1、UITextField的使用
//初始化
self.txtName=[[UITextField alloc] initWithFrame:CGRectMake(100, 20, 200, 50)];
//添加背景颜色
self.txtName.backgroundColor=[UIColor redColor];
//文本框的边框线型
self.txtName.borderStyle=UITextBorderStyleLine;
//编辑文本框的提示，在键盘中输入文字时，“请输入姓名”会自动消失
self.txtName.placeholder=@"请输入姓名";
//把txtName添加到view上
[self.view addSubview:self.txtName];
//手动编辑文本框
self.txtName.text=@"123456";
//设置文本框字体的颜色
self.txtName.textColor=[UIColor purpleColor];
//设置整体字体背景颜色
NSMutableAttributedString *str=[[NSMutableAttributedString alloc] initWithString:@"lamco" attributes:@{NSBackgroundColorAttributeName:[UIColor redColor]}];
[str addAttributes:@{NSBackgroundColorAttributeName:[UIColor grayColor]}range:NSMakeRange(2, 3)] ;
[str addAttributes:@{NSForegroundColorAttributeName:[UIColor blackColor]} range:NSMakeRange(0, 3)];
self.txtName.attributedText=str;
self.txtName.returnKeyType=UIReturnKeySearch;
self.txtName.keyboardType=UIKeyboardTypePhonePad;
2.键盘的隐藏于弹出方法
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
if ([textField isFirstResponder]) {
[textField resignFirstResponder];
}
return YES;
}
3.UISegmentedControl的使用
//设置Segment的显示项
self.mySegment=[[UISegmentedControl alloc] initWithItems:@[@"red",@"green",@"blue"]];
//设置默认选中项
self.mySegment.selectedSegmentIndex=1;
//添加项
[self.mySegment insertSegmentWithTitle:@"yellow" atIndex:3 animated:YES];
//设置位置
self.mySegment.frame=CGRectMake(100, 100, 200, 30);
//把mySegment添加到父视图view中
[self.view addSubview:self.mySegment];
4.UIStepper的使用
self.myStepper=[[UIStepper alloc] initWithFrame:CGRectMake(100, 200, 100, 100)];
//设置最小值
self.myStepper.minimumValue=1.0;
//设置最大值
self.myStepper.maximumValue=10.0;
//设置每次所加的数
self.myStepper.stepValue=1.0;
//前景色
self.myStepper.tintColor=[UIColor redColor];
//设置循环
self.myStepper.wraps=YES;
[self.view addSubview:self.myStepper];
