星期一, 六月 6th, 2011方法1：
1 2 3 | NSString *str = [NSString stringWithString:@"People \nforget that @BillGates had a sexy 1/4-inch thick slate back in 1993 from NEC. Whatever happens this week will NOT be about hardware!"]; CGSize size = [str sizeWithFont:[UIFont systemFontOfSize:17.0f] constrainedToSize:CGSizeMake(310.0f, FLT_MAX) lineBreakMode:UILineBreakModeWordWrap]; |
方法2：
1 2 3 4 5 6 7 8 9 | UILabel *label = [[UILabel alloc] init]; label.numberOfLines = 0; label.font = [UIFont systemFontOfSize: 17.0f]; label.lineBreakMode = UILineBreakModeWordWrap; label.text = str; CGRect labelFrame = label.frame; labelFrame.size.width = 310; label.frame = labelFrame; [label sizeToFit]; |
