请不要只重复苹果课程中的文字参考
- 当然我已经读过了。

谢谢。

推荐答案

更新：来自 ios10 ，

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction;

来自 ios7 及更高版本 UITextView 具有委托方法：

From ios7 and Later UITextView has the delegate method:

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange *NS_DEPRECATED_IOS(7_0, 10_0, "Use textView:shouldInteractWithURL:inRange:forInteractionType: instead");*

拦截链接的点击次数。这是最好的方法。

to intercept the clicks to links. And this is the best way to do it.

对于 ios6 和更早的一个很好的方法是通过继承 UIApplication 并覆盖 - （BOOL）openURL：（NSURL *）url

For ios6 and earlier a nice way to do this is to by subclassing UIApplication and overwriting the -(BOOL)openURL:(NSURL *)url

@interface MyApplication : UIApplication {

}

@end

@implementation MyApplication


-(BOOL)openURL:(NSURL *)url{
    if  ([self.delegate openURL:url])
         return YES;
    else
         return [super openURL:url];
}
@end

您需要实施 openURL：。

现在，要让应用程序以 UIApplication 的新子类开头，找到你的文件main.m项目。在这个引导你的应用程序的小文件中，通常有这一行：

Now, to have the application start with your new subclass of UIApplication, locate the file main.m in your project. In this small file that bootstraps your app, there is usually this line:

int retVal = UIApplicationMain(argc, argv, nil, nil);

第三个参数是应用程序的类名。因此，将此行替换为：

The third parameter is the class name for your application. So, replacing this line for:

int retVal = UIApplicationMain(argc, argv, @"MyApplication", nil);

这对我有用。
