用IOS做一個界面切換的效果(登錄界面和注冊界面和找回密碼界面的切換)(用封裝好的lable和textf創建界面)

編輯:IOS開發綜合

創建一個類封裝uitextfield和UIlabel (源代碼.m文件)

#import "TLView.h"

@interface TLView ()

{

UILabel *_desLabel; //左邊的lable

UITextField *_textField;//右邊的

}

@end

@implementation TLView



//改寫父類的初始化方法,處理相同的性能

- (id)initWithFrame:(CGRect)frame

{

self = [super initWithFrame:frame];

if (self) {

// Initialization code

CGFloat width = frame.size.width;

CGFloat height = frame.size.height;

//UIlabel

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

_desLabel.font = [UIFont systemFontOfSize:18];

_desLabel.textAlignment = NSTextAlignmentRight;

// _desLabel.backgroundColor = [UIColor lightGrayColor];

[self addSubview:_desLabel];

[_desLabel release];

//UITextfield

_textField = [[UITextField alloc] 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;

}

//改寫初始化方法,處理不同的部分

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

self = [self initWithFrame:frame];

if (self) {

//initialization code here..

_desLabel.text = labelText; //

_textField.placeholder = placeholder;

_textField.text = textFieldText;

}

return self;

}



//填寫各種方法,處理不同的部分

//1,是否采用安全模式

- (void)setSecureEntry:(BOOL)secureEntry{

_textField.secureTextEntry = secureEntry;

}

//2,設置鍵盤類型;

- (void)setKeyBoardType:(UIKeyboardType)keyBoardType{

_textField.keyboardType = keyBoardType;

}

//3,設置textField代理

- (void)setDelegate:(id)delegate{

_textField.delegate = delegate;

}

//4,獲取輸入框中的文字

- (NSString *)text{

return _textField.text;

}
