DynamicOC
A hotfix library based on flex/yacc. You can call any Objective-C class and method using DynamicOC. DynamicOC is functionally similar to JSPath, but it only needs to write native OC syntax to implement hotfix.
Features
- dynamically execute Objective-C code
- dynamically execute C function and block
- dynamically add property
- dynamically replace method
- dynamically add method
- Completed and detailed unit test
- powerful OC syntax parser based on flex/yacc
- support CGRect/CGSize/CGPoint/NSRange/UIEdgeInsets/CGAffineTransform C-struct ...
Basic Usage
dynamically execute block
NSString* text = @" \
__block int result = 0;\
UIView* view = [[UIView alloc]init];\
void(^blk)(int value) = ^(int value){\
view.tag = value;\
};\
blk(1024);\
return view.tag;";
ASTNode* root = [ASTUtil parseString:text];
ASTVariable* result = [root execute];
NSAssert([result.value doubleValue] == 1024, nil);
dynamically execute C function
int echo(int value) {
return value;
}
NSString* text = @" \
[OCCfuntionHelper defineCFunction:@\"echo\" types:@\"int, int\"]; \
return echo(1024);";
ASTNode* root = [ASTUtil parseString:text];
ASTVariable* result = [root execute];
NSAssert([result.value doubleValue] == 1024, nil);
dynamically add property
NSString* text = @" \
[OCCfuntionHelper defineCFunction:@\"objc_setAssociatedObject\" types:@\"void,id,void *,id,unsigned int\"];\
[OCCfuntionHelper defineCFunction:@\"objc_getAssociatedObject\" types:@\"id,id,void *\"];\
NSString* key = @\"key\"; \
objc_setAssociatedObject(self, key, @(1024), 1);\
return objc_getAssociatedObject(self, key);";
ASTNode* root = [ASTUtil parseString:text];
ASTVariable* result = [root execute];
NSAssert([result.value doubleValue] == 1024, nil);
Supported Syntax
- if/else while do/while for
- return break continue
- i++ i-- ++i --i
- +i -i !i
- + - * / % Arithmetic operation
- >> << & | ^ Bit operation
- && || >= <= != > < Compare operation
- ?:
- __block
- array[i] dict[@""]
- @666 @() @[] @{}
- self super
- self.property
- self->_property
- most of objective-c keyword
TODO
- @available()
- [NSString stringWithFormat:"%d",value] : use [NSString stringWithFormat:"%@",@(value)] instead。
- dispatch_async / dispatch_after ...
- *stop =YES, in block
- fix bugs
