Mango is a DSL which syntax is very similar to Objective-C，Mango is also an iOS App hotfix SDK. You can use Mango method replace any Objective-C method.

equivalent to Objective-C `void`.
equivalent to Objective-C `BOOL`.
equivalent to Objective-C `unsigned char`、`unsigned short`、`unsigned int`、`unsigned long`、`unsigned long long`、`NSUInteger`.
equivalent to Objective-C `char`、`short`、`int`、`long`、`long long`、`NSInteger`.
