UILabel *label = [UILabel alloc]init]; label.clipsToBounds = true; label.layer.cornerRadius = 3.0f; UIView *view = [UIView alloc]init]; view.clipsToBounds = true; view.layer.cornerRadius = 3.0f;UIButtonの場合
UIButton *button = [UIButton alloc]init]; button.layer.cornerRadius = 3.0f;
UIFont *barButtonTitleFont = [UIFont fontWithName:@"mplus-2p-light" size:13];
UIColor *barButtonTitleColor = [UIColor whiteColor];
[[UIBarButtonItem appearance] setTitleTextAttributes:@{UITextAttributeFont:barButtonTitleFont, UITextAttributeTextColor:barButtonTitleColor} forState:UIControlStateNormal];
を記述。これで、BackButtonのフォントが変わる UILabel* label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 44)];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont fontWithName:@"mplus-2p-light" size:22.0f];
label.textColor = [UIColor flatWhiteColor];
label.text = @"タイトル";
label.textAlignment = NSTextAlignmentCenter;
self.navigationItem.titleView = label;
を記述。これで、タイトルのフォントが変わる。
[NSThread sleepForTimeInterval:1.0]; [UIApplication sharedApplication].statusBarHidden = NO;を記述する。
@interface sampleClass:NSObject
{
NSString *_string; //インスタンス変数の定義
double _number; //インスタンス変数の定義
}
@property (nonatomic) NSString* string; //プロパティを記述すると、getterとsetterが自動で生成される
@end
sampleClass.m
@implementation sampleClass
@synthesize string = _string; //インスタンス変数とプロパティを明示的に紐付ける
//プロパティを記述していない場合、自分でgetterとsetterを作る
- (double)number{
return _number;
}
- (void)setNumber:(double)number{
_number = number;
}
@end
setter/getterを自分で作る場合の利点は、setter/getter内に好きなことを記述できる- (void)prepareShowRightPanel;を追記
- (void)_showRightPanel:(BOOL)animated bounce:(BOOL)shouldBounce {
self.state = JASidePanelRightVisible;
[self _loadRightPanel];
[self _adjustCenterFrame];
if (animated) {
[self _animateCenterPanel:shouldBounce completion:nil];
} else {
self.centerPanelContainer.frame = _centerPanelRestingFrame;
[self styleContainer:self.centerPanelContainer animate:NO duration:0.0f];
if (self.style == JASidePanelMultipleActive || self.pushesSidePanels) {
[self _layoutSideContainers:NO duration:0.0f];
}
}
if (self.style == JASidePanelSingleActive) {
self.tapView = [[UIView alloc] init];
}
[self prepareShowRightPanel];//これを追加
[self _toggleScrollsToTopForCenter:NO left:NO right:YES];
}
次に、JASidePanelControllerのサブクラスに
- (void)prepareShowRightPanel {
NSLog(@"show right panel");
}
を記述dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0),^{
[self doSomething]; //別スレッド
dispatch_sync(dispatch_get_main_queue(), ^{
[self doSomething]; // メインスレッド
});
});
この場合、別スレッドに重い処理を書いて、メインスレッドはUIの描画が一般的らしい
PRIORITYで優先度も設定できるそして、インスタンスメソッドはスレッドを指定して実行することができる[self performSelectorOnMainThread:@selector(refresh)
withObject:nil
waitUntilDone:NO];
NSOperationQueue *queue = [NSOperationQueue new];
MyOperation *operation = [MyOperation new];//NSOperationを継承したクラスを作成
[queue addOperation:operation];
NSInvocationOperation *invOperation = [[NSInvocationOperation alloc]initWithTarget:self selector:@selector(aaa) object:nil]; [queue addOperation:invOperation];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
// ここに非同期でバックグラウンドに投げたい処理を書く
});
#importmyCell.m@interface myCell : UICollectionViewCell @property (strong, nonatomic) IBOutlet UILabel *cellLabel; @end
#import "myCell.h"
@implementation myCell
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
-(void)awakeFromNib
{
NSLog(@"bundleLoader waked");
}
@end
5. あとはcollectionViewController.mで
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView
cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
NSString *identifier = @"myCell";
static BOOL nibCellLoaded = NO;
if(!nibCellLoaded){
UINib *nib = [UINib nibWithNibName:@"myCell" bundle:nil];
[collectionView registerNib:nib forCellWithReuseIdentifier:identifier];
nibCellLoaded = YES;
}
myCell *cell = (OBWeather*)[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
cell.backgroundColor = [UIColor greenColor];
return cell;
}
最後に思ったけど、
クラス名とidentifierって一緒じゃない方がいいのかなあ
