我寫這個方法爲我的項目 - SUITextView with highlight:
- (NSMutableAttributedString*) setColor:(UIColor*)color word:(NSString*)word inText:(NSMutableAttributedString*)mutableAttributedString {
NSUInteger count = 0, length = [mutableAttributedString length];
NSRange range = NSMakeRange(0, length);
while(range.location != NSNotFound)
{
range = [[mutableAttributedString string] rangeOfString:word options:0 range:range];
if(range.location != NSNotFound) {
[mutableAttributedString setTextColor:color range:NSMakeRange(range.location, [word length])];
range = NSMakeRange(range.location + range.length, length - (range.location + range.length));
count++;
}
}
return mutableAttributedString;
}
在我NSMutableAttributedString的類別:
- (void) setTextColor:(UIColor*)color range:(NSRange)range {
// kCTForegroundColorAttributeName
[self removeAttribute:(NSString*)kCTForegroundColorAttributeName range:range]; // Work around for Apple leak
[self addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)color.CGColor range:range];
}
完美也於2012年:) – NDY 2012-10-31 09:56:50
更簡單的方法,我認爲有一個額外的「}」左右浮動,但在'14 – dacopenhagen 2014-08-25 23:46:56
