IOS基本孔控件(UIView UITextField UILable UIButton,控件组合,分类)

UIView

    //视图使用UIVIEW类来表示,UIVIEW是系统已提供好的类,可以拿来直接使用,UIVIEW在UIKIt框架里面.
    //第一步 创建视图(此刻不会显示)
    UIView *aView=[[UIView alloc]initWithFrame:CGRectMake(40, 70, 240, 240)];
    //第二部 添加到window上进行显示
    [self.window addSubview:aView];
    //第三步 视图进行相关设置(UIVIEW 默认是 透明色也就是clearColor)
    [aView setBackgroundColor:[UIColor blueColor]];
    aView.backgroundColor=[UIColor clearColor];
    aView.layer.borderWidth=5;
    aView.layer.cornerRadius=120;
    //第四部 内存管理(释放)
    [aView release];
    
    /*学习要讲究方法,流程性的东西最有指导性作用的.上面列出 了所有MVC中V使用流程.记得流程胜过背代码*/
    //MVC里的V一般不提供便利构造器方法,只提供初始化方法.
    //子视图以父视图坐标为原点
    //同为子视图后加在前面(子视图加在父视图前面)
    UIView * userView=[[UIView alloc]initWithFrame:CGRectMake(20, 50, 50, 30)];
    userView.backgroundColor=[UIColor clearColor];
    userView.layer.borderWidth=1;
    userView.layer.cornerRadius=10;
    [aView  addSubview:userView];
    [userView release];



UILable

    UILabel用于显示文本的控件 集成于uiview.相比uiview ,uilable类添加了空间的外观,提供了显示文字的功能
    使用UI步骤
    1.创建控件(alloc 初始化)
    注意:只要是空间,都需要设置frame  2.优先使用本类的初始化方法,如果没有,使用父类继承过初始化方法,以此类推.
    UILabel *useNameLable=[[UILabel alloc]initWithFrame:CGRectMake(30, 230, 70, 25)];
    
//    2.对控件进行设置(枚举值 自己试试)
    useNameLable.backgroundColor=[UIColor clearColor];
//    useNameLable.font=[UIFont italicSystemFontOfSize:20];
    useNameLable.layer.borderWidth=1;
    useNameLable.layer.cornerRadius=4;
    useNameLable.text=@" 用户名:";//    _useNameText=[[UITextField alloc]initWithFrame:CGRectMake(120, 230, 130, 25)];

//    3.添加到父视图
    [loginContainerView addSubview:useNameLable];
//    4.释放

    [useNameLable release];
    


UITextFild
//定义成属性
//    _useNameText=[[UITextField alloc]initWithFrame:CGRectMake(120, 230, 130, 25)];

//    _useNameText.backgroundColor=[UIColor clearColor];
//    [loginContainerView addSubview:_useNameText];
//    _useNameText.layer.borderWidth=1;
//    _useNameText.layer.cornerRadius=4;
//    //指定输入框占位
//    _useNameText.placeholder=@"请输入用户名";
//    //输入为大写或首字母大写等等
//    _useNameText.autocapitalizationType=UITextAutocapitalizationTypeAllCharacters;
//    //是否自动纠正
//    _useNameText.autocorrectionType=UITextAutocorrectionTypeYes;
//    //useNameText.borderStyle=[UITextBorderStyleRoundedRect];
//    //改变样式
//    _useNameText.borderStyle=UITextBorderStyleRoundedRect;
//    _useNameText.delegate=self;


//定义一个passWordText属性
//    _passWordText=[[UITextField alloc]initWithFrame:CGRectMake(120, 280, 130, 25)];
//    _passWordText.backgroundColor=[UIColor clearColor];
//    [loginContainerView addSubview:_passWordText];
//    _passWordText.layer.borderWidth=1;设置边框
//    _passWordText.layer.cornerRadius=4;//设置圆角
//    _passWordText.adjustsFontSizeToFitWidth=10;
//    _passWordText.placeholder=@"请输入密码";
//    _passWordText.secureTextEntry=YES;//设置输入的文字显示为圆点,
//    _passWordText.delegate=self;//代理


UIButton
初始化
//    UIButton * confirmButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
//    confirmButton.frame=CGRectMake(30,350 , 50, 20);
设置属性
//    confirmButton.backgroundColor=[UIColor clearColor];
//    [loginContainerView addSubview:confirmButton];
    confirmButton.backgroundColor=[UIColor orangeColor];
//    [confirmButton setTitle:@"登陆" forState:UIControlStateNormal];
//    confirmButton.layer.borderWidth=1;
//    confirmButton.layer.cornerRadius=4;
    [confirmButton setTitle:@"login" forState:UIControlStateHighlighted];//添加事件
//    [confirmButton addTarget:self action:@selector(login) forControlEvents:UIControlEventTouchUpInside];





下面是写了一些组合控件

UIlable和UITextField组合
@interface CustomTextField : UIView <UITextFieldDelegate>
@property(nonatomic ,strong)UILabel *descriptionlable;
@property(nonatomic,strong)UITextField *textField;

-(id)initWithFrame:(CGRect)frame description:(NSString *)description textField:(NSString *)textField;

@end

.m文件
-(id)initWithFrame:(CGRect)frame description:(NSString *)description textField:(NSString *)textField;
{
    self = [super initWithFrame:frame];
    if (self) {
        
        CGFloat width=frame.size.width;
        CGFloat height=frame.size.height;
        _descriptionlable=[[UILabel alloc]initWithFrame:CGRectMake(0, 0, width/3, height)];
        _descriptionlable.textAlignment=NSTextAlignmentRight;
        _descriptionlable.backgroundColor=[UIColor grayColor];
        _descriptionlable.text=description;
        _descriptionlable.layer.borderWidth=1;
        _descriptionlable.layer.cornerRadius=5;
        _descriptionlable.alpha=0.6;
        
        [self addSubview:_descriptionlable];
        _textField=[[UITextField alloc]initWithFrame:CGRectMake(width/3, 0, width-width/3, height)];
        _textField.borderStyle=UITextBorderStyleRoundedRect;
        _textField.text=textField;
        _textField.alpha=0.6;
       _textField.backgroundColor=[UIColor grayColor];
        _textField.layer.borderWidth=1;
        _textField.layer.cornerRadius=5;
        _textField.delegate=self;
        [self addSubview:_textField];
        
        // Initialization code
    }
    return self;
}



UIButoon分类
@interface UIButton (CategoryButton)
+ (UIButton *)roundRectButtonWithFrame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action;

+ (UIButton *)buttonWithType:(UIButtonType)type frame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action;
@end



#import "UIButton+CategoryButton.h"

@implementation UIButton (CategoryButton)
+ (UIButton *)roundRectButtonWithFrame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action
{
    
    return [UIButton buttonWithType:UIButtonTypeRoundedRect frame:frame title:title target:target action:action];
    
}

+ (UIButton *)buttonWithType:(UIButtonType)type frame:(CGRect)frame title:(NSString *)title target:(id)target action:(SEL)action
{
    UIButton *button = [UIButton buttonWithType:type];
    button.frame = frame;
    [button setTitle:title forState:UIControlStateNormal];
    [button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
    button.layer.borderWidth=1;
    button.layer.contentsScale=1;
    return button;
    
}
@end
