我一直在尝试使用
swift做一个带有标签的动态单元格来支持heightForRowAtIndexPath中的
IOS7,但我只找到了objective-c代码,是否有可能帮助我将这段代码重写为swift？
// 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 = someText label.numberOfLines = 100 label.font = UIFont(name: "Times New Roman",size: 19.0) label.sizeToFit() return label.frame.height + 10
