Hi All,
Im developing native iOS application using sup 2.1.3 . Im getting error While retrieving image from SUP database. Here i'm trying to get image from database and show in imageView.can any one help me how to fix this issue?
In database image datatype is 'LONG Binary' .
My table Schema:
CREATE TABLE dba.ImagesTable (
RowID INT NOT NULL,
ImageName VARCHAR(20) NOT NULL,
PhotoData LONG BINARY NOT NULL,
)
IN SYSTEM
;
ALTER TABLE dba.ImagesTable
ADD CONSTRAINT ASA137 PRIMARY KEY CLUSTERED (RowID)
;
ALTER TABLE dba.ImagesTable
ADD CONSTRAINT ASA138 UNIQUE NONCLUSTERED (RowID)
;
in Xcode:
[SUP107SUP107DBsynchronize];
SUP107ImagesTable *imgTable =[[SUP107ImagesTablealloc]init];
SUP107ImagesTableList *list =[SUP107ImagesTablefindAll];
SUP107ImagesTable * oneRecord =[list objectAtIndex:0];
NSLog(@"rowId:%d---imageName:%@---photoData:%@---photoLenght:%d",oneRecord.rowID,oneRecord.imageName,oneRecord.photoData,oneRecord.photoDataLength);
NSData *tempData =[[NSDataalloc]init];
SUPBigBinary *responseBinaryData = (SUPBigBinary *)oneRecord.photoData.value;
@try {
[responseBinaryData openForWrite:[oneRecord.photoDatalength]];
[responseBinaryData write:tempData];
}
@catch (NSException *exception) {
NSLog(@"exception: %@",[exception description]);
}
UIImageView *imgView =[[UIImageViewalloc] initWithFrame:CGRectMake(50,50,100,100)];
[self.windowaddSubview:imgView];
UIImage * tempImage =[UIImageimageWithData:tempData];
imgView.image = tempImage;
[responseBinaryData close];
Error Log:
