ios - AsyncDisplayKit ASButtonNode setTitle 不起作用

Question

我用AsyncDisplayKit写button，用ASButtonNode，但是用时不能设置标题- (void)setAttributedTitle:(NSAttributedString *)状态的标题:(ASButtonState)state 。它可以响应 Action ，但没有标题。我担心还是需要设置其他东西？

代码如下:

NSDictionary *placeholderAttrs = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue-LightItalic" size:14.0f] , NSForegroundColorAttributeName: [UIColor greenColor] };

ASButtonNode *button = [[ASButtonNode alloc] init];
[button setAttributedTitle:[[NSAttributedString alloc] initWithString:@"button" attributes:placeholderAttrs] forState:ASButtonStateNormal];
[button addTarget:self action:@selector(action:) forControlEvents:ASControlNodeEventTouchUpInside];
[button setFrame:CGRectMake(20, 20, 100, 44)];
button.backgroundColor = [UIColor redColor];
button.titleNode.displaysAsynchronously = NO;
[self.view addSubnode:button];

谢谢。

@leo，看起来您可能只需要在将 ASButtonNode 添加到 View 之前对其进行测量。

[按钮尺寸:...];
