问题 So I am able to set up dynamic height sizing with auto layout when I have only one label that changes the height based on the length of the string. My problem is that if I add another UILabel that should do the same, things don't work out. I am setting both the Content Hugging priority and the Compression Resistance to 1000 for both == I get warnings of ambiguity If I set the Content Hugging (Vertical) for the second UILabel to 999 or 250 then it works great but only if the second label has 2

问题 I am successfully adding links to a UILabel via OHAttributeLabel and -(void)addCustomLink:(NSURL*)linkUrl inRange:(NSRange)range; In other words, the correct range is underlined and looks like a link. However, I cannot click/touch on the link. Is there anything else that must be done that the addCustomLink method on the range of text?

问题 I've seen answers to vertical resizing that involve autolayout, but the UILabel s I'm creating are only needed at runtime. (I might need anywhere from zero to many of these labels.) Examples (ignore the color) Short text (note same width as longer text): Longer text (note same width as shorter text example with more lines for add'l text): If the text can fit in one line of fixed width, the label shouldn't need to resize vertically. But if there are more characters, the label should keep

问题 I have a little iOS5 app that shows images. I click on the image to show its information. I'd like the information to fade away after a few seconds. Is there a good method to do this?

问题 I get the following errors when I attempt to set a label's Preferred Width to Automatic in a storyboard: Attribute Unavailable: Automatic Preferred Max Layout Width is not available on iOS versions prior to 8.0 Since I need my layout to work on both iOS 7 and 8, I was planning to do the following: Set the value to Explicit in the storyboard.
