UI总结-导航控制器NavigationController

今天回顾了一下导航控制器NavigationController,下面是具体代码:

#import "ViewController.h"

#import "SecondViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

self.view.backgroundColor = [UIColor whiteColor];

//设置导航试图控制器的外观样式

//下面的这个属性是设置导航控制器是否为半透明,这个属性会影响试图的坐标系:默认情况是半透明,试图的起点坐标是从屏幕的左上角开始的,当设置为透明,起点坐标是在导航控制器下面的左上角开始的.

self.navigationController.navigationBar.translucent = NO;

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];

view.backgroundColor = [UIColor redColor];

[self.view addSubview:view];

[view release];

//修改导航控制器的颜色

self.navigationController.navigationBar.barTintColor = [UIColor cyanColor];

//修改里面的内容

//self.title = @"school";

//self.navigationItem.title = @"class";

UISegmentedControl *seg = [[UISegmentedControl alloc]initWithItems:@[@"消息",@"通知"]];

self.navigationItem.titleView = seg;

//创建导航控制器左右两边的按钮

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"title" style:UIBarButtonItemStylePlain target:self action:@selector(barAction)];

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

[button setImage:[UIImage imageNamed:@"pinglun.png"] forState:UIControlStateNormal];

button.frame = CGRectMake(0, 0, 40, 40);

self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc]initWithCustomView:button] autorelease];

UIButton * btn = [UIButton buttonWithType:UIButtonTypeCustom];

btn.frame = CGRectMake(100, 100, 100, 100);

btn.backgroundColor = [UIColor redColor];

[self.view addSubview:btn];

[btn setTitle:@"下一页" forState:UIControlStateNormal];

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

}

-(void)barAction{

}

-(void)click:(UIButton *)button{

SecondViewController *vc = [[SecondViewController alloc]init];

[self.navigationController pushViewController:vc animated:YES];

[vc release];

}

运行结果如下:
