iOS7 사용자 지정 단추가 강조 표시 될 때 투명하게 됨

Question

iOS6 및 이전 단추처럼 보이는 사용자 지정 단추를 만들었지 만 iOS7에서 내 CustomButton은 강조 표시 될 때 투명하게 바뀝니다. 속성 adjustsImageWhenHighlighted를 NO로 설정하려고했지만 아무 것도 변경되지 않습니다. [self setAlpha : 1.f]도 작동하지 않습니다.

다음, 내 init 메소드 :

-(void) baseInit:(CGRect)frame :(CGFloat *)colorsNormal :(CGFloat *)colorsHighlighted :(CGFloat *)colorsDisabled 
{ 

    self.layer.borderWidth=1.0f; 
    self.layer.borderColor=[[UIColor colorWithRed:0.67f green:0.67f blue:0.67f alpha:1.0f] CGColor]; 
    self.layer.cornerRadius=7.0f; 

    self.clipsToBounds = YES; 

    UIImage *image = [self generateUIImageWithGradient:frame :colorsNormal]; 
    [self setBackgroundImage:image forState:UIControlStateNormal]; 
    [self setTitleColor:[UIColor colorWithRed:0.22f green:0.33f blue:0.53f alpha:1.0f] forState:UIControlStateNormal]; 

    UIImage *image2 = [self generateUIImageWithGradient:frame :colorsHighlighted]; 
    [self setBackgroundImage:image2 forState:UIControlStateHighlighted]; 
    [self setTitleColor:[UIColor colorWithRed:1.0f green:1.0f blue:1.0f alpha:1.0f] forState:UIControlStateHighlighted]; 

    UIImage *image3 = [self generateUIImageWithGradient:frame :colorsDisabled]; 
    [self setBackgroundImage:image3 forState:UIControlStateDisabled]; 
} 

-(id) generateUIImageWithGradient:(CGRect)frame :(CGFloat *)colors 
{ 
    CGSize size = CGSizeMake(frame.size.width, frame.size.height); 
    UIGraphicsBeginImageContextWithOptions(size, NO, 0); 
    CGContextRef context = UIGraphicsGetCurrentContext(); 

    CGColorSpaceRef colorspace = CGColorSpaceCreateDeviceRGB(); 

    size_t gradientNumberOfLocations = 2; 
    CGFloat gradientLocations[2] = {0.0, 1.0}; 

    CGGradientRef gradient = CGGradientCreateWithColorComponents(colorspace, colors, gradientLocations, gradientNumberOfLocations); 

    CGContextDrawLinearGradient(context, gradient, CGPointMake(0, 0), CGPointMake(0, size.height), 0); 

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); 

    CGGradientRelease(gradient); 
    CGColorSpaceRelease(colorspace); 
    UIGraphicsEndImageContext(); 

    return image; 
} 

그리고 내 메서드 호출 : iOS7에에 iOS6의에 매력과 NormalState 일처럼 작동

CGFloat colorsNormal [] = {1.0f,1.0f,1.0f,1.0f,1.0f,1.0f,1.0f,1.0f}; 
CGFloat colorsHighlighted [] = {0.03f,0.55f,0.97f,1.0f,0.0f,0.37f,0.90f,1.0f}; 
CGFloat colorsDisabled [] = {1.0f,1.0f,1.0f,1.0f,1.0f,1.0f,1.0f,1.0f}; 

[self baseInit:rect :colorsNormal :colorsHighlighted :colorsDisabled];

덕분에 작동하는 것. 문제 해결됨.
