用IOS做一个界面切换的效果(登录界面和注册界面和找回密码界面的切换)(用封装好的lable和textf创建界面)

来源：互联网发布：网络层协议包括编辑：程序博客网时间：2024/05/18 05:00

创建一个类封装uitextfield和UIlabel (源代码.m文件)

#import "TLView.h"

@interface TLView ()

{

UILabel *_desLabel; //左边的lable

UITextField *_textField;//右边的

}

@end

@implementation TLView

//改写父类的初始化方法,处理相同的性能

- (id)initWithFrame:(CGRect)frame

{

self = [superinitWithFrame:frame];

if (self) {

// Initialization code

CGFloat width = frame.size.width;

CGFloat height = frame.size.height;

//UIlabel

_desLabel = [[UILabelalloc] initWithFrame:CGRectMake(0,0, 0.3 * width, height)];

_desLabel.font = [UIFontsystemFontOfSize:18];

_desLabel.textAlignment =NSTextAlignmentRight;

// _desLabel.backgroundColor = [UIColor lightGrayColor];

[self addSubview:_desLabel];

[_desLabel release];

//UITextfield

_textField = [[UITextFieldalloc] initWithFrame:CGRectMake(0.4 * width,0 , 0.6 * width , height)];

_textField.borderStyle =UITextBorderStyleRoundedRect;

// _textField.backgroundColor = [UIColor lightGrayColor];

_textField.autocorrectionType =UITextAutocorrectionTypeNo;

[self addSubview:_textField];

[_textField release];

}

return self;

}

//改写初始化方法,处理不同的部分

- (id)initWithFrame:(CGRect)frame labelText:(NSString *)labelText placeholder:(NSString *)placeholder textFieldText:(NSString *)textFieldText{

self = [selfinitWithFrame:frame];

if (self) {

//initialization code here..

_desLabel.text = labelText; //

_textField.placeholder = placeholder;

_textField.text = textFieldText;

}

return self;

}

//填写各种方法,处理不同的部分

//1,是否采用安全模式

- (void)setSecureEntry:(BOOL)secureEntry{

_textField.secureTextEntry = secureEntry;

}

//2,设置键盘类型;

- (void)setKeyBoardType:(UIKeyboardType)keyBoardType{

_textField.keyboardType = keyBoardType;

}

//3,设置textField代理

- (void)setDelegate:(id<UITextFieldDelegate>)delegate{

_textField.delegate = delegate;

}

//4,获取输入框中的文字

- (NSString *)text{

return_textField.text;

}
