ios - UIView subview clips during UIView transition animation -


i have created uiview subclass contains uiimageview subview. uiimageview subview may typically lie outside bounds of superview (my uiview subclass). not problem, no clipping occurs subview not 'clipstobounds'. until subview performs transition animation.

[uiview transitionwithview:self                       duration:0.7                        options:uiviewanimationoptiontransitionflipfromleft | uiviewanimationoptionallowanimatedcontent                     animations:^{                         self.bodyview.transform = cgaffinetransformmakescale(-1.0, 1.0);                     }                     completion:^(bool fin){                     }];

in example 'bodyview' uiimageview subview of uiview subclass. during transition bodyview clips. have tried setting 'maskstobounds' property of superview's layer 'no' has not solved problem.

my workaround @ present superview larger subview , not allow subview's frame exist outside superview's bounds not practical in application.

try imgview.contentmode=uiviewcontentmodescaleaspectfit;

c++ - What is the reason for not being able to deduce array size from initializer-string in member variable? -

consider code: struct foo { const char str[] = "test"; }; int main() { foo foo; } it fails compile both g++ , clang++, spitting out essentially error: array bound cannot deduced in-class initializer i understand standard says, there particular reason why? since have string literal seems compiler should able deduce size without problem, case when declare out-of-class const c-like null terminated string. the reason have possibility override in class initializer list in constructor. guess in end confusing. struct foo { foo() {} // str = "test\0"; // implementing easier if can see how big `str` is, foo() : str({'a','b', 'c', 'd'}) {} // str = "abcd0" const char str[] = "test"; }; notice replacing const char static constexpr works perfectly, , want anyway
