IOS开发之UIView总结1

太长了，请看 http://blog.csdn.net/xdrt81y/article/details/9128695

1. performSelector:


2. performSelector:withObject:


3. performSelector:withObject:withObject:

实际调用

1. [self performSelector:@selector(displayViews) withObject:nil afterDelay:1.0f];

有三个方法分别是

1. //父视图


2. [self.view superview]


3. //所有子视图


4. [self.view subviews]


5. //自身的window


6. self.view.window

循环一个视图下面所有视图的方法

1. NSArray *allSubviews(UIView *aView)


2. {


3. NSArray *results = [aView subviews];


4. for (UIView *eachView in [aView subviews])


5. {


6. NSArray *riz = allSubviews(eachView);


7. if (riz) {


8. results = [results arrayByAddingObjectsFromArray:riz];


9. }


10. }


11. return results;


12. }

循环返回一个APPLICATION里面所有的VIEW

1. // Return all views throughout the application


2. NSArray *allApplicationViews()


3. {


4. NSArray *results = [[UIApplication sharedApplication] windows];


5. for (UIWindow *window in [[UIApplication sharedApplication] windows])


6. {


7. NSArray *riz = allSubviews(window);


8. if (riz) results = [results arrayByAddingObjectsFromArray: riz];


9. }


10. return results;


11. }

找出所有的父视图

1. // Return an array of parent views from the window down to the view


2. NSArray *pathToView(UIView *aView)


3. {


4. NSMutableArray *array = [NSMutableArray arrayWithObject:aView];


5. UIView *view = aView;


6. UIWindow *window = aView.window;


7. while (view != window)


8. {


9. view = [view superview];


10. [array insertObject:view atIndex:0];


11. }


12. return array;


13. }
