Używam Core Text do dodawania tekstu do treści UITableviewCell, ale arabska treść wydaje się nakładać na siebie i powtarzać się, gdy przewijam i nakładam na inne komórki.

Używam także innych elementów na stronie, które wyglądają dobrze i nie powtarzają się. Just the Core Text wydaje się powtarzać.

Nie rozumiem dlaczego.

Oto mój kod:

     - (CTFontRef)newCustomFontWithName:(NSString *)aFontName
                            ofType:(NSString *)type
                        attributes:(NSDictionary *)attributes {
    NSString *fontPath = [[NSBundle mainBundle] pathForResource:aFontName ofType:type];

    NSData *data = [[NSData alloc] initWithContentsOfFile:fontPath];
    CGDataProviderRef fontProvider = CGDataProviderCreateWithCFData((__bridge CFDataRef)data);


    CGFontRef cgFont = CGFontCreateWithDataProvider(fontProvider);
    CGDataProviderRelease(fontProvider);

    CTFontDescriptorRef fontDescriptor = CTFontDescriptorCreateWithAttributes((__bridge CFDictionaryRef)attributes);
    CTFontRef font = CTFontCreateWithGraphicsFont(cgFont, 0, NULL, fontDescriptor);
    CFRelease(fontDescriptor);
    CGFontRelease(cgFont);
    return font;
}

- (CATextLayer *)customCATextLayer:(NSString *)textString {
    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                [NSNumber numberWithFloat:24.f], (NSString *)kCTFontSizeAttribute,
                                [NSNumber numberWithInt:1], (NSString *)kCTLigatureAttributeName,
                                nil];

    CTFontRef font = [self newCustomFontWithName:@"me_quranKer6"
                                          ofType:@"ttf"
                                      attributes:attributes];

    CATextLayer *normalTextLayer = [[CATextLayer alloc] init];
    normalTextLayer.font = font;
    normalTextLayer.string = textString;
    normalTextLayer.wrapped = YES;
    normalTextLayer.foregroundColor = [[UIColor blackColor] CGColor];
    normalTextLayer.fontSize = 24.f;
    normalTextLayer.alignmentMode = kCAAlignmentCenter;
    normalTextLayer.frame = CGRectMake(0.f, 10.f, 320.f, 32.f);

    CFRelease(font);
    return normalTextLayer;
}
