用。

原因是苹果想要一致的外观和感觉。

如果您确实需要匹配应用程序的外观和感觉，则必须采用上面的方法 2) 并从头开始重新实现整个过程。这不一定很难，但肯定很耗时。
