自定义UIButton与图像

Question

我想设置单元格的配件视图是UIButton。但没有显示。

下面是代码

UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom]; 
[accessory setImage:[UIImage imageNamed:@"plus.png"] forState:UIControlStateNormal]; 
[cell setAccessoryView:accessory]; 

Answer 1

呼叫[accessory sizeToFit];根据图像来调整其大小。

Answer 2

您将需要一个框架设置为此附件这样

UIButton *accessory = [UIButton buttonWithType:UIButtonTypeCustom]; 
[accessory setImage:[UIImage imageNamed:@"plus.png"] forState:UIControlStateNormal]; 
//Set the accessory frame 
accessory.frame = CGRectMake(0, 0, 100, 100); 

Answer 3

UIView* accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 24, 50)]; 
UIImageView* accessoryViewImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"arrow.png"]]; 
accessoryViewImage.center = CGPointMake(12, 25); 
[accessoryView addSubview:accessoryViewImage]; 
[cell setAccessoryView:accessoryView]; 
[accessoryViewImage release]; 
[accessoryView release]; 

只是做这样的。
