iphone : sizeWithFont method does not identify the '\n' from string

由 孤人 提交于 2019-12-07 05:41:43

Can't scroll in UIScrollView as soon as UILabel / other subview added in Storyboard

由 痴心易碎 提交于 2019-12-07 03:30:37
问题 I encountered the following problem: as soon as I add e.g. a UILabel to my UIScrollView - using the storyboard - the scroll view stops "working" (with that I mean you cannot scroll at all). However adding a subview programmatically the scroll view works fine but since I prefer designing my apps visually with storyboard I would like to solve this mysterious error. Does anyone knows why this error is occurring? Thanks in advance :) PS: I do set the contentSize of my scrollView, so this cannot

How can I remove UILabel's gray border on the right side?

由 那年仲夏 提交于 2019-12-06 17:11:55
问题 I have added an UILabel to a custom cell's contentView. I met with a strange side effect. On the right border there is a gray edge. I don't know why. I just added an ordinary UILabel, I have done nothing else. UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero]; label.text = @"value1"; label.textAlignment = UITextAlignmentCenter; [self.contentView addSubview:label]; - (void)layoutSubviews { UILabel *label = [self.contentView.subviews objectAtIndex:i]; label.frame = CGRectMake(…); }

Objective-C: How to animate “Loading…” text on a UILabel

问题 In my app I need to display a "Loading" text in an UILabel, repeatedly as follows: Loading Loading. Loading.. Loading... Loading Loading. Loading.. Loading... How can I do it? Any suggestion, please? 回答1: You could easily implement such a behavior yourself – see my example below. But like trojanfoe suggested, I would rather use a nice library like MBProgressHUD or MarqueeLabel - (void) updateLoadingLabel; { if(self.loading) { if([self.labelLoading.text isEqualToString:@"Loading…"]) { self

I read this and this but they don't seem to address the issue. And the answers to this seem to go off a tangent in NSCoding and friends, so ... Consider: - (NSAttributedString *) attributedStringForText: (NSString *) text { NSMutableAttributedString* attrStr = [[NSMutableAttributedString alloc] initWithString:text]; UIFont * bigF = [UIFont fontWithName:@"OpenSans-Extrabold" size:20.0f] ; UIFont * smaF = [UIFont fontWithName:@"OpenSans-Extrabold" size:12.0f] ; [attrStr addAttribute:NSFontAttributeName value:bigF range:(NSRange){0, 3}] ; [attrStr addAttribute:NSFontAttributeName value:smaF range
