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 可能出了什么问题?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,即使在内存分配之后,所有 uiimage 变量也显示内存地址 0*000000000
注意::ScrollView1 工作正常,“image.jpg”是正确的参数。
最佳答案
[UIImage imageNamed:@"image.jpg"];
尝试这样。这会对你有帮助。
已编辑:
NSString *path = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"jpg"];
scrollView1.backgroundColor = [[UIColor alloc] initWithPatternImage:[[UIImage alloc] initWithContentsOfFile:path]];
