Question

在我的应用程序中，我有一个用于OTP输入的自定义编辑文本，我想为此视图创建一个转换方法，以便用户可以看到实际输入一秒钟，它将替换为子弹。就像使用密码输入的原生edittext一样。

private class PinTransformationMethod extends PasswordTransformationMethod {

        private char BULLET = '\u2B24';

        @Override
        public CharSequence getTransformation(CharSequence source, View view) {
            return new PasswordCharSequence(source);
        }

        private class PasswordCharSequence implements CharSequence {
            private final CharSequence source;

            public PasswordCharSequence(@NonNull CharSequence source) {
                this.source = source;
            }

            @Override
            public int length() {
                return source.length();
            }

            @Override
            public char charAt(int index) {
                return BULLET;
            }

            @Override
            public CharSequence subSequence(int start, int end) {
                return new PasswordCharSequence(this.source.subSequence(start, end));
            }
        }

    }

这是我从PasswordTransformation方法扩展的转换方法。它可以完美地替换我对Bullets的输入，但是我无法显示输入几秒钟，我该如何实现呢？

如果有人需要做这样的事情，我在我的char - (void)disableWaitForIdle { SEL originalSelector = NSSelectorFromString(@"waitForQuiescenceIncludingAnimationsIdle:"); SEL swizzledSelector = @selector(doNothing); Method originalMethod = class_getInstanceMethod(objc_getClass("XCUIApplicationProcess"), originalSelector); Method swizzledMethod = class_getInstanceMethod([self class], swizzledSelector); method_exchangeImplementations(originalMethod, swizzledMethod); } - (void)doNothing { // no-op }中使用了Thread.sleep，因为 500 毫秒延迟method
