Question

我正在尝试将iPad的自定义快捷方式添加到我的应用中。但是，使用下面的代码我无法看到它们正常工作。当我按下命令键时，我得到发现模式，但是当我按下命令+ f时没有任何反应。我做错了什么？

#pragma mark - UIResponder

- (BOOL)canBecomeFirstResponder {
    return YES;
}

- (NSArray *)keyCommands {
    return @[
         [UIKeyCommand keyCommandWithInput:@"f" modifierFlags:0 action:@selector(backspacePressed:) discoverabilityTitle:@"New message"]
    ];
}

- (void)backspacePressed:(UIKeyCommand *)command {
    NSLog(@"Backspace key was pressed");
}

原来，为了让我能够注册cmd + f，我需要将/** * Return the number of characters that the two strings overlap * @param str1 * @param str2 * @param min - minimum required overlap * @return The number they actually overlap for first detected overlap */ static int numOverlap(String str1, String str2, int min) { int pos = getOverlap(str1, str2, min); if (pos < 0) { return -1; } char a[] = str1.toCharArray(); char b[] = str2.toCharArray(); int i = 0; while (a[i + st1Pos] == b[i + st2Pos]) { i++; if ((i + st1Pos >= a.length) || (i + st2Pos >= b.length)) { break; } } return i; }从$.ajax({ url: path, method: 'GET', async: true, success:function(data) { $(this.$modal).append(data); //-- call the form js theFormData(); }) }); function theFormData(){ //-- add your code here, this should now be able to bind to your form as it //-- has something to hook onto }更改为ko.applyBindings({});。
