+# DisableSplitPin
+
+- **功能描述：** 禁用Struct的split功能
+- **使用位置：** USTRUCT
+- **引擎模块：** Pin
+- **元数据类型：** bool
+- **常用程度：** ★★
+
+对于某些Struct，特别是只有一个成员变量的结构，有时候如果按照默认的展开则会显得很怪。这个时候就希望能够禁用掉这个功能。但是注意依然可以手动在蓝图里Break来访问成员变量。如果在蓝图里也不想暴露成员变量访问，那应该在UPROPERTY上不能加BlueprintReadWrite/BlueprintReadOnly
+
+在源码里搜索，如FGameplayTag，FPostProcessSettings，FSlatePostSettings
+
+## 测试代码：
+
+```cpp
+USTRUCT(BlueprintType, meta = (DisableSplitPin))
+struct INSIDER_API FMyStruct_DisableSplitPin
+{
+	GENERATED_BODY()
+
+	UPROPERTY(BlueprintReadWrite, EditAnywhere)
+	float MyFloat;
+	UPROPERTY(BlueprintReadWrite, EditAnywhere)
+	FString MyString;
+};
+
+USTRUCT(BlueprintType)
+struct INSIDER_API FMyStruct_WithSplitPin
+{
+	GENERATED_BODY()
+
+	UPROPERTY(BlueprintReadWrite, EditAnywhere)
+	float MyFloat;
+	UPROPERTY(BlueprintReadWrite, EditAnywhere)
+	FString MyString;
+};
+```
