使用uilabel重新自调整高度后显示横线和竖线问题
这个使用uilabel自调节高度发现的问题，代码如下：
//content label
NSString *contentValue = ((MessageDetailRecord *)[self.entriesArray objectAtIndex:indexPath.row]).content;
CGFloat width = 0.0f;
CGSize orignalSize;
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
if ([GeneralInfo getDeviceSystemVer]){
orignalSize = [contentValue sizeWithAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:20.0f]}];
width = orignalSize.width;
}else{
width = [contentValue sizeWithFont:[UIFont systemFontOfSize:20.0f ]].width;
}
#pragma clang diagnostic pop
//set the most large width
if (width > cell.frame.size.width - 90.0f) {
width = cell.frame.size.width - 90.0f;
}
UILabel *content = [[UILabel alloc]initWithFrame:CGRectMake(0.0f, 0.0f, width, 0.0f)];
self.messageContentLabel = content;
self.messageContentLabel.font = [UIFont systemFontOfSize:20.0];
self.messageContentLabel.backgroundColor = [UIColor clearColor];
self.messageContentLabel.numberOfLines = 0;
self.messageContentLabel.adjustsFontSizeToFitWidth = YES;
self.messageContentLabel.lineBreakMode = NSLineBreakByWordWrapping;
self.messageContentLabel.backgroundColor = [UIColor colorWithRed:241/255.0f green:241/255.0f blue:241/255.0f alpha:1.0];
CGRect labelFrameContent = self.messageContentLabel.frame;
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
if ([GeneralInfo getDeviceSystemVer]) {
NSDictionary *stringAttributes = [NSDictionary dictionaryWithObject:self.messageContentLabel.font forKey: NSFontAttributeName];
labelFrameContent.size = [contentValue boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)
options:NSStringDrawingTruncatesLastVisibleLine|NSStringDrawingUsesLineFragmentOrigin
attributes:stringAttributes context:nil].size;
}else{
labelFrameContent.size = [contentValue sizeWithFont:self.messageContentLabel.font
constrainedToSize:CGSizeMake(width, CGFLOAT_MAX)
lineBreakMode:self.messageContentLabel.lineBreakMode];
}
#pragma clang diagnostic pop
//adjust the height
if (labelFrameContent.size.height < 50.0f) {
labelFrameContent.size.height = 50.0f;
}
labelFrameContent.size.width += 10.0f;
if (labelFrameContent.size.width > cell.frame.size.width - 90.0f) {
labelFrameContent.size.width = cell.frame.size.width - 90.0f;
}
labelFrameContent.origin.x = 70.0f;
labelFrameContent.origin.y = self.cellDateLabel.frame.size.height + 10.0f;
self.messageContentLabel.frame = labelFrameContent;
[cell.contentView addSubview:self.messageContentLabel];
解决方法是使用uitextview来替换即可
UITextView *content = [[UITextView alloc]initWithFrame:CGRectMake(0.0f, 0.0f, width, 0.0f)];
self.messageContentLabel = content;
[content release];
self.messageContentLabel.font = [UIFont systemFontOfSize:16.0f];
self.messageContentLabel.backgroundColor = [UIColor clearColor];
self.messageContentLabel.scrollEnabled = NO;
self.messageContentLabel.userInteractionEnabled = NO;
//self.messageContentLabel.numberOfLines = 0;
//self.messageContentLabel.adjustsFontSizeToFitWidth = YES;
// self.messageContentLabel.lineBreakMode = NSLineBreakByWordWrapping;
self.messageContentLabel.backgroundColor = [UIColor colorWithRed:241/255.0f green:241/255.0f blue:241/255.0f alpha:1.0];
self.messageContentLabel.text = contentValue;
self.messageContentLabel.textColor = [UIColor grayColor];
CGRect labelFrameContent = self.messageContentLabel.frame;
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
if ([GeneralInfo getDeviceSystemVer])
{
labelFrameContent.size = [contentValue boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)
options:(NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading)
attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:17.0f]}
context:nil].size;
}
else
{
labelFrameContent.size = [contentValue sizeWithFont:self.messageContentLabel.font constrainedToSize:CGSizeMake(width, CGFLOAT_MAX)];
}
#pragma clang diagnostic pop
注意：这个在ios 7.0以前的版本如果使用uitextview的话布局会有问题，如果使用uilabel的话在ios7.0上又会出现横竖线。所以最终的解决方案是区分当前的版本对待。
