我正在尝试使用CGAffineTransformMakeTranslate
模拟滑入和滑出来实现侧边栏效果。我想将我的侧边栏设置为滚动视图,以便添加更多数据,但根本无法滚动。
这是我的代码:
SidebarView
是一个UITableView
#import "SidebarView.h"
@interface SidebarView ()
@property (nonatomic, readwrite) CGFloat offsetX;
@end
@implementation SidebarView
#pragma mark - Initilization
- (void)setup {
// do initilization here
self.offsetX = self.frame.size.width;
[self registerClass:[UITableViewCell class] forCellReuseIdentifier:@"sidebarCell"];
}
- (void)awakeFromNib {
[self setup];
}
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
[self setup];
return self;
}
#pragma mark - Custom function
- (void)show {
self.transform = CGAffineTransformMakeTranslation(-self.offsetX, 0);
}
- (void)hide {
self.transform = CGAffineTransformMakeTranslation(-self.offsetX, 0);
}
我的视图控制器:
#import "ViewController.h"
#import "SidebarView.h"
@interface ViewController () <UITableViewDataSource>
@property (nonatomic) BOOL isMenuHide;
@property (nonatomic, strong) SidebarView *sidebarView;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.isMenuHide = YES;
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
if (self.sidebarView) {
self.sidebarView = nil;
}
if (self.view) {
self.view = nil;
}
}
- (SidebarView *)sidebarView {
if (!_sidebarView) {
CGRect frame = [[UIScreen mainScreen] bounds];
frame.size.width /= 2;
_sidebarView = [[SidebarView alloc] initWithFrame:frame];
_sidebarView.transform = CGAffineTransformMakeTranslation(-_sidebarView.offsetX, 0);
_sidebarView.contentSize = CGSizeMake(320, 960);
_sidebarView.scrollEnabled = YES;
_sidebarView.showsVerticalScrollIndicator = YES;
_sidebarView.dataSource = self;
}
return _sidebarView;
}
#define ANIMATE_DURATION 0.5
- (IBAction)showMenu:(UIBarButtonItem *)sender {
if (self.isMenuHide) {
[self.view addSubview:self.sidebarView];
[UIView animateWithDuration:ANIMATE_DURATION animations:^{
[self.sidebarView show];
self.view.transform = CGAffineTransformMakeTranslation(self.sidebarView.offsetX, 0);
}];
} else {
[UIView animateWithDuration:ANIMATE_DURATION animations:^{
[self.sidebarView hide];
self.view.transform = CGAffineTransformMakeTranslation(0, 0);
} completion:^(BOOL finished) {
[self.sidebarView removeFromSuperview];
}];
}
self.isMenuHide = !self.isMenuHide;
}
#pragma mark - UITableView Datasource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 11;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"sidebarCell"];
cell.textLabel.text = @"Bingo";
return cell;
}
@end
请告诉我“为什么我的滚动视图无法滚动”谢谢。
