我希望我的UILabel在这里显示为水平和中心。垂直在叠加层中我想要重叠UIView(在行家lorem ipsum文本后面的浅色alpha区域)调整大小以在顶部和底部给我10个像素的填充,但仍然自动拉伸其宽度。有谁能指出我正确的方向?我想让它尽可能地充满活力。
以下是我要看到的内容:
descView = [[UIView alloc] initWithFrame:CGRectMake(0, 64, self.view.bounds.size.width, 160)];
descView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
descView.backgroundColor = [UIColor colorWithWhite:0 alpha:0.5];
descLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 600, 120)];
descLabel.center = CGPointMake(self.view.bounds.size.width/2, descView.bounds.size.height/2);
descLabel.backgroundColor = [UIColor clearColor];
descLabel.opaque = NO;
descLabel.textAlignment = UITextAlignmentCenter;
descLabel.text = currentPhoto.desc;
descLabel.numberOfLines = 5;
descLabel.textColor = [UIColor whiteColor];
descLabel.autoresizingMask = UIViewAutoresizingFlexibleMargins;
CGRect frame = descLabel.frame;
frame.origin.x = (descView.frame.size.width - descLabel.frame.size.width)/2;
descLabel.frame = frame;
[self.view addSubview:descView];
[descView addSubview:descLabel];

使用https://gist.github.com/2596057(Thats Marco Arment的子类UILabel)
(或)您可以使用resizeHeightToFitText方法的代码执行相同的操作而不使用hte IPInsetLabel
一旦标签的大小适合文字,请根据高度和宽度设置标签的原点
