UI自定义视图
将label和textField写成一个view
新建一个UIView子类
1 #import <UIKit/UIKit.h> 2 3 @interface LTView : UIView 4 { 5 // 写在实例变量里面外界不能访问 6 UILabel *_label; // 标签 7 UITextField *_textField; // 输入框 8 } 9 // 外界可访问 10 @property (nonatomic, copy) NSString *labelText; // 标签的文字 11 @property (nonatomic, retain) UIColor *lableTextColor; 12 @property (nonatomic, copy) NSString *textFieldText; 13 @property (nonatomic, assign, getter = isSecureTextEntry) BOOL secureTextEntry; // 设置是否以圆点方式显示 14 @property (nonatomic, assign) id<UITextFieldDelegate> delegate; 15 16 #pragma mark 初始化方法 17 - (instancetype)initWithFrame:(CGRect)frame withLabelText:(NSString *)text; 18 19 @end
实现部分
1 #import "LTView.h" 2 3 @implementation LTView 4 5 - (void)dealloc 6 { 7 [_label release]; 8 [_textField release]; 9 10 [super dealloc]; 11 } 12 13 #pragma mark 重写initWithFrame: 14 - (id)initWithFrame:(CGRect)frame 15 { 16 self = [super initWithFrame:frame]; 17 if (self) { 18 // self.backgroundColor = [UIColor cyanColor]; 19 20 // 添加Label 21 _label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, frame.size.width / 3, frame.size.height)]; 22 // _label.backgroundColor = [UIColor grayColor]; 23 [self addSubview:_label]; 24 25 // 添加TextField 26 _textField = [[UITextField alloc] initWithFrame:CGRectMake(frame.size.width / 3, 0, frame.size.width / 3 * 2, frame.size.height)]; 27 _textField.borderStyle = UITextBorderStyleRoundedRect; 28 [self addSubview:_textField]; 29 } 30 return self; 31 } 32 33 #pragma mark 重写setter和getter方法 34 - (void)setLabelText:(NSString *)labelText 35 { 36 _label.text = labelText; 37 } 38 - (NSString *)labelText 39 { 40 return _label.text; 41 } 42 43 - (void)setLableTextColor:(UIColor *)lableTextColor 44 { 45 _label.textColor = lableTextColor; 46 } 47 48 - (void)setTextFieldText:(NSString *)textFieldText 49 { 50 _textField.text = textFieldText; 51 } 52 - (NSString *)textFieldText 53 { 54 return _textField.text; 55 } 56 57 - (void)setSecureTextEntry:(BOOL)secureTextEntry 58 { 59 _textField.secureTextEntry = secureTextEntry; 60 } 61 - (BOOL)isSecureTextEntry 62 { 63 return _textField.secureTextEntry; 64 } 65 66 - (void)setDelegate:(id<UITextFieldDelegate>)delegate 67 { 68 _textField.delegate = delegate; 69 } 70 71 #pragma mark 实现初始化方法 72 - (instancetype)initWithFrame:(CGRect)frame withLabelText:(NSString *)text 73 { 74 self = [self initWithFrame:frame]; 75 if (self) { 76 _label.text = text; 77 } 78 return self; 79 } 80 81 @end
AppDelegate.m中
1 LTView *view = [[LTView alloc] initWithFrame:CGRectMake(30, 50, 200, 30) withLabelText:@"用户名"]; 2 view.delegate = self; 3 // view.SecureTextEntry = YES; 4 [self.window addSubview:view]; 5 [view release]; 6 7 LTView *view2 = [[LTView alloc] initWithFrame:CGRectMake(30, 100, 200, 30) withLabelText:@"密码"]; 8 view2.delegate = self; 9 view2.SecureTextEntry = YES; 10 [self.window addSubview:view2]; 11 [view2 release];
