//设置显示文字 scoreLabel.text = @ "我是Andy--清风" ; //设置字体:粗体,正常的是 SystemFontOfSize,调用系统的字体配置 scoreLabel.font = [UIFont boldSystemFontOfSize:20]; //设置文字颜色,可以有多种颜色可以选择 scoreLabel.textColor = [UIColor orangeColor]; scoreLabel.textColor = [UIColor purpleColor]; //设置文字对齐位置,居左,居中,居右 scoreLabel.textAlignment = UITextAlignmentRight; scoreLabel.textAlignment = UITextAlignmentCenter; //设置字体大小是否适应label宽度 scoreLabel.adjustsFontSizeToFitWidth = YES; //设置label的行数,这个可以根据上节的UITextView自适应高度 scoreLabel.numberOfLines = 2; //设置文本是否高亮和高亮时的颜色 scoreLabel.highlighted = YES; scoreLabel.highlightedTextColor = [UIColor orangeColor]; //设置阴影的颜色和阴影的偏移位置 scoreLabel.shadowColor = [UIColor redColor]; scoreLabel.shadowOffset = CGSizeMake(1.0,1.0); //设置是否能与用户进行交互 scoreLabel.userInteractionEnabled = YES; //设置label中的文字是否可变,默认值是YES scoreLabel.enabled = NO; //设置文字过长时的显示格式 scoreLabel.lineBreakMode = UILineBreakModeMiddleTruncation; //截去中间 |

scoreLabel.backgroudColor=[UIColor clearColor];
之外你还可以使用自定义的颜色:
UIColor *color = [UIColor colorWithRed:1.0f green:50.0f blue:0.0f alpha:1.0f];
scoreLabel.textColor = [UIColor color]; |
//UIColor 里的 RGB 值是CGFloat类型的在0~1范围内,对应0~255的颜色值范围。

UITextField* text = [[UITextField alloc] initWithFrame:CGRectMake(10, 50, 300, 30)];
text.borderStyle = UITextBorderStyleRoundedRect;
text.autocorrectionType = UITextAutocorrectionTypeYes;
text.placeholder = @
"您好,我是Andy—清风"
;
text.returnKeyType = UIReturnKeyDone;
text.clearButtonMode = UITextFieldViewModeWhileEditing;
[text setBackgroundColor:[UIColor whiteColor]];
text.delegate = self;
[self.view addSubview:text];
|
borderStyle:文本框的边框风格
autocorrectionType:可以设置是否启动自动提醒更正功能。
placeholder:设置默认的文本显示
returnKeyType:设置键盘完成的按钮
backgroundColor:设置背景颜色
delegate:设置委托

//当textField编辑结束时调用的方法
//按下Done按钮的调用方法,我们让键盘消失
