UILabelを複製する

-(UILabel*)getCloneUILabelByUILabel:(UILabel*)label
{
    NSData *archivedData = [NSKeyedArchiver archivedDataWithRootObject:label];
    return [NSKeyedUnarchiver unarchiveObjectWithData:archivedData];
}
UILabel*cloneLabel = [self getCloneUILabelByUILabel:modelLabel];

ステータスバーのサイズを取得

-(CGSize)getStatusBarSize
{
    CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
    return statusBarFrame.size;
}

使用言語を調べる

NSString*lang=[self getCurrentLanguage];

-(NSString*)getCurrentLanguage
{
    NSArray *languages = [NSLocale preferredLanguages];
    return [languages objectAtIndex:0];
}

2つの日付の差を日数で出す

int dayCount = [self getDaysCountByTwoDateString:@"2014-04-01" endDateString:@"2014-04-04"];
-(int)getDaysCountByTwoDateString:(NSString*)startDateString endDateString:(NSString*)endDateString
{
    NSDateFormatter *inputDateFormatter = [[NSDateFormatter alloc] init];
    [inputDateFormatter setDateFormat:@"yyyy-MM-dd"];
    
    NSDate *startInputDate = [inputDateFormatter dateFromString:startDateString];
    NSDate *endInputDate = [inputDateFormatter dateFromString:endDateString];
    
    float tmp= [endInputDate timeIntervalSinceDate:startInputDate];
    int day=(int)( tmp / (3600.0*24.0) );
    return day;
}

animateWithDurationを途中で止める

アニメーション実行

[UIView animateWithDuration:10.0f animations:^{
    targetView.frame=CGRectMalke(0.0,0.0,100.0,100.0);
} completion:^(BOOL finished) {
    
}];

アニメーション中止

[UIView setAnimationBeginsFromCurrentState:YES];
[UIView animateWithDuration:0.001 animations:^{
    targetView.alpha = 1.0;
}];

数字の桁を合わせる

NSString*numStr1=[NSString stringWithFormat:@"%02d",i];//2桁
NSString*numStr2=[NSString stringWithFormat:@"%04d",i];//4桁 i=3のとき"0003"となる

pagingEnabled=YESのUIScrollViewのスクロール先のページインデックスを取得

ヘッダーファイル

<UIScrollViewDelegate>

メインファイル

-(void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset
{
    CGFloat width = scrollView.frame.size.width;
    NSInteger page = (targetContentOffset->x + (0.5f * width)) / width;
    int index=(int)page;   
}

文字列に指定の文字列が含まれているか判定

BOOL has = [self hasSpecifiedString:@"abcdefg" searchString:@"cde"];
-(BOOL)hasSpecifiedString:(NSString*)targetString searchString:(NSString*)searchString
{
    NSRange searchResult = [targetString rangeOfString:searchString];
    return !(searchResult.location==NSNotFound);
}

performSelectorの警告を消す

#define SuppressPerformSelectorLeakWarning(Stuff) \
do { \
_Pragma("clang diagnostic push") \
_Pragma("clang diagnostic ignored \"-Warc-performSelector-leaks\"") \
Stuff; \
_Pragma("clang diagnostic pop") \
} while (0)

if (_delegate && _selector && [_delegate respondsToSelector:_selector]) {
    SuppressPerformSelectorLeakWarning([_delegate performSelector:_selector withObject:[NSNumber numberWithBool:success]]);
}

フォルダを作る

-(BOOL)makeDir:(NSString*)dirPath
{
    NSString* path=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
    path=[path stringByAppendingPathComponent:dirPath];
    NSError *error;
    BOOL result = [[NSFileManager defaultManager] createDirectoryAtPath:path
                                            withIntermediateDirectories:YES
                                                             attributes:nil
                                                                  error:&error];
    return result;
}

[self makeDir:@"test1/test2/jack"];

上記を実行すると下記の3つのフォルダが作られる。
test1
test1/test2
test1/test2/jack
