Objectivec 如何拦截点击 UITextView 中的链接

Update: From ios10,

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

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.这是最好的方法.

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

你需要在你的代表中实现openURL:.

现在，要让应用程序从新的子类UIApplication开始，请找到文件main.我参与了你的项目.在这个 bootstrap 应用程序的小文件中，通常有这样一行:

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

第三个参数是应用程序的类名.因此，将这一行替换为:

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

这对我起了作用.
