10.3 系统，Label高度自适应不行了

leizGit commented 7 years ago

设置preferredMaxLayoutWidth 可以解决，但是如果是使用自动布局，一般我们不知道Label的宽度

SiTianyu commented 7 years ago

确实，求作者解决

啊，希望作者能看到啊，10.3的确是无法高度自适应了

已经有解决方法，在cell里进行布局之前先对contentView进行约束就可以了，我的是这样解决的 [self.contentView mas_makeConstraints:^(MASConstraintMaker *make) { make.edges.equalTo(self); }];

有约束冲突,需要设置preferredMaxLayoutWidth 会报UITableViewCellContentView .width = 375 与 UITableViewCellContentView .width = 0 冲突. 如果返回的高度写死就没有冲突了

如果xib布局中设置cell的高度为350，如果[self.contentView mas_makeConstraints:^(MASConstraintMaker *make) { make.edges.equalTo(self); }];这样解决的话，在iPhone6中会报UITableViewCellContentView .width = 375 与 UITableViewCellContentView .width = 350 冲突.

@lovemo 设置contentView的约束，label显示没问题，但是其他约束出现了问题

直接在 awakeFromNib 那里把 preferredMaxLayoutWidth 写进去不可以吗？

    [cell.contentView mas_makeConstraints:^(MASConstraintMaker *make) {

} else {
```
// If not using auto layout, you have to override "-sizeThatFits:" to provide a fitting size by yourself.
// This is the same method used in iOS8 self-sizing cell's implementation.
// Note: fitting height should not include separator view.

BOOL inherited = ![cell isMemberOfClass:UITableViewCell.class];
BOOL overrided = [cell.class instanceMethodForSelector:selector] != [UITableViewCell instanceMethodForSelector:selector];

    NSAssert(NO, @"Customized cell must override '-sizeThatFits:' method if not using auto layout.");
}
fittingSize = [cell sizeThatFits:CGSizeMake(contentViewWidth, 0)];
```
}

// Add 1px extra space for separator line if needed, simulating default UITableViewCell. if (self.separatorStyle != UITableViewCellSeparatorStyleNone) { fittingSize.height += 1.0 / [UIScreen mainScreen].scale; }

if (autoLayoutEnabled) { [self fd_debugLog:[NSString stringWithFormat:@"calculate using auto layout - %@", @(fittingSize.height)]]; } else { [self fd_debugLog:[NSString stringWithFormat:@"calculate using frame layout - %@", @(fittingSize.height)]]; }

return fittingSize.height; } 我这样修复了

if (IOS_VERSION > 10.2) {

  [cell.contentView mas_makeConstraints:^(MASConstraintMaker *make) {
      make.left.mas_equalTo(0).priorityLow();
      make.right.mas_equalTo(0).priorityLow();
  }];

} 重点在这里

zigang commented 7 years ago

@ChenYanTao666 preferredMaxLayoutWidth这个你是怎么设置呢？设置成0？

yansun2006 commented 7 years ago

这么好的库，希望作者能持续更新

leizGit commented 7 years ago

@ChenYanTao666 添加了 if (SystemVersion > 10.2){ [templateLayoutCell.contentView mas_makeConstraints:^(MASConstraintMaker *make) { make.left.mas_equalTo(0).priorityLow(); make.right.mas_equalTo(0).priorityLow(); }]; } 之后，还是不对，看看下图，上面的间距是有问题，间距被拉大了，下面的是正常的
