// Fetch yourText for this row from your data source.. Nsstring *yourText = [yourArray objectAtIndex:indexPath.row]; CGSize lableWIDth = CGSizeMake(300,CGfloat_MAX); // 300 is fixed wIDth of label. You can change this value CGSize requiredSize = [yourText sizeWithFont:[UIFont FontWithname:@"Times New Roman" size:19] constrainedToSize:lableWIDth lineBreakMode:NSlineBreakByWorDWrapPing]; // You can put your desire Font // Here,you will have to use this requiredSize and based on that,adjust height of your cell. I have added 10 on total required height of label and it will have 5 pixels of padding on top and bottom. You can change this too. int calculatedHeight = requiredSize.height+10; return (float)calculatedHeight;
正是这句话(如何将其转换为swift):
CGSize requiredSize = [yourText sizeWithFont:[UIFont FontWithname:@"Times New Roman" size:19] constrainedToSize:lableWIDth lineBreakMode:NSlineBreakByWorDWrapPing]
我尝试将其转换为(但它不能作为原始目标-c):
var requiredSize: CGSize = originalString.sizeWithAttributes([NSFontAttributename: UIFont.systemFontOfSize(19.0)])解决方法 也许有可能在没有UILabel的情况下做到这一点,但这很好用.
let label = UILabel(frame: CGRect(x: 0,y: 0,wIDth: 300,height: 10000))label.text = someTextlabel.numberOflines = 100label.Font = UIFont(name: "Times New Roman",size: 19.0)label.sizetoFit()return label.frame.height + 10总结
