Xcode 8 Official version has been released，I want the first time my project to the Swift 3 --After all, this is a trend。
During the migration process, I encountered a lot of problems--such as Xcode provides automated migration tool is not working，I've been waiting for more than two hours，after that I give up，I chose to manually migrate--after all,，Xcode's auto-correction is also very good。

Most of the time，We all want the button design style more in line with iOS，This will make the application interface does not look so jump，Even if the design does not look good，Nor was incompatible with the system。
"I'm not a designer，I don't know how to design beautiful style-but as close as possible to the system is not a wrong choice。 ” —— by Router
So it is for UIButton，Rounded corners + shadow should be the norm。
Obviously，This is the cheapest way - in fact the most expensive。It requires you to do a series of rounded picture for each button，[……]

Until we are，For example, third-party input method Sogou input method has a classic gesture - paddling around on the keyboard to move the cursor。And this feature I am also very common，所以，I want to implement it yourself。
The first thing I think of is UISwipeGestureRecognizer ，However, with predictable results，Paddling can only move the cursor one space，This is not what I want。
It seems the only way is to use UIPanGestureRecognizer[……]

At the beginning of a，Swift did not provide regular expression support，So we can only package，For example write a structure，Like this：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
struct MyRegex { let regex: NSRegularExpression? init(_ pattern: String) { regex = try? NSRegularExpression(pattern: pattern, options: .CaseInsensitive) } func match(input: String) -> Bool { if let matches = regex?.matchesInString(input, options: [], range: NSMakeRange(0, (input as NSString).length)) { return matches.count > 0 } else { return false } } } |
In fact, Swift already has support for regular expressions，We just need to：
|
1 |
let result = name.rangeOfString("^[a-z]", options: .RegularExpressionSearch) |
Direct will be able to get the captured content。
Gets to be a[crayon[……]
in most cases，If we want to get the contents of a section of the array (for example, front-to-middle，Some of the values of the array or the last)，This time you need to traverse the array to assign a new array：
|
1 2 3 4 5 6 7 |
let fixedArray = [1,2,3,4,5,6] var myArray:[Int] = [] for (i,n) in fixedArray.enumerate() { if i > 3 {break} myArray.append(n) } |
Such an array of short, better said it does not matter，However, if the array is relatively large and we need to value and more，It is clear that it is a waste of time to traverse up。
Swift in itself provides an array of features split，This mechanism is called [crayon-676afb[……]
When using python，Often you need to download some third-party framework，Fortunately, python has a similar apt package management tool，pip。
but，Although management packs can pip，But no source switching mirror，And we downloaded package，Most of the large foreign code hosting server，This often leads to a few hundred KB of package to download one hour。
Here we assume that，As a programmer you，Have been deployed to the computer HTTPS and HTTP proxy，We also said before[……]
