UI初级 Label
UILabel的部分常用属性
1 //TODO:UILabel 2 CGFloat nameLabelX = 50; 3 CGFloat nameLabelY = 200; 4 CGFloat nameLabelW = 80; 5 CGFloat nameLabelH = 40; 6 7 UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(nameLabelX, nameLabelY, nameLabelW, nameLabelH)]; 8 nameLabel.backgroundColor = [UIColor cyanColor]; 9 10 //设置文本显示的字 11 nameLabel.text = @"用户名"; 12 13 //设置文本居中 14 nameLabel.textAlignment = NSTextAlignmentCenter; //居中 15 16 //将nameLabel添加到window 视图上 17 [self.window addSubview:nameLabel]; 18 19 //创建pswLabel对象,并设置frame 20 UILabel *pswLabel = [[UILabel alloc] initWithFrame:CGRectMake(nameLabelX, nameLabelY + 50, nameLabelW, nameLabelH)]; 21 22 pswLabel.backgroundColor = [UIColor cyanColor]; 23 24 pswLabel.text = @"密码"; 25 26 pswLabel.textAlignment = NSTextAlignmentCenter; 27 28 [self.window addSubview:pswLabel]; 29 30 //用户名后面的label 31 UILabel *nameBackLabel = [[UILabel alloc] initWithFrame:CGRectMake(nameLabelX + 90, nameLabelY, nameLabelW + 100, nameLabelH)]; 32 33 nameBackLabel.backgroundColor = [UIColor yellowColor]; 34 35 nameBackLabel.text = @"请输入用户名"; 36 37 nameBackLabel.textAlignment = NSTextAlignmentCenter; 38 39 [self.window addSubview:nameBackLabel]; 40 41 //密码后面的label 42 UILabel *pswBackLabel = [[UILabel alloc] initWithFrame:CGRectMake(nameLabelX + 90, nameLabelY + 50, nameLabelW + 100, nameLabelH)]; 43 44 pswBackLabel.backgroundColor = [UIColor yellowColor]; 45 46 pswBackLabel.text = @"请输入密码"; 47 48 pswBackLabel.textAlignment = NSTextAlignmentCenter; 49 50 [self.window addSubview:pswBackLabel];
当然还有一些美化的属性代码
//label边角变圆 pswBackLabel.layer.cornerRadius = 20; //边框颜色 pswBackLabel.layer.borderColor = [UIColor redColor].CGColor; //边框宽度 pswBackLabel.layer.borderWidth = 5; //label显示内容的行数 0代表没有限制,其他数几就是几行 pswBackLabel.numberOfLines = 0;
恩,大致常用的就这些了,还有想加的属性的话可以百度搜,有许多大神会发,学无止境
