我正尝试通过自动布局来实现自定义表格单元,如下所示,但是由于某种原因,我没有得到预期的结果。
预期:
实际:
我的观察是:
bar
元素应该是垂直的蓝色条,但显示不正确; 请分享一些我做错了的事情。预先感谢
UITableViewCell代码在下面:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.infoContainer = [[UIView alloc] init];
self.title = [[UILabel alloc] init];
self.time = [[UILabel alloc] init];
self.bar = [[UIView alloc] init];
[self.infoContainer addSubview:self.bar];
[self.infoContainer addSubview:self.title];
[self.infoContainer addSubview:self.time];
[self.contentView addSubview:self.infoContainer];
self.infoContainer.translatesAutoresizingMaskIntoConstraints = NO;
self.title.translatesAutoresizingMaskIntoConstraints = NO;
self.time.translatesAutoresizingMaskIntoConstraints = NO;
self.bar.translatesAutoresizingMaskIntoConstraints = NO;
[self.infoContainer.leftAnchor constraintEqualToAnchor:self.contentView.leftAnchor constant:18].active = YES;
[self.infoContainer.rightAnchor constraintEqualToAnchor:self.contentView.rightAnchor constant:-18].active = YES;
[self.infoContainer.topAnchor constraintEqualToAnchor:self.contentView.topAnchor constant:10].active = YES;
self.infoContainer.backgroundColor = [UIColor yellowColor];
[self.bar.leftAnchor constraintEqualToAnchor:self.infoContainer.leftAnchor constant:0].active = YES;
[self.bar.topAnchor constraintEqualToAnchor:self.infoContainer.topAnchor constant:0].active = YES;
[self.bar.bottomAnchor constraintEqualToAnchor:self.infoContainer.bottomAnchor constant:0].active = YES;
[self.bar.heightAnchor constraintEqualToAnchor:self.infoContainer.heightAnchor].active = YES;
[self.bar.widthAnchor constraintEqualToConstant:10];
self.bar.backgroundColor = [UIColor blueColor];
[self.title.leftAnchor constraintEqualToAnchor:self.bar.rightAnchor constant:15].active = YES;
[self.title.rightAnchor constraintEqualToAnchor:self.infoContainer.rightAnchor constant:0].active = YES;
[self.title.topAnchor constraintEqualToAnchor:self.infoContainer.topAnchor constant:0].active = YES;
[self.time.leftAnchor constraintEqualToAnchor:self.title.leftAnchor constant:0].active = YES;
[self.time.rightAnchor constraintEqualToAnchor:self.title.rightAnchor constant:0].active = YES;
[self.time.topAnchor constraintEqualToAnchor:self.title.bottomAnchor constant:10].active = YES;
}
return self;
}
在表格视图中,我有:
self.recentView.rowHeight = UITableViewAutomaticDimension;
self.recentView.estimatedRowHeight = 64.0f;
谢谢!
答案 0 :(得分:-1)
自动高度完全取决于上下挂钩的约束,因此您会错过2个约束
1-
[self.infoContainer.bottomAnchor constraintEqualToAnchor:self.contentView.bottomAnchor constant:10].active = YES;
2-
[self.time.bottomAnchor constraintEqualToAnchor:self.infoContainer.bottomAnchor constant:10].active = YES;
提示::如果您在此处设置顶部和底部约束
[self.bar.topAnchor constraintEqualToAnchor:self.infoContainer.topAnchor constant:0].active = YES;
[self.bar.bottomAnchor constraintEqualToAnchor:self.infoContainer.bottomAnchor constant:0].active = YES;
然后不需要
[self.bar.heightAnchor constraintEqualToAnchor:self.infoContainer.heightAnchor].active = YES;
