ios - UIImage 不加载图像

Question

以下代码工作正常..

scrollView1 = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 200, 1024, 200)];
scrollView1.contentSize = CGSizeMake(2048, 200);
scrollView1.showsHorizontalScrollIndicator = YES;
scrollView1.scrollEnabled = YES;
scrollView1.userInteractionEnabled = YES;
scrollView1.backgroundColor = [[UIColor alloc] initWithRed:0.5 green:0.8 blue:0.5 alpha:1];
[self.view addSubview:scrollView1];

但是这个不是……

scrollView1 = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 200, 1024, 200)];
scrollView1.contentSize = CGSizeMake(2048, 200);
scrollView1.showsHorizontalScrollIndicator = YES;
scrollView1.scrollEnabled = YES;
scrollView1.userInteractionEnabled = YES;
scrollView1.backgroundColor = [[UIColor alloc] initWithPatternImage:[[UIImage alloc] initWithContentsOfFile:@"image.jpg"]];
[self.view addSubview:scrollView1];

UIImage 可能有什么问题？在我的完整项目中 UIImage 无法在任何地方工作......

在我的调试器中，所有 uiimage 变量都显示内存地址 0*000000000 即使在内存分配之后

注意：：ScrollView1 工作正常，“image.jpg”是正确的参数。

Answer 1

[UIImage imageNamed:@"image.jpg"];

像这样试试。这将对您有所帮助。

编辑：

NSString *path = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"jpg"];
scrollView1.backgroundColor = [[UIColor alloc] initWithPatternImage:[[UIImage alloc] initWithContentsOfFile:path]];
