- Download the files UIView+ExtraAttributes.h and UIView+ExtraAttributes.m.
- Add them to your Xcode project.
- Include UIView+ExtraAttributes.h in your implementation file when you want to use the attributes.
4 UIViews are placed at the corners of the blue UIView. The blue UIView's attributes are displayed.
Here's the code:
UIView *view0 = [[UIView alloc] initWithFrame:CGRectMake(self.view.leftSideX + 200, self.view.topSideY + 200, self.view.width/4, self.view.height/4)];
NSLog(@"view0 frame: (%f, %f, %f, %f)", view0.frame.origin.x, view0.frame.origin.y, view0.frame.size.width, view0.frame.size.height);
view0.backgroundColor = [UIColor blueColor];
[self.view addSubview:view0];
//translucent view originating at view0's top left corner
UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake(view0.topLeftCorner.x, view0.topLeftCorner.y, 100, 100)];
view1.backgroundColor = [[UIColor redColor] colorWithAlphaComponent:0.5];
[self.view addSubview:view1];
//translucent view originating at view0's top right corner
UIView *view2 = [[UIView alloc] initWithFrame:CGRectMake(view0.topRightCorner.x, view0.topRightCorner.y, 50, 50)];
view2.backgroundColor = [[UIColor purpleColor] colorWithAlphaComponent:0.5];
[self.view addSubview:view2];
//translucent view originating at view0's bottom left corner
UIView *view3 = [[UIView alloc] initWithFrame:CGRectMake(view0.bottomLeftCorner.x, view0.bottomLeftCorner.y, 75, 75)];
view3.backgroundColor = [[UIColor yellowColor] colorWithAlphaComponent:0.5];
[self.view addSubview:view3];
//translucent view originating at view0's bottom right corner
UIView *view4 = [[UIView alloc] initWithFrame:CGRectMake(view0.bottomRightCorner.x, view0.bottomRightCorner.y, 25, 25)];
view4.backgroundColor = [[UIColor greenColor] colorWithAlphaComponent:0.5];
[self.view addSubview:view4];
//display a textView with the attributes of view0
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(view4.bottomRightCorner.x, view4.bottomRightCorner.y, 200, 500)];
NSString *topLeftCornerString = [NSString stringWithFormat:@"topLeftCorner: (%f, %f)", view0.topLeftCorner.x, view0.topLeftCorner.y];
NSString *topRightCornerString = [NSString stringWithFormat:@"topRightCorner: (%f, %f)", view0.topRightCorner.x, view0.topRightCorner.y];
NSString *bottomRightCornerString = [NSString stringWithFormat:@"bottomRightCorner: (%f, %f)", view0.bottomRightCorner.x, view0.bottomRightCorner.y];
NSString *bottomLeftCornerString = [NSString stringWithFormat:@"bottomLeftCorner: (%f, %f)", view0.bottomLeftCorner.x, view0.bottomLeftCorner.y];
NSString *topSideYString = [NSString stringWithFormat:@"topSideY: %f", view0.topSideY];
NSString *rightSideXString = [NSString stringWithFormat:@"rightSideX: %f", view0.rightSideX];
NSString *bottomSideYString = [NSString stringWithFormat:@"bottomSideY: %f", view0.bottomSideY];
NSString *leftSidexString = [NSString stringWithFormat:@"leftSideX: %f", view0.leftSideX];
NSString *widthString = [NSString stringWithFormat:@"width: %f", view0.width];
NSString *heightString = [NSString stringWithFormat:@"height: %f", view0.height];
textView.text = [NSString stringWithFormat:@"Blue View Attributes:\n%@\n%@\n%@\n%@\n%@\n%@\n%@\n%@\n%@\n%@",
topLeftCornerString, topRightCornerString, bottomRightCornerString, bottomLeftCornerString,
topSideYString, rightSideXString, bottomSideYString, leftSidexString,
widthString, heightString];
textView.scrollEnabled = NO;
