iOS中自定义UIView(用接口获取Lable和TextFile中的值)

  NSArray *arrayText = @[@"用户名",@"密码",@"确认密码",@"手机号",@"邮箱"];

    NSArray *placeholders = @[@"请输入用户名",@"请输入密码",@"请确认密码",@"请输入手机号",@"请输入邮箱"];
    NSInteger y = 30;
    for (int i = 0; i < 5; i++) {

        LTView *aView = [[LTView alloc] initWithFrame:CGRectMake(30, y, 280, 35)];

        //aView.backgroundColor = [UIColor redColor];

        [aView setDesLabelText:arrayText[i]];
        [aView setPlacehloder:placeholders[i]];
        [self.window addSubview:aView];
        [aView setDelegate:self];

        [aView release];

        if (i == 1 || i ==2) {

            [aView setSecureTextType:YES];
        }

        if (i == 3) {
            [aView setKeyboardType:UIKeyboardTypeNumberPad];
        }
        y += 45;

    }

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeSystem];

    [btn setTitle:@"注册" forState:UIControlStateNormal];

    btn.frame = CGRectMake(50, 270, 100, 40);

    //btn.backgroundColor = [UIColor redColor];

    [view addSubview:btn];

    UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeSystem];

    [btn1 setTitle:@"取消" forState:UIControlStateNormal];

    btn1.frame = CGRectMake(170, 270, 100, 40);

    //btn1.backgroundColor = [UIColor redColor];
    [view addSubview:btn1];

    [btn addTarget:self action:@selector(zhuce) forControlEvents:UIControlEventTouchUpInside];

     [btn1 addTarget:self action:@selector(quit) forControlEvents:UIControlEventTouchUpInside];

    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
   }

- (void)quit
{
    //NSLog(@"-----");
  //UIView *view = [self.window viewWithTag:50];
//    for (int i = 0; i < 5; i++) {
//        UITextField *fil = (UITextField *)[view viewWithTag:(100 * i) + 100];
//        fil.text = @"";
//    }
    [self.window endEditing:YES];

}

- (void)zhuce
{
//     UIView *view = [self.window viewWithTag:50];
//    for (int i = 0; i < 5; i++) {
//        UITextField *fil = (UITextField *)[view viewWithTag:(100 * i) + 100];
//        fil.text = @"=-====顶你肺==";
//    }

}

LTView.h(自定义的UIView,定义接口)

@interface LTView : UIView

//LTView 属于自定义的视图(组合视图),携带有坐label,又textField,两个控件只有LTView能狗识别,因此需要LTView给外界提供操作label和textFiedld访问接口
//给label设置文字的接口

- (void)setDesLabelText:(NSString *)text;

//给textField设置提示文字
- (void)setPlacehloder:(NSString *)text;

//给txtField 设置键盘接口
- (void)setKeyboardType:(UIKeyboardType)keyboardType;

//给textField设置密码格式
- (void)setSecureTextType:(BOOL)secureTextType;

- (NSString *)text;

//给textField设置代理的接口
- (void)setDelegate:(id<UITextFieldDelegate>)delegate;

LTView.m(关键在重写initWithFrame方法)

#import "LTView.h"
@interface LTView ()
@property (nonatomic,retain) UILabel *desLabel;
@property (nonatomic,retain) UITextField *textField;
@end

@implementation LTView

重写从父类继承来的initWithFrame:方法,在自定义视图初始化的时候完成自身控件的创建

 */

        [self setDescLabelWithWidth:frame.size.width / 3 height:frame.size.height];
        //textField
        [self setPlacehodlTextFieldWithWidth:frame.size.width / 3 * 2 height:frame.size.height];
    }
    return self;
}

    [self addSubview:self.desLabel];

    [self.desLabel release];
