自定义导航栏:
// CustomNaviBarView.h #import <UIKit/UIKit.h> @interface CustomNaviBarView : UIView { @private /** * 左侧按钮 */ UIButton* _leftButton; /** * 右侧按钮 */ UIButton* _rightButton; /** * 中部标签 */ UILabel* _navTitle; } @property(nonatomic,strong)UIButton* leftButton; @property(nonatomic,strong)UIButton* rightButton; @property(nonatomic,strong)UILabel* navTitle; /** * 返回一个自定义导航条 * * @param controller 控制器对象 * @param leftTitle 导航左侧文本,默认:@"取消" * @param rightTitle 导航右侧文本 * @param centerTitle 导航中部文本 * * @return 导航条对象 */ - (CustomNaviBarView*)initCustomNaviBarViewOnController:(UIViewController*)controller leftTitle:(NSString*)leftTitle rightTitle:(NSString*)rightTitle centerTitle:(NSString*)centerTitle; @end
// CustomNaviBarView.m #import "CustomNaviBarView.h" #import "Constant.h" @implementation CustomNaviBarView @synthesize leftButton = _leftButton; @synthesize rightButton = _rightButton; @synthesize navTitle = _navTitle; - (CustomNaviBarView*)initCustomNaviBarViewOnController:(UIViewController*)controller leftTitle:(NSString*)leftTitle rightTitle:(NSString*)rightTitle centerTitle:(NSString*)centerTitle { //1.创建导航栏视图 self = [super initWithFrame:CGRectMake(0, 0, WIDTH_SCREEN, 65)]; if (self != nil)//当导航视图没有加载成功的时候推出该方法 { //1.为导航视图设置背景 self.backgroundColor = [UIColor colorWithRed:248 / 255.0 green:248 / 255.0 blue:248 / 255.0 alpha:1]; [[controller navigationController] setNavigationBarHidden:YES animated:YES]; //2.导航面板左边的取消按钮 _leftButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; if (_leftButton != nil) { _leftButton.frame = CGRectMake(15, 20, 65, 44); if (leftTitle != nil) { [_leftButton setTitle:leftTitle forState: UIControlStateNormal]; }else { [_leftButton setTitle:POST_CANCEL_BUTTON forState: UIControlStateNormal]; } [_leftButton setTitleColor:[[UIColor alloc] initWithRed:0 green:158/255.0 blue:150/255.0 alpha:1.0]forState:UIControlStateNormal]; _leftButton.titleLabel.font = [UIFont systemFontOfSize: 16.0]; _leftButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; //[leftButton addTarget:self action:@selector(cancelButtonEventTouchUpInside)forControlEvents :UIControlEventTouchUpInside]; [self addSubview:_leftButton]; } //3.导航面板右边的发布按钮 _rightButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; if (_rightButton != nil) { [_rightButton setFrame:CGRectMake(WIDTH_SCREEN - 80, 20, 65, 44)]; if (_rightButton != nil) { [_rightButton setTitle:rightTitle forState: UIControlStateNormal]; }else { //[rightButton setTitle:POST_CANCEL_BUTTON forState: UIControlStateNormal]; } [_rightButton setTitleColor:[[UIColor alloc] initWithRed:0 green:158/255.0 blue:150/255.0 alpha:1.0]forState:UIControlStateNormal]; _rightButton.titleLabel.font = [UIFont systemFontOfSize: 16.0]; _rightButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight; //[rightButton addTarget:self action:@selector(postButtonEventTouchUpInside)forControlEvents :UIControlEventTouchUpInside]; [self addSubview:_rightButton]; } //4.导航面板中部文字 _navTitle = [[UILabel alloc] initWithFrame:CGRectMake(80, 20, WIDTH_SCREEN - 80 - 80, 44)]; if (_navTitle != nil) { [_navTitle setTextColor:[UIColor blackColor]]; if (centerTitle != nil) { _navTitle.text = centerTitle; }else { //navTitle.text = @""; } [_navTitle setTextAlignment:NSTextAlignmentCenter]; _navTitle.font = [UIFont systemFontOfSize:18.0]; [self addSubview:_navTitle]; } //5.在导航视图底添加分割线 UIView *navDividingLine = [[UIView alloc] init]; if (navDividingLine != nil) { navDividingLine.frame = CGRectMake(0, 20 + 44, WIDTH_SCREEN, 1); navDividingLine.backgroundColor = [UIColor colorWithRed:221 / 255.0 green:221 / 255.0 blue:221 / 255.0 alpha:1]; [self addSubview:navDividingLine]; } //6.往view增加导航栏 //[controller.view addSubview:navView]; } return self; } @end
如何使用:
//1.创建导航 CustomNaviBarView* customNaviBarView = [[CustomNaviBarView alloc] initCustomNaviBarViewOnController:self leftTitle: nil rightTitle:NEWADDRESS_ADD_TITLE centerTitle:NEWADDRESS_NAVIGATION_TITLE]; if (customNaviBarView != nil) { [customNaviBarView.leftButton addTarget:self action:@selector(cancelButtonEventTouchUpInside) forControlEvents:UIControlEventTouchUpInside]; [customNaviBarView.rightButton addTarget:self action:@selector(addButtonEventTouchUpInside) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:customNaviBarView]; }
自定义分割线:
#import <UIKit/UIKit.h> @interface CustomDividingLine : UIView /** * 创建一条分割线 * * @param frame 位置及大小 * @param color 背景色,如果为空默认:#f2f2f2 * * @return 新创建的分割线 */ - (CustomDividingLine*)initDividingLineWithFrame:(CGRect)frame color:(UIColor*)color; @end
#import "CustomDividingLine.h" @implementation CustomDividingLine /** * 创建一条分割线 * * @param frame 位置及大小 * @param color 背景色 * * @return 新创建的分割线 */ - (CustomDividingLine*)initDividingLineWithFrame:(CGRect)frame color:(UIColor*)color { //3.2.1分割线 self = [super init]; if (self != nil) { self.frame = frame; if (color != nil) { self.backgroundColor = color; } else { self.backgroundColor = [[UIColor alloc] initWithRed:242/255.0 green:242/255.0 blue:242/255.0 alpha:1.0]; } } return self; } @end
如何使用:
//3.分割线 CustomDividingLine* customDividingLine = [[CustomDividingLine alloc]initDividingLineWithFrame:CGRectMake(0, 65 + 100, WIDTH_SCREEN, 1) color:nil]; if (customDividingLine != nil) { [self.view addSubview:customDividingLine]; }
