我需要的东西就是这样的 http://anishusite.appspot.com/hbimgs/Bills220.png如何按钮添加到UINavigationBar的
能够改变从导航栏的日期......这怎么办呢? 我尝试添加与古都按钮的工具栏,并与日期标签的视图,但它不工作得很好

下面是代码:
//first create the view
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(0, 6, 157, 33)];
[titleView setBackgroundColor:[UIColor clearColor]];
//add the buttons to the view
UIButton *prevButton = [UIButton buttonWithType:UIButtonTypeCustom];
[prevButton setFrame:CGRectMake(0, 1, 32, 32)];
[prevButton setBackgroundImage:[UIImage imageNamed:@"36-circle-west"] forState:UIControlStateNormal];
[prevButton addTarget:self action:@selector(prevMonth) forControlEvents:UIControlEventTouchUpInside];
[titleView addSubview:prevButton];
UIButton *nextButton = [UIButton buttonWithType:UIButtonTypeCustom];
[nextButton setFrame:CGRectMake(145, 1, 32, 32)];
[nextButton setBackgroundImage:[UIImage imageNamed:@"20-circle-east"] forState:UIControlStateNormal];
[nextButton addTarget:self action:@selector(nextMonth) forControlEvents:UIControlEventTouchUpInside];
[titleView addSubview:nextButton];
[self.dateLabel setFrame:CGRectMake(33, 1, 90, 33)];
[self.dateLabel setBackgroundColor:[UIColor clearColor]];
[self.dateLabel setTextAlignment:UITextAlignmentCenter];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterNoStyle];
[dateFormatter setTimeStyle:NSDateFormatterNoStyle];
[dateFormatter setDateFormat:@"MMMM,YYYY"];
NSString *dateString = [dateFormatter stringFromDate:self.beginDate];
NSLog(@"the title date string: %@",dateString);
[self.dateLabel setText:dateString];
[self.dateLabel setTextColor:[UIColor whiteColor]];
[self.dateLabel setBackgroundColor:[UIColor clearColor]];
[self.dateLabel setFont:[UIFont fontWithName:@"System" size:17.0]];
//create the toolbar itself
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 240, 44)];
[toolbar setBackgroundColor:[UIColor clearColor]];
NSMutableArray *items = [NSMutableArray arrayWithCapacity:3];
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addTransaction)];
addButton.style = UIBarButtonItemStyleBordered;
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *theView = [[UIBarButtonItem alloc] initWithCustomView:titleView];
[items addObject:theView];
[items addObject:spacer];
[items addObject:addButton];
[toolbar setItems:items animated:NO];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];

正如你可以看到它看起来不太好。标签不显示...按钮似乎只有上半挖掘工作。 (当拍了拍方法称为OK)......任何ideeas? BTW导航栏有一个背景图像,但是在工具栏覆盖它。为什么?我有一个清晰的彩色背景制作工具栏....
什么不工作?您是否添加了方法来在您点击按钮后更改日期? – Josh
