获取ios屏幕大小（去掉状态条）
- (CGSize) screenSize{ UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; CGSize size = [UIScreen mainScreen].bounds.size; UIApplication *application = [UIApplication sharedApplication]; if (UIInterfaceOrientationIsLandscape(orientation)) { size = CGSizeMake(size.height, size.width); } if (application.statusBarHidden == NO) { size.height -= MIN(application.statusBarFrame.size.width, application.statusBarFrame.size.height); } return size;}
