使用阈值禁用AutoCorrect

Question

我在我的潜意识测试中遇到了一些问题，由于设备默认设置，文本会被自动更正。

有没有办法让我用Subliminal禁用整个设备上的自动更正？我能以某种方式导航到设备设置吗？

潜意识无法导航到设备设置，但您的测试可以使用一点method swizzling覆盖默认的文本字段自动更正类型

// In the test that exercises the text fields,
// or a base test class of multiple tests that exercise text fields
#import <objc/runtime.h>

- (void)setUpTest {
    // `dispatch_once` in case this is a base test class,
    // where this method would be called multiple times
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        struct objc_method_description autocorrectionTypeMethodDescription = protocol_getMethodDescription(@protocol(UITextInputTraits), @selector(autocorrectionType), NO, YES);
        // (Re)implement `-[UITextField autocorrectionType]` to return `UITextAutocorrectionTypeNO`.
        IMP noAutocorrectionTypeIMP = imp_implementationWithBlock(^(UITextField *_self){ return UITextAutocorrectionTypeNo; });
        class_replaceMethod([UITextField class], @selector(autocorrectionType), noAutocorrectionTypeIMP, autocorrectionTypeMethodDescription.types);
    });
}
