我想运行我的基于视图的窗口应用程序与ticker.i有股票代码,但它是在可可..所以我怎么可以整合可可应用程序在我的项目。我怎样才能整合iPhone应用程序中的代码
这是TickerView.h文件
#import <Cocoa/Cocoa.h>
@interface TickerView : NSTextView {
@private
NSTimer *mTimer;
double mOffset;
}
- (NSString *)stringValue;
- (void)setStringValue:(NSString *)stringValue;
- (void)appendString:(NSString *)s;
- (IBAction)startAnimation:(id)sender;
- (IBAction)stopAnimation:(id)sender;
@end
这是TickerView.m文件
#import "TickerView.h"
@implementation TickerView
- (id)initWithFrame:(NSRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self setEditable:NO];
NSTextContainer *container = [self textContainer];
[container setWidthTracksTextView:NO];
[container setContainerSize:NSMakeSize(99999., frame.size.height)];
}
return self;
}
- (void)dealloc {
[self stopAnimation:self];
[super dealloc];
}
- (void)drawRect:(NSRect)rect {
[super drawRect:rect];
}
- (NSString *)stringValue {
return [[self textStorage] string];
}
- (NSDictionary *)standardAttributes {
return [NSDictionary dictionaryWithObjectsAndKeys:
[NSFont fontWithName:@"Helvetica" size:([self frame].size.height * 0.8)], NSFontAttributeName,
[NSColor redColor], NSForegroundColorAttributeName,
nil];
}
- (void)setStringValue:(NSString *)s {
NSRange fullRange = NSMakeRange(0, [[self textStorage] length]);
NSAttributedString *sa = [[[NSAttributedString alloc]initWithString:s attributes:[self standardAttributes]] autorelease];
[[self textStorage] replaceCharactersInRange:fullRange withAttributedString:sa];
}
- (void)appendString:(NSString *)s {
NSRange endRange = NSMakeRange([[self textStorage] length], 0);
NSAttributedString *sa = [[[NSAttributedString alloc]initWithString:s attributes:[self standardAttributes]] autorelease];
[[self textStorage] replaceCharactersInRange:endRange withAttributedString:sa];
}
- (IBAction)startAnimation:(id)sender {
if (nil == mTimer) {
mTimer = [NSTimer scheduledTimerWithTimeInterval:1./60. target:self selector:@selector(step:) userInfo:nil repeats:YES];
}
}
- (IBAction)stopAnimation:(id)sender {
if (mTimer) {
[mTimer invalidate];
[mTimer release];
mTimer = nil;
}
}
- (void)step:(NSTimer *)timer {
mOffset -= 2; // pixels per tick
[self setTextContainerInset:NSMakeSize(mOffset, 0)];
[self setNeedsDisplay:YES];
}
@end
感谢您的suggetion .. 但它仍然无法正常工作。 – Pradeep 2010-07-08 14:07:28
需要更多的信息,而不是'不工作';) - 如果你编辑你的问题,你可以添加更多的细节。 – deanWombourne 2010-07-08 14:09:42
我做了我的代码更改,因为你说...但它仍然给我下面的错误..我是新的iPhone应用程序编程.. 'NSTextContainer'未申报(首次使用此功能) '容器'未申报在一次使用此功能) “字体”未声明(先入该函数使用) “NSFontAttributeName”未声明(在一次使用此功能) /“文字颜色”未声明(在一次使用此功能) ' NSForegroundColorAttributeName'未申报(首次使用此功能) 请指导我 – Pradeep 2010-07-09 08:16:54
