iphone - Resize a UIView -

i have 2 uiviews, containerview , testview. width of testview bigger of containerview. in such case, when add testview subview containerview, there comes problem. frames of testview goes beyond bounds of containerview. here code -

- (void)viewdidload {     [super viewdidload];     // additional setup after loading view, typically nib.      uiview *containerview = [[uiview alloc] initwithframe:cgrectmake(60, 154, 200, 200)];     containerview.backgroundcolor = [uicolor graycolor];     containerview.clipstobounds = no;      uiview *testview = [[uiview alloc] initwithframe:cgrectmake(0, 0, 260, 100)];     testview.backgroundcolor = [uicolor yellowcolor];     testview.layer.borderwidth = 3;     testview.layer.bordercolor = [[uicolor blackcolor] cgcolor];     testview.center = cgpointmake(containerview.frame.size.width / 2, containerview.frame.size.height / 2);      uilabel *label = [[uilabel alloc] initwithframe:cgrectmake(15, 25, 230, 50)];     label.text = @"this label test size";      [testview addsubview:label];     [containerview addsubview:testview];     [self.view addsubview:containerview]; } 

output code -

when containerview.clipstobounds = yes;, output -

but need - (edited image)

when add testview width/height bigger superview- containerview, frame of testview(including children) should adjusted that, fits inside superview.

i welcome ideas..!

the modern way create view, add constraints view establish relationship containing view , add view subview.

that way aren't messing frames, , resizing rotation handled you.

here example code similar asking for

- (void)viewdidload {     [super viewdidload];      // create containing view     uiview *greyview = [[uiview alloc] initwithframe:cgrectzero];     greyview.backgroundcolor = [uicolor graycolor];     greyview.translatesautoresizingmaskintoconstraints = no;      [self.view addsubview:greyview];      // create label go containing view     uilabel *label = [[uilabel alloc] initwithframe:cgrectzero];     label.translatesautoresizingmaskintoconstraints = no;     label.text = @"example text";      label.backgroundcolor = [uicolor yellowcolor];      [greyview addsubview:label];      nsdictionary *bindings = nsdictionaryofvariablebindings(greyview, label);      // set constraints greyview relative it's superview - cover     [self.view addconstraints:[nslayoutconstraint constraintswithvisualformat:@"h:|[greyview]|" options:nslayoutformatdirectionleadingtotrailing metrics:nil views:bindings]];     [self.view addconstraints:[nslayoutconstraint constraintswithvisualformat:@"v:|[greyview]|" options:nslayoutformatdirectionleadingtotrailing metrics:nil views:bindings]];      // set constraints label pinned equally padding     [greyview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"h:|-(30)-[label]-(30)-|" options:nslayoutformatdirectionleadingtotrailing metrics:nil views:bindings]];     [greyview addconstraints:[nslayoutconstraint constraintswithvisualformat:@"v:|-(30)-[label]-(30)-|" options:nslayoutformatdirectionleadingtotrailing metrics:nil views:bindings]];  } 

if want see in action , tweak constraints yourself, i've uploaded simple example project can use.
