Out of range crash #19
Description
I was getting a range exception on longer strings. I fixed it by adding checks for range in the main class and its string category
//tomsmorphinglabel Line 342
if (range.location + range.length < aString.length) {
NSString *character = [aString substringWithRange:range];
CGSize characterSize = CGSizeZero;
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
#ifdef PRECISE_FONT_METRICS
#define CFAutomatedReferenceCount(CFAnyTypeRef, typeRef, CFCreateOrCopyFunction) CFAnyTypeRef typeRef = ((__bridge CFAnyTypeRef)CFBridgingRelease(CFCreateOrCopyFunction))
@autoreleasepool {
UIFont *font = attributionStage[NSFontAttributeName];
CFAutomatedReferenceCount(CTFontRef, fontRef, CTFontCreateWithName((__bridge CFStringRef)font.fontName, font.pointSize, NULL));
CFAutomatedReferenceCount(CFAttributedStringRef, attributed, CFAttributedStringCreate(NULL, (__bridge CFStringRef)character, (__bridge CFDictionaryRef)@{(id)kCTFontAttributeName : (__bridge id)fontRef}));
