iOS presentViewController 推出半屏幕透明 UIViewController
不废话，直接上代码
1.父页面打开方式
/**
* 页面打开配置
*
* @param sender <#sender description#>
*/
- (IBAction)shwoViewAction:(id)sender {
TTViewController *tView = [[TTViewController alloc] init];
//设置模式展示风格
[tView setModalPresentationStyle:UIModalPresentationOverCurrentContext];
//必要配置
self.modalPresentationStyle = UIModalPresentationCurrentContext;
self.providesPresentationContextTransitionStyle = YES;
self.definesPresentationContext = YES;
[self presentViewController:tView animated:YES completion:nil];
}
2.子页面重写viewWillLayoutSubviews，设置位置宽高
#define DeviceHeight [[UIScreen mainScreen] bounds].size.height
#define DeviceWidth [[UIScreen mainScreen] bounds].size.width
/**
* 设置位置宽高
*/
- (void)viewWillLayoutSubviews {
self.view.frame = CGRectMake(self.view.frame.origin.x, DeviceHeight / 2, DeviceWidth, DeviceHeight / 2);
//self.view.backgroundColor = [UIColor clearColor];
//self.view.backgroundColor = [UIColor colorWithRed:1 green:0 blue:0 alpha:0.868f];
}
打完收工。
