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;
}
プロパティ名を指定してソート
function g_sortOn(_propertyName){
return function(a,b){
if( a[_propertyName] > b[_propertyName] )return 1;
if( a[_propertyName] < b[_propertyName] )return -1;
return 0;
}
}
var tmp = targetArray.sort( g_sortOn('name') );
使用言語を調べる
NSString*lang=[self getCurrentLanguage];
-(NSString*)getCurrentLanguage
{
NSArray *languages = [NSLocale preferredLanguages];
return [languages objectAtIndex:0];
}
ビット演算#1
type(INTEGER)を4ビット右シフトして右端が1であるレコードのidとtypeを取得する。
SELECT id,type FROM target_table_name WHERE type >> 4 & 1 = 1;
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;
}
URLを取得
$url = (empty($_SERVER["HTTPS"]) ? "http://" : "https://") . $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]
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;
}];
$.ajaxでcookieも送信
IE10未満は不可
$.ajax({
type:'post',
url:'url',
dataType:'text',
data:data,
crossDomain:true,
cache:false,
xhrFields: {
withCredentials:true
},
success:function(data, dataType){
},
error:function(XMLHttpRequest, textStatus, errorThrown){
},
complete:function(){
}
});
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
