Limiting Characters to a specfic width

阅读更多关于 Limiting Characters to a specfic width

问题 I have run into this problem a few times. I have no problem limiting characters in a string to a specific number. However, some characters are longer than others so it wraps to another line or makes my DIV element wider and not uniform with the rest of my website. For instance: Literacy - Is it the Sa Machu Picchu, Cuzco, Pe are the exactly the same amount of characters (23) including spaces but the Machu Pichu one is longer in terms of the actual width on screen. Is there any way to have a

阅读更多关于 How do you set the font size on a UIBarButtonItem?

I can't find a way to set the font size of the title in a custom UIBarButtonItem. The only way I can think of getting around this is to set it as an image which I would like to avoid. Any other suggestions? In a easy way, simply: Objective-C: NSUInteger fontSize = 20; UIFont *font = [UIFont boldSystemFontOfSize:fontSize]; NSDictionary *attributes = @{NSFontAttributeName: font}; UIBarButtonItem *item = [[UIBarButtonItem alloc] init]; [item setTitle:@"Some Text"]; [item setTitleTextAttributes:attributes forState:UIControlStateNormal]; self.navigationItem.rightBarButtonItem = item; Swift: let

I just upgraded to xcode 4.5 with iOS 6.0 and it's highlighting a warning on all the UILabels in my XIB files saying "minimum font size deprecated on ios version 6.0". Does anyone know what this is referring to and how to fix it?

ContentEditable - Get current font color/size

阅读更多关于 ContentEditable - Get current font color/size

I'm working on Rich Text Editor for web browser and I want to work with values of current font color and size in the RTE/ContentEditable element. Is there some preselected function to get these values, like execCommand, which is connected directly with ContentEditable element? Or should I use some text range jQuery library which will get these properties? You can use document.queryCommandValue() to get the colour and font size of the current selection in all major browsers: Live demo: http://jsfiddle.net/timdown/AJBsY/ Code: var colour = document.queryCommandValue("ForeColor"); var fontSize =

Shortcut for changing font size

Does anybody know if there is a shortcut or something similar for changing the font size in the text editor in Visual Studio 2008? What I mean is something like Ctrl + mouse wheel like in Firefox. Accessing the Options window and then selecting Environment > Fonts and Colors is fine if you don't have to change the font size all the time, but in my case, I would like to be able to change it depending on what I am doing (writing and reading code or just reading it). I guess I could create two almost identical settings files and import them whenever I want, but that is even slower. In the Macros
