虽然我理解为什么我会收到错误
'',原因:' - [UIPopoverController initWithContentViewController:]在未在UIUserInterfaceIdiomPad下运行时调用。'
纠正它变得有点棘手。我的弹出只需要在ipad而不是iphone版本上。我省略了iphone if statement
的任何代码,但仍然崩溃了。 。假设我必须在iphone上调用一个视图以及它的通用应用程序,我只需在if iphone statement
中调用nib,这也不起作用。
- (IBAction)popZs:(id)sender {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
} else {
[self->popoverController setPopoverContentSize: CGSizeMake(601, 571)];
[popoverController presentPopoverFromRect:((UIButton *)sender).bounds
inView:sender
permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
}
}
else {
/////using iPhone/////not sure how to handle this spart
zsTablePop *pop = [[zsTablePop alloc] init];
pop.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[pop presentModalViewController:pop animated:YES];
}
即使使用if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
创建pop over
.m
#import "ICCircuitDetails.h"
#import "zsTablePop.h" ///////////////pop over xib/////
@interface ICCircuitDetails ()
{
zsTablePop *controller;
UIPopoverController *popoverController;
}
///////more code/////////////
- (id)initWithCircuit:(Circuit *)circuit
{
self = [super initWithCertificate:circuit.distributionBoard.certificate];
if (self) {
self.circuit = circuit;
[[NSBundle mainBundle] loadNibNamed:@"ICCircuitDetails" owner:self options:nil];
self.view.contentSize = CGSizeMake(self.contentView.frame.size.width, self.contentView.frame.size.height);
///////////other code here/////////////////
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
controller = [[zsTablePop alloc] initWithNibName:@"zsTablePop" bundle:nil];
popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
答案 0 :(得分:1)
您的错误消息显示您尝试实例化弹出窗口。代码只是关于呈现它。您还需要处理实例化。
