调用NSArray的类方法

Question

我有这段代码，我想调用该类方法来获取imageView的一些参数，但是我不知道如何调用它，您能帮我吗？

+ (NSArray*)getRGBAsFromImage:(UIImage*)image atX:(int)xx andY:(int)yy count:(int)count

Answer 1

You can call that method using your class name.

If your class is like:

@interface myClass

+ (NSArray*)getRGBAsFromImage:(UIImage*)image atX:(int)xx andY:(int)yy count:(int)count

@end

you can call this method like:

NSArray *temp = [myClass getRGBAsFromImage:yourImage atX:x andY:y count:count];

Answer 2

To call it you just use the class name...

If this is on UIImage then...

[UIImage getRGBAsFromImage:someImage atX:xVal andY:yVal count:countVal];
