Question

我能够给航道打上形象,并改变航条星子项目的形象。出于某种原因,导航条形图像,即gues,与导航条形图相重叠。航行驳船纽扣在左边的航标图上,但并未显示航标形象,因此运行正确。此处为法典;

UIImage *imagebar = [UIImage imageNamed: @"schedule-strip.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage: imagebar];
imageView.frame = CGRectMake(0, 0, 190, 44);
imageView.contentMode = UIViewContentModeScaleAspectFill;
self.navigationItem.titleView = imageView;


UIImage* image = [UIImage imageNamed:@"back-icon.png"];
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* someButton = [[UIButton alloc] initWithFrame:frame];
[someButton setBackgroundImage:image forState:UIControlStateNormal];
[someButton setShowsTouchWhenHighlighted:YES];
[someButton addTarget:self action:@selector(backToMore) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem* someBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:someButton];
[self.navigationItem setLeftBarButtonItem:someBarButtonItem];

[someBarButtonItem release];
[someButton release];

帮助我。

Answer 1

use the code [imageView addsubView someButton];

我希望现在就看到纽州。实际上,你正在把左条 bar子添加到停泊的航道上,并且作为制造一些布道的乌普车,并没有在座标上添加,而图像座标与你的航条相重叠。因此,通过点击该地区,它正在工作,但纽州并不明显。

Answer 2

- (void)drawRect:(CGRect)rect {
    UIImage *image = [UIImage imageNamed: @"TopBg.png"];
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
