iOS presentViewController launches half-screen transparent UIViewController
No nonsense, just go to the code
1. How to open the parent page
/**
* page open configuration
*
* @param sender <#sender description#>
*/
- (IBAction)shwoViewAction:(id)sender {
TTViewController *tView = [[TTViewController alloc] init];
//Set the mode display style
[tView setModalPresentationStyle:UIModalPresentationOverCurrentContext];
// Required configuration
self.modalPresentationStyle = UIModalPresentationCurrentContext;
self.providesPresentationContextTransitionStyle = YES;
self.definesPresentationContext = YES;
[self presentViewController:tView animated:YES completion:nil];
}
2. Subpage rewrite viewWillLayoutSubviews, set position width and height
#define DeviceHeight [[UIScreen mainScreen] bounds].size.height
#define DeviceWidth [[UIScreen mainScreen] bounds].size.width
/**
* Set the position width and height
*/
- (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];
}
Finish work.
