【问题描述】:
-(UITableViewCell*) makeLikeCell
{
// Load the top-level objects from the custom cell XIB.
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"SpotlightLikesTableViewCell" owner: self options: nil];
// Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
UITableViewCell *cell = [topLevelObjects objectAtIndex:0];
NSString *likeText = [likesAndComments objectAtIndex: kLikeRow];
TTTAttributedLabel *likeLabel = [[[TTTAttributedLabel alloc] initWithFrame:CGRectZero] autorelease];
likeLabel = (TTTAttributedLabel*) [cell viewWithTag: kCaptionTag];
likeLabel.textColor = [UIColor blueColor];
likeLabel.lineBreakMode = UILineBreakModeWordWrap;
[likeLabel setFont: [UIFont fontWithName: @"Helvetica Neue" size: 10]];
[likeLabel setText: likeText afterInheritingLabelAttributesAndConfiguringWithBlock: ^NSAttributedString *(NSMutableAttributedString *mutableAttributedString) {
NSRange colorRange = [[mutableAttributedString string] rangeOfString: @" like this photo." options: NSCaseInsensitiveSearch];
[mutableAttributedString addAttribute:(NSString *) kCTForegroundColorAttributeName value:(id)[[UIColor grayColor] CGColor] range:colorRange];
return mutableAttributedString; }];
return cell;
}
我将 TTT 属性标签添加到我的项目中。我想要 2 种不同的字体颜色来显示“喜欢”。但是我的项目不断崩溃。要格式化的示例字符串是:“andrew, john, amos like this photo。”
有什么建议吗?
【问题讨论】:
-
您能否更具体地说明控制台崩溃时会吐出的内容?如果你在断点的情况下运行,你可以在它崩溃后执行
bt来获得回溯吗?我的第一个想法是,您可能会遇到问题,通过将colorRange传递给-addAttribute:value:range而不检查是否找不到字符串 (colorRange.location == NSNotFound)
