extension：可以写在类外面 |
| - (float) check: (int) count { } |
func check: (count: Int) -> Float { } |
|
int n = 0
n ++
|
var n: Int = 0
n += 1
|
|
NSString *str = @"你好"
str = [NSString stringwithformat:@"%s%d", str, n];

var str: String = "你好"
str += String(n)

NSArray * ary = [NSArray array]
ary = @[
[NSValue valueWithCGPoint:CGPointMake(0.9, 0.1)],
[NSValue valueWithCGPoint:CGPointMake(9.8, 9.7)]
];
|
var ary = [NSValue]()
ary = [
NSValue(cgPoint: CGPoint(x: 0.1, y: 0.9)),
NSValue(cgPoint: CGPoint(x: 9.8, y: 9.7))
]
ary.append(NSValue(cgPoint: CGPoint(x: 0.1, y: 0.9)))

| NSDictionary *dic |
var dic = [Int: CGPoint]()
字典可以用Int类型做key
dic[n] = CGPoint(x:x, y:y)添加值
没有NSMutableDictionary和NSDictionary 区分
