저는 iOS 개발에 상당히 익숙하며 앱 개발에 열심히 노력하고 있습니다. 멀티 뷰 앱에서 스 와이프 제스처를 사용할 수 없습니다. 코드를 붙여 넣고 있습니다. 오류를 지적하십시오. 보기 기반 응용 프로그램입니다. Multiview App에서 스 와이프 제스처
여기#import <UIKit/UIKit.h>
@interface mainViewController : UIViewController <UITableViewDelegate,UITableViewDataSource>
{
NSArray *listData;
}
@property (nonatomic, retain) NSArray *listData;
@end
mainViewController.h
지금 mainViewController.m#import "mainViewController.h"
@implementation mainViewController
@synthesize listData;
- (void)viewDidLoad {
NSArray *array =[[NSArray alloc] initWithObjects:@"Apple",@"Boy",@"Cat", nil];
self.listData = array;
[array release];
[super viewDidLoad];
}
- (void)dealloc
{
[listData release];
[super dealloc];
}
#pragma mark - View lifecycle
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.listData count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
SimpleTableIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [listData objectAtIndex:row];
//cell.textLabel.font = [UIFont boldSystemFontOfSize:50];
return cell;
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger row = [indexPath row];
NSString *rowValue = [listData objectAtIndex:row];
if([rowValue isEqualToString:@"Apple"])
{
cell.backgroundColor = [UIColor redColor];
}
else
if([rowValue isEqualToString:@"Boy"])
cell.backgroundColor= [UIColor yellowColor];
}
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSUInteger row = [indexPath row];
NSString *rowValue = [listData objectAtIndex:row];
if([rowValue isEqualToString:@"Apple"])
{
mainViewController* flashView=[[mainViewController alloc] initWithNibName:@"fl" bundle:[NSBundle mainBundle]];
[self.view addSubview:flashView.view];
}
//[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (void)viewDidUnload
{
[super viewDidUnload];
self.listData=nil;
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (CGFloat)tableView:(UITableView *)tableView
heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 110;
}
@end
나는 "FL"라는 XIB 파일이있는 UIViewSubController 클래스를 추가했습니다.
fl.h에서:
#define kMinimumLength 5
#define kMaxVariance 1
#import <UIKit/UIKit.h>
#import "mainViewController.h"
@protocol flDelegate;
@interface fl : UIViewController <UIGestureRecognizerDelegate>
{
CGPoint gestureStartPoint;
id <flDelegate> delegate;
}
@property CGPoint gestureStartPoint;
@property (nonatomic,retain) id <flDelegate> delegate;
@end
@protocol flDelegate
-(IBAction)flDidFinish:(fl *)controller;
@end
그리고 지금 fl.m에서 :
#import "fl.h"
@implementation fl
@synthesize delegate;
@synthesize gestureStartPoint;
- (void)dealloc
{
[super dealloc];
}
#pragma mark - View lifecycle
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch =[touches anyObject];
gestureStartPoint =[touch locationInView:self.view];
}
-(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch =[touches anyObject];
CGPoint CurrentPosition =[touch locationInView:self.view];
if(CurrentPosition.x >= kMinimumLength)
{
NSLog(@"Go");
}
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
여기에 모든 노력하지만, 와이프를 감지되지 않으며, 이동을 인쇄 할 수 없습니다.
코드를 undersatnd 수 있지만 내 코드에서 오류를 찾을 수 없습니다, 위의 코드를 확인하고 오류를 가리 킵니다. –
