的UIImage不加載圖像

Question

下面的代碼工作很好..

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]; 

但這個不是......

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]; 

可能是什麼毛病的UIImage？在我的整個項目的UIImage不工作的任何地方....

在我所有的調試變量的UIImage顯示內存地址0 * 000000000即使在內存分配

注:: ScrollView1做工精細和「image.jpg的」是正確的論據。

Answer 1

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

試試這個。這對你有幫助。

編輯：

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