如何摆脱我的UIImage周围的黑色？

Question

如何摆脱我的UIImage周围的黑色？ （在下面链路示出）

UIView *myView = [[[UIView alloc] init] autorelease]; 
[myView setBackgroundColor:[UIColor clearColor]]; 
CCUIViewWrapper *wrapper = [CCUIViewWrapper wrapperForUIView:myView]; 

UIColor *background = [UIColor colorWithPatternImage:[UIImage imageNamed:@"alert_background.png"]]; 
myView.backgroundColor = background; 

wrapper.contentSize = CGSizeMake(293,180); 
wrapper.position = ccp(-90,190); 
[wrapper setRotation:90.0]; 

[self addChild:wrapper];

Answer 1

尝试视图的不透明值设置为NO

myView.opaque = NO; 

这意味着该视图预计不会填补其边界。
