NSMutableRLEArray objectAtIndex:effectiveRange:: Out of bounds

current += 1;

while (effectRange.location + effectRange.length < targetRange.location + targetRange.length) {
NSInteger current = effectRange.location + effectRange.length;
if (current <= last) {
current += 1;
}
NSDictionary *attributes = [textStorage attributesAtIndex:current effectiveRange:&effectRange];

这样处理，是否可能出现current > textStorage..mutableString.length，导致越界呀？要做保护的话，可以是
NSInteger current = effectRange.location + effectRange.length;
while (current < targetRange.location + targetRange.length) {
NSDictionary *attributes = [textStorage attributesAtIndex:current effectiveRange:&effectRange];
if (attributes) {
NSParagraphStyle *style = attributes[NSParagraphStyleAttributeName];
lineSpacing = MAX(lineSpacing, style.lineSpacing);
}
last = current;

        current = effectRange.location + effectRange.length;
        if (current <= last) {
            current += 1;
        }
    }

不知道对不对，因为现在遇到一个crash，没有复现，排查可能是这里的问题
