我已經做了編碼,檢查圖像是否越過特定區域或沒有,如何停止移動目標c中的圖像?
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
CGPoint loc=[touch locationInView:self.view];
if (touch.view==img2Obj) {
NSLog(@"image2");
img2Obj.center=loc;
currentx1=img2Obj.frame.origin.x;
currenty1=img2Obj.frame.origin.y;
//NSLog(@"top left corner x and y is %.1f and %.1f",img2Obj.frame.origin.x,img2Obj.frame.origin.y);
[self isImg1InPos];
}}
-(void)isImg1InPos {
int dx,dy;
dx=currentx1-x1;
dy=currenty1-y1;
if (abs(dx)<5 && abs(dx)<5) {
NSLog(@"Image must stop moving after this!!!");
[img2Obj setUserInteractionEnabled:FALSE];
}
//NSLog(@"unsigned int is %d",abs(dx));
}
我想要的圖像時停止傳遞狀態時移動。
[img2Obj setUserInteractionEnabled:FALSE];
但它不工作,誰能告訴我怎麼解決這個問題
很多感謝
條件是否滿足?即,NSLog是否打印該語句? – Ilanchezhian
