IOS 自定义导航栏 和表格 学习笔记
demo 下载地址：http://download.csdn.net/detail/robinson_911/8349659
昨天花了点时间重新学习了下UITableView 和自定义导航栏，写了个demo以备后面查看。
先说昨天遇到的问题，
1.demo写完后，发现表格老是有重叠页面，同时表格的位置不能能够控制。最后发现原来是:
@interface SwwTableViewController :UITableView<UITableViewDelegate,UITableViewDataSource>
SwwTableViewController继承的是UITableView，所以会出现重叠页面，同时UITableView的位置也不能控制。
最后改为继承UIViewController后，就不会出现上面的情况了。
@interface SwwTableViewController :UIViewController<UITableViewDelegate,UITableViewDataSource>
2.自定义有标题栏的UITableView
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headView = [[[UIView alloc] init] autorelease];
[headView setFrame:CGRectMake(0, 100, 320, 30)];
headView.backgroundColor = [UIColor whiteColor];
// headView.backgroundColor = [UIColor groupTableViewBackgroundColor];
//边框2
UIView *borderView = [[UIView alloc] initWithFrame:CGRectMake(10, 30, 300, 1)];
borderView.layer.backgroundColor = [[UIColor grayColor] CGColor];
borderView.layer.borderWidth = 1.0f;
[headView addSubview:borderView];
[borderView release];
UILabel *_orderLable = [self _generateHintLabel];
[_orderLable setFrame:CGRectMake(3, headerHight, 60, 20)];
[headView addSubview:_orderLable];
UILabel *_productLable = [self _generateHintLabel];
[_productLable setFrame:CGRectMake(60, headerHight, 60, 20)];
[headView addSubview:_productLable];
UILabel *_doLable = [self _generateHintLabel];
[_doLable setFrame:CGRectMake(125, headerHight, 60, 20)];
[headView addSubview:_doLable];
UILabel *_buyTimeLable = [self _generateHintLabel];
[_buyTimeLable setFrame:CGRectMake(165, headerHight, 60, 20)];
[headView addSubview:_buyTimeLable];
UILabel *_buyMoneyLable = [self _generateHintLabel];
[_buyMoneyLable setFrame:CGRectMake(240, headerHight, 60, 20)];
[headView addSubview:_buyMoneyLable];
//第一个section的标题栏
if ( section == 0 )
{
_orderLable.text = @"订单号";
_productLable.text = @"产品名称";
_doLable.text = @"操作";
_buyTimeLable.text = @"购买时间";
_buyMoneyLable.text = @"购买金额";
}
return headView;
}
3.自定义导航栏
//方法一 自定义导航栏
UINavigationBar *_navigationBar = [[UINavigationBar alloc] init];
_navigationBar.frame = CGRectMake(0, 20, MAIN_SCREEN_WIDTH, 44);
_navigationBar.backgroundColor = [UIColor redColor];
[self.view addSubview:_navigationBar];
UILabel *titleText = [[UILabel alloc] initWithFrame: CGRectMake(0, 0, MAIN_SCREEN_WIDTH, 44)];
// titleText.backgroundColor = [UIColor clearColor];
titleText.textColor=[UIColor blackColor];
[titleText setFont:[UIFont systemFontOfSize:14.0]];
titleText.textAlignment = NSTextAlignmentCenter;
titleText.text =@"导航栏Demo";
[_navigationBar addSubview:titleText];
UINavigationItem *navigationItem = nil;
UIButton *button = [UIButton buttonWithType: UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"top_icon_back"] forState:UIControlStateNormal];
button.backgroundColor = [UIColor clearColor];
button.frame = CGRectMake(0, 6, 49, 31);
//[button setTitle:@"返回" forState:UIControlStateNormal];
[_navigationBar addSubview:button];
//方法二 自定义导航栏
UIButton *setingBtn = [UIButton buttonWithType:UIButtonTypeCustom];
setingBtn.frame = CGRectMake(0, 6, 49, 31);
[setingBtn setBackgroundImage:[UIImage imageNamed:@"top_icon_back"]
forState:UIControlStateNormal];
setingBtn.backgroundColor = [UIColor clearColor];
//创建一个导航栏
UINavigationBar *navigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 20, 320, 44)];
navigationBar.backgroundColor = [UIColor redColor];
//创建一个导航栏集合
UINavigationItem *navigationItem = [[UINavigationItem alloc] initWithTitle:nil];
//创建一个左边按钮
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"返回"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(clickLeftButton)];
//创建一个右边按钮
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"下一页"
style:UIBarButtonItemStyleDone
target:self
action:@selector(clickRightButton)];
//设置导航栏内容
[navigationItem setTitle:@"导航栏Demo"];
//1 .把导航栏集合添加入导航栏中，设置动画关闭
// [navigationBar pushNavigationItem:navigationItem animated:NO];
//2.把导航栏集合添加入导航栏中
[navigationBar setItems: [NSArray arrayWithObject: navigationItem]];
//把左右两个按钮添加入导航栏集合中
// [navigationItem setLeftBarButtonItem:leftButton];
navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:setingBtn] autorelease];
[navigationItem setRightBarButtonItem:rightButton];
//把导航栏添加到视图中
[self.view addSubview:navigationBar];
//释放对象
[navigationItem release];
[leftButton release];
[rightButton release];
//方法三 自定义导航栏
UIButton *setingBtn = [UIButton buttonWithType:UIButtonTypeCustom];
setingBtn.frame = CGRectMake(200, 6, 49, 31);
[setingBtn setBackgroundImage:[UIImage imageNamed:@"top_icon_back"]
forState:UIControlStateNormal];
setingBtn.backgroundColor = [UIColor clearColor];
UIToolbar *myToolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 20, MAIN_SCREEN_WIDTH, 44)];
[self.view addSubview:myToolBar];
UIBarButtonItem *bn1 = [[UIBarButtonItem alloc]
initWithTitle:@"OK"
style:UIBarButtonItemStylePlain
target:nil
action:nil] ;
UIBarButtonItem *bn3 = [[UIBarButtonItem alloc]initWithCustomView :setingBtn];
[myToolBar setItems:[NSArray arrayWithObjects:bn1,bn3, nil]];
UILabel *titleText = [[UILabel alloc] initWithFrame: CGRectMake(0, 0, MAIN_SCREEN_WIDTH, 44)];
// titleText.backgroundColor = [UIColor clearColor];
titleText.textColor=[UIColor blackColor];
[titleText setFont:[UIFont systemFontOfSize:14.0]];
titleText.textAlignment = NSTextAlignmentCenter;
titleText.text =@"导航栏Demo";
[myToolBar addSubview:titleText];
