我有一个简单的表单来保存用户，但无法显示错误消息
我具有与保存“客户”完全相同的结构，并且可以使用，但是当我尝试将其复制到用户时，则无法使用
我的日志错误：

我简直不明白为什么它不显示错误消息，我很确定所记录的内容本身不是错误...任何帮助将不胜感激！
答案 0 :(得分：3)
可能不是失败的原因，但是bindingresult必须遵循正在验证的参数。您可以在答案here
上看到更多详细信息所以改变：
- (void)submitWithOptions:(NSString *)options {
NSLog(@"Submit button tapped");
}
- (void) close {
NSLog(@"Close button tapped");
}
