UIAppearance setTranslucent error: Illegal property type, c for appearance setter, _installAppearanceSwizzleForSetter

Question

Trying out iOS 7 did:

[[UINavigationBar appearance] setTranslucent:NO];

Got crash and error:

*** Terminating app due to          


        

Answer 1

I solved it with my own category so that I can still use UIAppearance in something like the normal manner.

@interface UINavigationBar (MMTranlucenceUIAppearance)
@property(nonatomic,assign,getter=isMMTranslucent) NSInteger LYTranslucent NS_AVAILABLE_IOS(3_0) UI_APPEARANCE_SELECTOR;  // Default is NO on iOS 6 and earlier. Always YES if barStyle is set to UIBarStyleBlackTranslucent
@end


@implementation UINavigationBar (MMTranlucenceUIAppearance)

// it appears that UIAppearance fails with BOOL
-(NSInteger)isMMTranslucent
{
    return self.translucent ? 0 : 1;
}

-(void)setMMTranslucent:(NSInteger)translucent
{
    self.translucent = (translucent == 0) ? NO : YES;
}

@end
