原标题:Highlight a text in UIWebView

i 正在开发一个SOS应用程序,有多个信箱:IDWebView。 i 愿意选择并突出网上意见中的案文,但希望储存这一选择,以便在用户重新估价时重新选择相同的案文。 如何做到这一点?

Store it in user defaults and read them back on relaunch.
If the textfield has a tag property you could write/read the tag of the selection from user defaults

例:

// access the user defaults for your app:
defaults = [NSUserDefaults standardUserDefaults];

// write to user defaults
[defaults setInteger:myTextField.tag forKey:@"selectedFieldsTag"];

// read from user defaults (on launch?)
NSInteger selectedTag = [defaults integerForKey:@"selectedFieldsTag"];

EDIT:以上为存储信息和检索工作将进行罚款,但如果你开始储存更多的数据,而不仅仅是一个标签,那么你可能想考虑使用核心数据或另一种储存/检索手段。 就用户选择什么而言,这远不如说是微不足道。 这一联系解释了如何做到:
